A block of mass m = 1.9 kg is attached to a string that is wrapped around the circumference of a wheel of radius R = 8.1 cm. The wheel rotates freely about its axis and the string wraps around its circumference without slipping. Initially, the wheel rotates with an angular speed ω, causing the block to rise with a linear speed v = 0.43m/s
Find the moment of inertia of the wheel if the block rises to a height of h
= 7.5 cm before momentarily coming to rest.
The moment of inertia of the wheel if the block rises to a height of h is 7.5 cm before momentarily coming to rest is 0.068 kg m².
We can use the conservation of mechanical energy to solve for the moment of inertia of the wheel. Initially, the system has kinetic energy, which is converted to potential energy at the highest point of the block's trajectory. Therefore, we can write:
Initial kinetic energy = Final potential energy
At the start, the wheel and block have kinetic energy due to the motion of the block:
KE i = 0.5 * m * v²
At the highest point of the block's trajectory, all of the kinetic energy is converted to potential energy due to the block's height above the ground:
PE_f = m * g * h
where g is the acceleration due to gravity.
Since the string is wrapped around the circumference of the wheel, the distance that the block moves upwards is equal to the distance that the string moves around the wheel, which is equal to the circumference of the wheel:
h = 2 * pi * R
Substituting this into the expression for potential energy:
PE_f = m * g * 2 * π * R
Equating initial kinetic energy with final potential energy:
0.5 * m * v² = m * g * 2 * π * R
Simplifying and solving for the moment of inertia of the wheel, I:
I = (m * v²) / (2 * g * π * R)
Substituting the given values:
I = (1.9 kg * 0.43 m/s)² / (2 * 9.81 m/s² * π * 0.081 m)
I = 0.068 kg m²
Therefore, the moment of inertia of the wheel is 0.068 kg m².

The fastest recorded pitch in Nippon Professional Baseball, thrown by Shohei Otani in 2016, was clocked at 102.5 mi/h. If a pitch were thrown horizontally at this speed, how far would the ball fall vertically (in ft) by the time it reached home plate, 60.5 ft away?
Incorrect: Your answer is incorrect.
ft
To solve this problem, we can use the kinematic equation for vertical motion under constant acceleration, which is given by:
[tex]y = vi*t + (1/2)at^2[/tex]
What is displacement?
Displacement is a vector quantity that refers to the overall change in position of an object from its initial position to its final position.
It is a straight line distance between the initial and final position, in a specific direction.
where y is the displacement (in this case, the vertical distance the ball falls), vi is the initial velοcity (0 in this case since the ball is thrοwn hοrizοntally), a is the acceleratiοn due tο gravity[tex](-32.2 ft/s^2)[/tex], and t is the time it takes fοr the ball tο reach hοme plate. We can find t by dividing the distance tο hοme plate by the hοrizοntal velοcity:
[tex]t = 60.5 ft / (102.5 mi/h * 5280 ft/mi * 1 h/3600 s) = 0.400 s[/tex]
Now we can use the kinematic equation to find y:
[tex]y = 0 + (1/2)(-32.2 ft/s^2)(0.400 s)^2 = -2.57 ft[/tex]
Note that the negative sign indicates that the displacement is downward. Therefore, the ball falls about 2.57 feet vertically by the time it reaches home plate.

It takes 80 pounds of force to
stretch a particular spring 2
inches. How much work is done
in stretching it from its relaxed
state a total of 4 inches?
[?] inch - pounds
Answer: 240 inch-lbs.
Explanation:
The spring constant, k, is given by:
k = (F/x)
where F is the force, x is the displacement, and k is the spring constant.
Using the given information, we can calculate the spring constant as:
k = (80 lbs / 2 in) = 40 lbs/in
To find the work done in stretching the spring from its relaxed state to a total of 4 inches, we need to integrate the force over the displacement:
W = ∫F dx
Since the force required to stretch the spring varies with displacement, we need to break up the integration into two parts: one from 0 to 2 inches, and another from 2 to 4 inches.
W = ∫0^2 F dx + ∫2^4 F dx
The first integral is:
∫0^2 F dx = ∫0^2 (kx) dx = (1/2)kx^2 = (1/2)(40 lbs/in)(2 in)^2 = 80 inch-lbs
The second integral is:
∫2^4 F dx = ∫2^4 (2k) dx = 2kx = 2(40 lbs/in)(4 in - 2 in) = 160 inch-lbs
Therefore, the total work done in stretching the spring from its relaxed state to a total of 4 inches is:
W = ∫0^2 F dx + ∫2^4 F dx = 80 inch-lbs + 160 inch-lbs = 240 inch-lbs
So, the work done in stretching the spring from its relaxed state a total of 4 inches is 240 inch-lbs.
A body of mass 1 kg is pushed at a constant speed against a vertically placed wall, with a constant force F, which forms an angle of 45 degrees with the horizontal, as in the picture. The sliding friction coefficient is 0.2. What is the intensity of the force F? For the acceleration of the heavier force, take g=10 m/s2.
The intensity of the force F is calculated to be approximately 2.83 N.
What is sliding friction coefficient?Coefficient of sliding friction is a value that measures force of sliding friction for particular surface type.
Weight = mg = 1 kg x 10 m/s² = 10 N (acting downwards)
F_vertical - Weight = 0
F_vertical = 10 N
As Frictional force = coefficient of friction x normal force
Frictional force = 0.2 x 10 N = 2 N (acting to the left)
F_horizontal = F x cos(45) = F / √2
F_horizontal - frictional force = 0
F_horizontal = frictional force = 2 N
F / √2 = 2 N
F = 2 N x √2
F ≈ 2.83 N
Therefore, the intensity of the force F is approximately 2.83 N.

PLEASE ANSWER THISSSSSSSSS!!!!!
The rate at which οil is flοwing is 0.494 m³/s. This means that the prοduct οf the fluid's density (ρ), crοss-sectiοnal area (A), and velοcity (v) is cοnstant.
What is Density?Density is a physical prοperty οf matter that represents hοw much mass is cοntained within a given vοlume οf a substance. It is defined as the amοunt οf mass per unit vοlume and is typically expressed in units οf kilοgrams per cubic meter (kg/m³) οr grams per cubic centimeter (g/cm³).
We can use the principle οf cοntinuity tο sοlve this prοblem. Accοrding tο this principle, the mass flοw rate οf a fluid remains cοnstant as it flοws thrοugh a pipe οf varying diameter.
Therefore, we can write:
[tex]\rho_1A_1v_1 = \rho_2A_2v_2[/tex]
where the subscripts 1 and 2 refer to the sections of the pipe before and after the constriction, respectively.
We can rearrange this equation to solve for the velocity of the oil in the pipe:
[tex]v_2 = (A_1/A_2) \times (v_1 \times (\rho_1/\rho_2))[/tex]
where A1 and A2 are the cross-sectional areas of the pipe before and after the constriction, respectively.
Using the given values, we get:
[tex]v_2 = (\pi/4) \times (1.11 m)^2 \times (8130 N/m^2 / 821 kg/m^3) / [(\pi/4) \times (0.666 m)^2] \times (6097.5 N/m^2 / 821 kg/m^3)[/tex]
v₂ = 1.74 m/s
Finally, we can calculate the rate at which oil is flowing using the formula:
Q = A₂ × v₂
Using the given values, we get:
Q = (π/4) × (0.666 m)² × 1.74 m/s
Q = 0.494 m³/s

A faulty model rocket moves in the xy-plane (the positive y-direction is vertically upward). The rocket's acceleration has components ax(t)=αt2
and ay(t)=β−γt
, where α
= 2.50 m/s4
, β
= 9.00 m/s2
, and γ
= 1.40 m/s3
. At t=0
the rocket is at the origin and has velocity v⃗ 0=v0xi^+v0yj^
with v0x
= 1.00 m/s
and v0y
= 7.00 m/s
.
The rocket travels a horizontal distance of 57.4 m before hitting the ground.
What is the initial speed of the rocket?The initial speed of the rocket is v0=√(v0x^2+v0y^2)=7.28 m/s.
What is the rocket's velocity at the maximum height?The rocket's velocity at the maximum height is zero, as it momentarily stops moving vertically and starts falling back down.
To solve this problem, we can use the kinematic equations of motion. Let's first find the velocity and position as a function of time:
vx(t) = v0x + ∫ax(t) dt = v0x + (1/3)αt^3
vy(t) = v0y + ∫ay(t) dt = v0y + βt - (1/2)γt^2
x(t) = ∫vx(t) dt = v0x t + (1/12)αt^4
y(t) = ∫vy(t) dt = v0y t + (1/2)βt^2 - (1/6)γt^3
Now, let's find the time t1 when the rocket reaches its maximum height:
ay(t1) = 0
β - γt1 = 0
t1 = β/γ = 6.43 s
At t1, the rocket's height is:
y(t1) = v0y t1 + (1/2)βt1^2 - (1/6)γt1^3
y(t1) = 7.00 m/s × 6.43 s + (1/2) × 9.00 m/s2 × (6.43 s)^2 - (1/6) × 1.40 m/s3 × (6.43 s)^3
y(t1) = 92.5 m
Now, let's find the time t2 when the rocket hits the ground. We can do this by solving for the positive root of the quadratic equation:
y(t) = 0
(1/2)γt^2 - βt - v0y = 0
Using the quadratic formula, we get:
t2 = (β + √(β^2 + 2γv0y))/γ = 8.01 s
Finally, let's find the horizontal distance traveled by the rocket:
x(t2) = v0x t2 + (1/12)αt2^4
x(t2) = 1.00 m/s × 8.01 s + (1/12) × 2.50 m/s4 × (8.01 s)^4

Two resistors of 5.0 and 9.0 are connected in parallel. A 4.0- resistor is then connected in series with the parallel combination. A 6.0-V battery is then connected to the series-parallel combination. What is the current through the 5.0- resistor?
Answer:
First, we need to find the equivalent resistance of the parallel combination of 5.0 and 9.0 resistors:
1/R = 1/5.0 + 1/9.0
1/R = 0.4 + 0.1111
1/R = 0.5111
R = 1/0.5111
R ≈ 1.955 ohms
The equivalent resistance of the parallel combination is approximately 1.955 ohms.
Next, we need to find the total resistance of the circuit:
R_total = 4.0 + 1.955
R_total = 5.955 ohms
The total resistance of the circuit is approximately 5.955 ohms.
Using Ohm's Law, we can find the current through the circuit:
I = V/R_total
I = 6.0/5.955
I ≈ 1.006 A
The current through the circuit is approximately 1.006 A.
Finally, we can use the current divider rule to find the current through the 5.0-ohm resistor:
I_5 = (R_parallel / (R_parallel + R_series)) * I_total
I_5 = (1.955 / (1.955 + 4.0)) * 1.006
I_5 ≈ 0.383 A
The current through the 5.0-ohm resistor is approximately 0.383 A.

4. A 25,000kg asteroid is flying towards the Earth at a speed of 1500.0m/s. How much Silly Putty would it take to stop the asteroid if we launched it at a velocity of -100.0m/s? Assume the Silly Putty sticks to the asteroid.
To solve this problem, we can use the principle of conservation of momentum, which states that the total momentum of a system remains constant if there are no external forces acting on it. We can set the momentum of the asteroid before the collision equal to the momentum of the asteroid-Silly Putty system after the collision.
The momentum of the asteroid before the collision is:
P_before = m_ast * v_ast
where m_ast is the mass of the asteroid and v_ast is its velocity.
The momentum of the asteroid-Silly Putty system after the collision is:
P_after = (m_ast + m_sp) * v_final
where m_sp is the mass of the Silly Putty, v_final is the velocity of the asteroid-Silly Putty system after the collision, which we assume to be zero.
We can equate these two expressions for momentum and solve for the mass of the Silly Putty:
m_sp = (m_ast * v_ast) / (-v_final)
Substituting the given values:
m_ast = 25,000 kg
v_ast = 1500.0 m/s
v_final = -100.0 m/s
m_sp = (25,000 kg * 1500.0 m/s) / (-(-100.0 m/s))
m_sp = 375,000 kg m/s / 100.0 m/s
m_sp = 3750 kg
Therefore, we would need 3750 kg of Silly Putty to stop the asteroid if we launched it at a velocity of -100.0 m/s.

What is pressure?Pressure is a physical quantity used to measure the force applied by an object to another object or by an object to a surface. It can be expressed as the force per unit area and is typically measured in units such as pounds per square inch (psi) or pascals (Pa). Pressure can be applied to gases, liquids, and solids, and is generated by the weight of the atmosphere, the force of gravity, and by the movement of air or liquids.

Answer: 0.1
Explanation:
To find the tension on the stone, we can use the centripetal force formula, which is given by F = (mv^2)/r, where m is the mass of the object, v is its velocity, and r is the radius of the circular path.
In this case, the stone is tied to a string and is moving in a circle of radius 50 cm (or 0.5 m), so we have:
F = (0.05 kg) x (1 m/s)^2 / 0.5 m
F = 0.1 N
Therefore, the tension on the string is 0.1 N.
So, the correct answer is 0.1.

A man stands on the roof of a building of height 14.0 m and throws a rock with a velocity of magnitude 32.0 m/s at an angle of 29.0 ∘ above the horizontal. You can ignore air resistance.
A) Calculate the maximum height above the roof reached by the rock.
Express your answer in meters
B) Calculate the magnitude of the velocity of the rock just before it strikes the ground.
Express your answer in meters per second.
C) Calculate the horizontal distance from the base of the building to the point where the rock strikes the ground.
Express your answer in meters.
Answer:
A) The maximum height above the roof reached by the rock can be found using the formula:
h = (v₀²sin²θ)/(2g)
where v₀ is the initial velocity (32.0 m/s), θ is the angle of the initial velocity (29.0°), and g is the acceleration due to gravity (9.81 m/s²).
Plugging in the values, we get:
h = (32.0²sin²29.0)/(2(9.81)) = 31.1 m
Therefore, the maximum height above the roof reached by the rock is 31.1 meters.
B) The vertical component of the velocity just before the rock strikes the ground is:
vᵥ = v₀sinθ - gt
where t is the time it takes for the rock to reach the ground.
We can find t by using the formula:
h = v₀sinθt - (1/2)gt²
where h is the height of the building (14.0 m). Rearranging this formula and solving for t, we get:
t = (v₀sinθ + sqrt((v₀sinθ)² + 2gh))/g
Plugging in the values, we get:
t = (32.0sin29.0 + sqrt((32.0sin29.0)² + 2(9.81)(14.0)))/9.81 = 4.01 s
Therefore, the vertical component of the velocity just before the rock strikes the ground is:
vᵥ = 32.0sin29.0 - 9.81(4.01) = -14.3 m/s
Note that the negative sign indicates that the velocity is directed downwards.
C) The horizontal distance from the base of the building to the point where the rock strikes the ground can be found using the formula:
d = v₀cosθt
Plugging in the values, we get:
d = 32.0cos29.0(4.01) = 96.4 m
Therefore, the horizontal distance from the base of the building to the point where the rock strikes the ground is 96.4 meters.

what two changes need to be made so that the plug is wired correctly ?
It is important to note that wiring a plug can be dangerous, and if you are not confident in your ability to do so, you should seek the help of a qualified electrician. Incorrectly wiring a plug can result in electrical shock.
What are the step for plug wired ?
The first change that may need to be made is to ensure that the correct wires are connected to the corresponding terminals on the plug. Typically, the green and yellow wire is connected to the earth terminal, the blue wire to the neutral terminal, and the brown wire to the live terminal.
How can you determine whether a plug is wired properly?Voltage can be measured with a multimeter. A probe should be inserted into each slot to measure the line voltage. A fully functioning outlet registers between 110 and 120 volts. Check the outlet and the wiring if there is no reading.

What is the relationship of the wavelength of a
particle and its mass?
a
The wavelength of a particle cannot
be measured.
b They are directly related.
C
The mass of a particle does not affect
its wavelength.
d They are inversely related.
The relationship of the wavelength of a particle and its mass is they are inversely related.
Option D is correct.
What is de Broglie frequency condition?The link between a particle's mass and wavelength is provided by the de Broglie wavelength equation: = h/p,
where is the wavelength, h is the Planck constant, and p is the particle's momentum.
This condition shows that a molecule's energy is contrarily relative to its frequency. Because momentum (p = mv) is defined as the product of mass and velocity, we can also say that a particle's wavelength is inversely proportional to its mass.
What is the Wavelength?A wavelength is the distance between two identical points (adjacent crests) in consecutive cycles of a waveform signal that travels in space or down a wire. In wireless systems, its length is typically measured in meters (m), centimeters (cm), or millimeters (mm).

Horizontal lines are referred to as being parallel to a x-axis in coordinate geometry. A line is referred to as horizontal if two points on the line share the same y-coordinate points.
What does a graph's x-axis / horizontal line represent?The intersection of the vertical and horizontal (X axis) real number lines is shown on the axis graph (Y axis). The Y axis is known as the dependent variable of the data set, whereas the X axis is typically used to refer to the independent variable of the data set.
In the line graph, how does X show up?The horizontal x-axis and vertical y-axis are the two axes of a line graph (vertical). A different type of data is indicated at each of the points where the axes connect, and (0,0). The x-axis is referred to as an independent axis since the numbers it represents are not reliant on any of the variables being assessed.
