Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.For such a collision<span>, the forces acting between the two objects are equal in magnitude and opposite in direction</span>
Well let see, we don't have any information about the initial distance we have to use our logic
assuming that the distance moves from 1 to 2 m with initial speed , it means that the distance factor is 2
Since the initial speed has doubled, it would be very likely that the factor of the distance is MORE THAN 2 . Find the answer that either got 3 or 4 distance factor
hope this helps
Answer:
Periodic
Explanation:
A periodic (or repetitive) wave has continuously repeating pattern with characteristics such as amplitude, wavelength and frequency. In a periodic wave, a series of pulses that are evenly timed would be created. In other words, the wave pattern in a periodic wave repeats at regular intervals.
An example of a periodic wave is the sound from the strings of a violin.`
Answer:
Explanation:
The motion of the bullet is a uniformly accelerated motion, therefore we can find its acceleration by using the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
For the bullet in this problem:
u = 350 m/s is the initial velocity of the bullet
v = 0 is the final velocity (the bullet comes to a stop)
s = 0.125 m is the stopping distance of the bullet
Therefore, by solving the equation for a, we find its acceleration:
And the negative sign tells that the direction of the acceleration is opposite to that of the velocity.
Answer:
D.The mass and the latent heat of fusion.
Explanation:
When a block of ice is at its melting point, it doesn't need any additional heat in order to reach that temperature. Instead, it needs heat in order to break the bonds between the molecules and change state from solid to liquid. During the phase change, the temperature of the substance does not change, since all the heat provided is used to break the bonds between the molecules.
The heat needed for the phase change is
where
m is the mass of the block
is the latent heat of fusion
Therefore, we see that the correct answer is
D.The mass and the latent heat of fusion.
