At the end of the laps, the runner's displacement is zero.
Explanation:
it holds protons and neutrons together
Answer:
Explanation:
We can use the equation for the speed
where x is the distance and t the time. In this case we know that the time spent was 2 hours and the distance was 150km. By replacing we have
I hope this useful for you

Options:
(a) Total kinetic energy of the system remains constant.
(b) Total momentum of the system is conserved.
(c) Both A and B are true.
(d) Neither A nor B are true.
Answer:
(b) Total momentum of the system is conserved.
Explanation:
An inelastic collision is a type of collision in which momentum is conserved and kinetic energy is not conserved. That is, there is loss of kinetic energy.
In an inelastic collision:
Total momentum before collision = Total momentum after collision
An example of inelastic collision is seen in the ballistic pendulum, The ballistic pendulum is a device in which a projectile such as a bullet is fired into a suspended heavy wooden stationary block.
That depends on what "objects" refer to.
If "objects" refer to the ones on Earth, then it is TRUE. These objects are in motion relative to the sun same as with Earth itself.
<span>If "objects" refer to the ones outside earth, then it may be a TRUE or FALSE depending on how far or near they are from the sun.</span>
