What is the velocity of a 24 kg object with 108 kg m/s of momentum?

A) 3 m/s
B) 4.5 m/s
C) 6 m/s
D) 84 m/s

Answers

Answer 1

Answer:

The velocity of the object is 4.5 m/s

Explanation:

Momentum is equal to mass times velocity.  We can rearrange that relationship to say that velocity is equal to momentum divided by mass.  With that we can say:

v = 108 kg m/s / 24kg

v = (108 / 24) m/s

v = 4.5 m/s

A car weighs 11000 N on Earth. What is its mass?

A) 300 kg
B) 1122 kg
C) 0 kg
D) 107,800 kg

Answers

Weight is the measurement of the force of gravity, and it is mathematically defined as the mass of an object multiplied by gravitational acceleration: W = mg. On Earth, g is about 9.8 m/s². Rearranging the equation to find mass, m = W/g. Given our weight of 11000 N, the mass of the car would thus be m = 11000 N/9.8 m/s² = 1122 kg. So, the correct answer choice here would be B.

You are in a car traveling at 20 m/s. An ambulance is behind you traveling 35 m/s in the same direction. What frequency do you hear if the siren has a frequency of 550 Hz?

Answers

Answer:

The frequency heard is 576.78 Hz

Explanation:

The Doppler effect is defined as the apparent frequency change of a wave produced by the relative movement of the source with respect to its observer. In other words, this effect is the change in the perceived frequency of any wave motion when the sender and receiver, or observer, move relative to each other.

This is what happens in the first part of this problem, where the sender is train A and the receiver is train B. They are both moving in opposite directions. In this case, where both are in motion, the frequency perceived by the receiver will increase when receiver and transmitter increase their separation distance and will decrease whenever the separation distance between them is reduced. The following expression is considered the general case of the Doppler effect:

[tex]f'=f*\frac{v+-vR}{v+-vE}[/tex]

Where:

f ', f: Frequency perceived by the receiver and frequency emitted by the issuer respectively. Its unit of measurement in the International System (S.I.) is the hertz (Hz), which is the inverse unit of the second (1 Hz = 1 s-1)

v: Velocity of propagation of the wave in the medium. It is constant and depends on the characteristics of the medium. In this case, the speed of sound in air is considered to be 343 m / s

vR, vE: Speed ​​of the receiver and the emitter respectively. Its unit of measure in the S.I. is the m / s

±, ∓:

We will use the + sign:

In the numerator if the receiver approaches the emitter In the denominator if the emitter moves away from the receiver

We will use the sign -:

In the numerator if the receiver moves away from the emitter In the denominator if the emitter approaches the receiver

In this case you are in a car traveling at 20 m/s and an ambulance is behind you traveling 35 m/s in the same direction.

In this case the receiver, you in the car, moves away from the emitter, while the emitter, the ambulance, approaches the receiver behind you in the same direction. So the frequency is calculated by the expression:

[tex]f'=f*\frac{v-vR}{v-vE}[/tex]

Being:

f= 550 Hzv=343 m/svR= 20 m/svE= 35 m/s

and replacing:

[tex]f'=550 Hz*\frac{343 m/s-20 m/s}{343 m/s-35 m/s}[/tex]

you get:

f'= 576.78 Hz

The frequency heard is 576.78 Hz

3.1. A stone of mass 2kg is thrown vertically upward with a speed
of 20m's Calculate the maximum height reached.​

Answers

Answer:

20.41 m

Explanation:

Let's list out the relevant variables in this problem. Take the upwards direction to be positive and the downwards to be negative.

v₀ = 20 m/sv = 0 m/sa = -9.8 m/s² Δy = ?

We are using the fact that at maximum height, the object's velocity is 0 m/s right before it changes direction to fall vertically back down to Earth.

Find the constant acceleration equation that contains these four variables.

v² = v₀² + 2aΔy

Substitute the known values into the equation and solve for Δy, the maximum height.

(0)² = (20)² + 2(-9.8)Δy 0 = 400 - 19.6Δy -400 = -19.6Δy Δy = 20.4081632653

The maximum height of the stone is 20.41 m. Notice that its mass was irrelevant when solving for its maximum height when thrown.

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass. How fast are they traveling? How would you find your answer?

Answers

Answer:

They traveling at  along the direction of 55 kg kid.

Step-by-step explanation:

Conservation of momentum-

Momentum of a system is constant if there are no external forces acting on the system.

As they crash into each other and hold onto each other so that they move as one mass and no other force is acting on them, so conservation of momentum can be applied here.

The final direction of velocity will be opposite to the assumed direction of the mass of 40 kg.

This is a conservation of momentum problem. The equation relevant here is

[tex]\[m_1v_1+m_2v_2=\left ( m_1+m_2 \right )v_f\][/tex]

where m is the mass and v is the velocity. Because Amy and Jenny move as one mass after crashing (or colliding) with each other, this is an inelastic collision. What we to find is the final velocity, [tex]v_f[/tex], of both Amy and Jenny as a single body.

[tex]v_f=\frac{m_1v_1+m_2v_2}{\left ( m_1+m_2 \right )} = \frac{(55)(3)+(40)(5)}{(55+40)} = \text{3.84 m/s}.[/tex]

Explanation:

Thermal energy doesn't transfer, but remain a part of the internal energy of the system.Heat transfer's it's energy, like when you sit in a cold chair, then becomes warm.That's because the energy was transferred from your body to the chair.

Answer:

Thermal energy is the random movement of atoms or molecules present in an object or a system while heat energy is the measure of the degree of hotness or coldness due to the temperature difference between two objects. So, in a nutshell, heat energy is the flow of thermal energy in a system.

Radiation is released from the nuclei that undergo a reaction.A small amount of the mass in each nucleus that undergoes a reaction is converted to energy.

Hence, option (C) and (D) are correct.

What is nuclear reaction?

A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.

Instead of being referred to as a nuclear reaction, the process is simply referred to as a sort of nuclear scattering if a nucleus interacts with another nucleus or particle and they subsequently separate without altering the nature of any nuclide.

The kinetic energy of a body moving at a speed of 10 m / s is equal to 1000 J. What is the body mass

Answers

Answer:

m = 20 kg

Explanation:

Given that,

The speed of a body, v = 10 m/s

Kinetic energy of the body, K = 1000 J

We need to find the mass of the body. The formula for the kinetic energy of a body is given by :

[tex]K=\dfrac{1}{2}mv^2\\\\m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 1000}{(10)^2}\\\\m=20\ kg[/tex]

So, the mass of the body is equal to 20 kg.

As a cold air mass advances on a warm air mass, what usually comes before it?​

Answers

Answer: A cold front occurs when a cold air mass advances into a region occupied by a warm air mass. If the boundary between the cold and warm air masses doesn't move, it is called a stationary front.

Explanation: Two types of occluded front exist: the warm-type and the cold-type. They’re distinguished by the relative temperatures of the air mass ahead of the occlusion – in other words, the air mass ahead of the original warm front – and the air mass behind the cold front. If the air behind the cold front is colder than the air ahead of the occlusion, it shoves beneath that air (because it’s denser) to form a cold-type occluded front. If the air behind the cold front is warmer than the air ahead, it rides over it to form a warm-type occluded front – which appears to be the more common case. In either situation, the lighter warm air representing the air mass originally between the warm and cold fronts sits above the boundary between the two cooler air masses.
