3.00 m3 of a fixed mass of a gas at 150 kPa. Calculate the pressure if the volume is reduced to 1.20 m3 at a constant temperature.
Answer:
P₂ = 375 kPa.
Explanation:
Given that,
Initial volume, V₁ = 3 m³
Initial pressure, P₁ = 150 kPa
Final volume, V₂ = 1.2 m³
We need to find the final pressure.
At constant temperature,
[tex]P\propto \dfrac{1}{V}\\\\P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{150\ kPa\times 3\ m^3}{1.2\ m^3}\\\\P_2=375\ kPa[/tex]
So, the new pressure is 375 kPa.

12. An unbalanced 6.0 newton force acts eastward on an object for 3.0 seconds. The impulse
produced by the force is
Answer:
Impulse=18Ns
Explanation:
Impulse= force*time
Plug in known values...
I=6N*3s
I=18Ns
The impulse produced by the force is 18Ns
What is Impulse?
Impulse is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. Impulse= force*time Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time.Given:
F= 6.0N
t= 3.0 s
On substituting these values in the above formula:
[tex]I=6N*3s\\ \\I=18Ns[/tex]
Thus, The impulse produced by the force is 18 Ns.

Explanation:
13 A lawn-mower is pushed with a force of 50 N.
If the angle between the handle of the mower
and the ground is 30°,
(i) Calculate the magnitude of the force that
is pressing the lawn-mower directly into
the ground.
(ii) Calculate the magnitude of the effective
force that moves the mower forward.
(iii) Why does the lawn-mower move forward
and not downward into the ground?
Answer:
13. (i) The magnitude of the force that is pressing the lawn-mower directly into the ground is 25 N
(ii) The magnitude of the effective force that moves the mower forward is approximately 43.3 N
(iii) Because there are no net downward force acting on the lawn-mower
Explanation:
13. The given force pushing the lawn-mower = 50 N
The angle at which the force acts = 30° to the ground
The component of the pushing force are;
(i) The magnitude of the force that is pressing the lawn-mower directly into the ground = The vertical component of the pushing force
The vertical component of the pushing force, [tex]F_y[/tex] = 50 N × sin(30°) = 25 N
∴ The magnitude of the force that is pressing the lawn-mower directly into the ground = [tex]F_y[/tex] = 25 N
(ii) The magnitude of the effective force that moves the mower forward = The horizontal component of the pushing force
The horizontal component of the pushing force, Fₓ = 50 N × cos(30°) = 25·√3 N ≈ 43.3 N
∴ The magnitude of the effective force that moves the mower forward = 25·√3 N ≈ 43.3 N
(iii) The lawn mower moves forward and not downwards because according to Newton's first Law of motion, the lawn-mower moves forward because it is being acted on by a net forward directed horizontal force
However, according to Newton's third law, the reaction of the ground is equal to the weight of the lawn mower, therefore, there are no net vertical force acting on the lawn-mower, such that the lawn-mower remains in the initial horizontal level and does not move downward into the ground.

Calculate the wavelength of light that has a frequency of 5.2 x 1012 1/s.
Answer:
Wavelength = 5.77 * 10^-5 meters.
Explanation:
Given the following data:
Frequency of light = 5.2 *10^12 Hz
We know that the Speed of light = 3.0 * 10^8 m/s
To find the wavelength of light;
Mathematically, wavelength is calculated using this formula;
[tex] Wavelength = \frac {speed}{frequency} [/tex]
Substituting into the equation, we have;
[tex] Wavelength = \frac {3*10^{8}}{5.2 *10^{12}} [/tex]
Wavelength = 5.77 * 10^-5 meters.

Answer:
Explanation:
People are wild about amusement parks. Each day, we flock by the millions to the nearest park, paying a sizable hunk of money to wait in long lines for a short 60-second ride on our favorite roller coaster. The thought prompts one to consider what is it about a roller coaster ride that provides such widespread excitement among so many of us and such dreadful fear in the rest? Is our excitement about coasters due to their high speeds? Absolutely not! In fact, it would be foolish to spend so much time and money to ride a selection of roller coasters if it were for reasons of speed. It is more than likely that most of us sustain higher speeds on our ride along the interstate highway on the way to the amusement park than we do once we enter the park. The thrill of roller coasters is not due to their speed, but rather due to their accelerations and to the feelings of weightlessness and weightiness that they produce. Roller coasters thrill us because of their ability to accelerate us downward one moment and upwards the next; leftwards one moment and rightwards the next. Roller coasters are about acceleration; that's what makes them thrilling. And in this part of Lesson 2, we will focus on the centripetal acceleration experienced by riders within the circular-shaped sections of a roller coaster track. These sections include the clothoid loops (that we will approximate as a circle), the sharp 180-degree banked turns, and the small dips and hills found along otherwise straight sections of the track.

A man drives south to work every
day. If his 55 mile commute
usually takes 0.75 hours, what is
his average velocity?
The man's average velocity is 73.3 mph (miles per hour).
What is average velocity?Average velocity is a measure of the rate of displacement of an object in a given direction. It is the total displacement of the object divided by the total time taken to cover that displacement. In other words, it is the distance an object travels divided by the time it takes to travel that distance. Average velocity is an important concept in physics, as it can provide insight into the motion of an object and the forces acting upon it. Average velocity can be calculated using the equation: velocity = displacement/time.
This can be calculated by dividing the distance (55 miles) by the time (0.75 hours). Mathematically, this can be expressed as:
velocity = (distance / time)
velocity = (55 miles / 0.75 hours)
velocity = 73.3 mph

what hapenes to the wavelength of a wave if the frequency of the wave is increased?
Answer: The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Imagine a universe in which, like in ours, there are two kinds of charges (positive and negative), with the like charges repelling and unlike charges attracting each other, but with the electric force somewhat different from Coulomb's Law. Instead of varying with inverse distance squared, the force between charges in this imagined world would vary with the inverse distance cubed. In such a universe, would the static charges still always be distributed on the surfaces of conductors?
Answer:
the static charge is not always distributed on the surface of the conductor, there are also charges in the volume but of lesser magnitude
Explanation:
In this hypothetical system the electric force is of type
F = [tex]k' \frac{q_1 q_2 }{r^2}[/tex]
in this case the force decays to zero much faster,
if we call Fo the force of Coulomb's law
F₀ = [tex]k \frac{q_1 q_2 }{r^2}[/tex]
assuming the constant k is the same
the relationship between the two forces is
F / F₀ = 1 / r
F = F₀ / r
when analyzing this expression the force decays much faster to zero.
In an electric conductor, charges of the same sign may not feel any repulsive force from other charges that are at a medium distance, so there is a probability that some charges are distributed in the volume of the material, this does not happen with coulomb's law
Consequently, the static charge is not always distributed on the surface of the conductor, there are also charges in the volume but of lesser magnitude

A. 15m/s^2
B. 5m/s^2
C. 20m/s^2
D. 3m/s^2
Answer:3 m/s
Explanation:
The resulting acceleration to move the 5Kg box is equal to 3m/s². Therefore, option (D) s correct.
What is acceleration?Acceleration can be defined as the rate of change in the velocity of an object with respect to time. The acceleration of an object is a vector parameter with both magnitude and direction. Acceleration is also defined as the first derivative of the velocity w.r.t. time and the second derivative of position w.r.t. time and
According to Newton's 2nd law of motion, the force is equal to the product of the mass (m) and acceleration.
F = ma
And, a = F/m
Therefore, the acceleration (a) inversely proportional to the mass (m).
Given, the force used to move the box, F = 15 N
The mass of the given Box, m = 5 Kg
The resulting acceleration, a = 15/5 = 3 m/s²
Therefore, the acceleration of the box is equal to 3 m/s² when it is pushed with a force of 15 N.
