Answer:
yes the acceleration changes..
Explanation:
as we know that that acceleration is a vector quantity, hence it changes with the change in either it's magnitude or direction and both and here in this condition the car changes it's direction from west to east hence it changes the direction so the acceleration changes too.

A force can be considered a push or pull

The bending of light as it passes into a transparent material of different optical intensity is known as refraction. The correct option among all the options given in the question is option "C".It can never be
reflection as reflection is the bouncing of the light from a surface and so
option “A” can easily be negated. The last option or option
“D”<span> conversion and it mean converting something to
another and that means a total change of form. So the last option should also
be negated. The second option can also be negated.</span>
<h2>Answer:</h2>
<u>The correct option is </u><u> B.the empirical evidence that is collected during the experiment. </u>
<h2>Explanation:</h2>
A scientific experiment is the one that is not biased and it must be based upon actual data facts with the details dependent upon analysis and research. Empirical Evidence is that evidence is the information received by means of the senses, particularly by observation and documentation acquired through experimentation. Therefore B is the required answer.
Answer:
- Momentum is conserved
- Some kinetic energy is converted into thermal energy
Explanation:
Collision occurs when an object exert force on another. Collision can either be elastic or inelastic depending on whether the bodies stick together or separates after collision.
For elastic collision, the bodies separates after collision and due to this both their momentum and energy are conserved. Both separated object doesn't loose energy as such during collision and they possesses greater momentum.
In inelastic collision, the bodies stick together after collision. Their momentum is conserved but not their kinetic energy since they are not free to move independently.
Based on the question, the type of collision that occur is an inelastic collision since they stick together in air after collision. Some of the kinetic energy of the particles are turned into vibrational energy of the atoms leading to heating effect. Based on this, the following are true
- Their momentum before and after collision is conserved
- Some kinetic energy is converted into thermal energy(heat)
