What is 6 °C in °F? round to one decimal place.

Answer:

The smaller the hole, the more force.

We are given:

Mass of the Crate(m) = 71 kg

Applied force(F) = 577 N

Resolving the applied force:

To solve this problem, we will first make a free-body diagram (attached)

The Applied force has been resolved into 2 components denoted by a thinner line and 'g' is the acceleration due to gravity

We found the values by using basic trigonometry

Finding the Normal Force:

Normal force is equal and opposite to the net force applied on the ground. So, we will subtract the vertical component of the applied force from the weight of the crate.

Normal force = mg - F*Sin(27°)

Normal force = [(71)*(9.8)] - [ (577)(0.454) ]                           [g = 9.8 m/s²]

Normal Force = 433.84 N

Gravitational force = G · (mass₁) · (mass₂) / (distance)

(distance²) = G · (mass₁) · (mass₂) / (Gravitational force)

G = 6.67 x 10⁻¹¹ n-m² / kg²  (the "gravitational constant")

Distance²  = (6.67 x 10⁻¹¹ n-m² / kg²) (28,500 kg) (2.2 x 10⁸ kg) / (39 N)

Distance² = (6.67 · 28,500 · 2.2 x 10⁻³ N-m²) / (39N)

Distance²  =  (418.209 N-m²) / (39N)

Distance²  =  10.72 m²

Distance = 3.275 meters

An absurd scenario, but that's by golly what the math says with the numbers provided.  I guess it's a teeny tiny planet orbiting 3.275 meters outside a teeny tiny black hole.

Answer:

The mass of the copper is 3.00kg

Explanation:

Answer:

A. 10023.75 Watts

B. 13.44 horse power

Explanation:

A. Determination of the power in Watts.

We'll begin by calculating the energy of the cheetah. This can be obtained as follow

Velocity (v) = 27 m/s

Mass (m) = 110 kg

Kinetic energy (KE) =?

KE = ½mv²

KE = ½ × 110 × 27²

KE = 55 × 729

KE = 40095 J

Finally, we shall determine the power in Watts. This can be obtained as follow:

Kinetic energy (KE) = 40095 J

Time (t) = 4 s

Power (P) =?

Power = Energy /time

Power = 40095 / 4

Power = 10023.75 Watts

B. Determination of the power in horse power.

Power in Watts = 10023.75 Watts

Power in horse power =?

Recall:

746 Watts = 1 hp

Therefore,

10023.75 Watts = 10023.75 / 746

10023.75 Watts = 13.44 hp

Therefore, the power in horse power is 13.44 hp

Answer:

-8.3 m/s²

Explanation:

The acceleration of an object is defined as the change in velocity over the change in time.

We are given the velocity of the bus, 25 m/s, and the time it takes the bus to stop, 3.0 s.

We know that if the bus stops, its velocity must be 0 m/s. Therefore, we can use these numbers to substitute into the acceleration formula.

The magnitude of the average acceleration of the bus while braking is 8.3 m/s².

However, in order for the bus to slow down and stop, the acceleration must have the opposite sign of the velocity.

This means that the acceleration is negative whilst the velocity is positive. So, the average acceleration of the bus while braking is -8.3 m/s².

Answer:

0.667 cm

Explanation:

|F_1on3| = |F_2on3|

k×q1×q3/x^2 = k×q2×q3/(d-x)^2

q1/x^2 = q2/(d-x)^2

(d-x)^2/x^2 = q2/q1

(d-x)/x = sqrt(q2/q1)

(2 - x)/x = sqrt(4×q/q)

(2 - x)/x = 2

2 - x = 2x

2 = 3x

x = 2/3

x= 0.667 cm

Answer:

L = 2 J.s

Explanation:

The angular momentum of an object travelling in a horizontal circle is given by the following formula:

[tex]L = mvr[/tex]

where,

L = Angular momentum = ?

m = mass = 0.8 kg

v = linear speed = rω

r = radius of circular path = length of rope = 0.5 m

ω = Angular Speed = 10 rad/s

therefore,

[tex]L = mr^2\omega\\L = (0.8\ kg)(0.5\ m)^2(10\ rad/s)\\[/tex]

Answer:

What are igneous rocks?

Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies

Answer:

time=4, answer choice A

time=5.5, answer choice B

Explanation:

This is taken from the kinematic equation, v=vo+(1/2)at^2

Velocity at time 4 = 30+(2.5)(4)^2

Velocity at time 5.5 = 30+(2.5)(5.5)^2

Velocity at time 4 seconds = 70 m/s

Velocity at time 5.5 seconds = 105.63 m/s

Answer:

K.E = 156.25 Joules.

Explanation:

Given the following data;

Mass = 0.5kg

Velocity = 25 m/s

To find the kinetic energy;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Substituting into the equation, we have;

[tex] K.E = \frac{1}{2}0.5*25^{2}[/tex]

[tex] K.E = 0.25 * 625 [/tex]

K.E = 156.25 Joules.

Answer:

700ma

Explanation:

all u do is have to add them up.

Ohm's law allows us to calculate the result for the value of the current when we change the resistance of the circuit:

Ohm's law establishes that voltage is proportional to current and we call the constant of proportionality resistance in a circuit.

           V = i R

Where V is the voltage, i the current and R the resistance of the circuit.

They indicate that the source supplies a current of i = 200 mA = 0.200 A at a load of R = 2 kΩ = 2 10³ Ω

Let's find the source voltage.

           V = 0.200 2 10³

           v = 400 V

Now with this voltage let's find the current for the new load of R = 50 Ω

          i = V / R

          i = 400/50

          i = 8 A

In conclusion using Ohm's law we can calculate the result for the value of the current when we change the resistance of the circuit is:

Answer:

Explanation:

By Ohms Law, Voltage = Current * Resistance

Keeping the voltage the same and doubling the resistance, the current will be halved.

So the new current = 1.5/2 = 0.75A

By using Ohms law,  the current will be 0.75A.

Ohm's law states that the current flowing through a resistance is proportional to potential difference across the resistance under constant temperature and pressure conditions. Ohm's law can be expressed as:

V =IR

Here, I = 1.50 AR = R Ωso, V = 1.50 R Now Voltage is same but resistance is doubled so new resistance is

Now, put the values of given data in ohms law formula:

2RI = 1.50 R/ 2R = 0.75A

Hence current is 0.75A
