They both have kinetic energy because they are both moving and have force.
Hope this helped! :)

The answer is that it is an elastic collision.
<u>Explanation:</u>
When two objects come in direct contact with each other, the collision occurs. It is the event in which two or more bodies exert forces on each other in about a relatively short time.
As a result of a collision, No losses in the kinetic energy.
The formula for an elastic collision of momentum is given by
m1u1 +m2u2 = m1v1 + m2v2
where m1,m2 represents the mass of 1st and 2nd body
u1, u2 represents the initial velocity of the first and second body
v1, v2 represents the final velocity of the first and second bodies.
During a collision, the kinetic energy before the collision will be equal to the kinetic energy after the collision.
Smaller the force, greater the collision acting upon the object.
Answer:
The correct answer is C: Disposal of radioactive waste.
Explanation:
During nuclear fission reactions, many intermediate radioisotopes are produced. For example, uranium releases different mass distribution isotopes and these isotopes emit radiations.
Most harmful isotopes for the environment are strontium and cesium because these have half-lives and an inclination of mixing in food chains.
When radioactive wastes are removed from nuclear reactors they flow towards the swimming pool and also have the tendency to isolate the short-lived isotopes from the environment.
Therefore, radioactive waste disposal has always remained a major problem
<span>To produce a charge of 1.15 Coulombs in an object, we need to transfer = 1.15/(charge on an electron) number of electrons
As we know that, total charge on an electron = 1.60217662 Ă— 10 ^-19 coulombs
Hence, number of electrons required to move = 1.15/(1.60217662 Ă— 10 ^-19)
= 0.71777 x 10^19 electrons, i.e. 7.17 x 10^18 electrons upto 3 significant figures</span>
