Answer:
option E.
Explanation:
When the ball is at the highest point the velocity of the ball is zero.
At the height point the kinetic energy is zero and potential energy is maximum.
At maximum point momentum cannot be maximum because velocity is zero.
Acceleration on the ball is equal to acceleration due to gravity on the ball.
Hence, the correct answer is option E.
Control rods<span> are </span>rods<span>, plates, or tubes containing a neutron absorbing material (material with high absorbtion cross-section for thermal neutron) such as boron, hafnium, cadmium, etc., used to </span>control<span> the power of a nuclear reactor.
so the statement that describe a control rod is:
</span><span>Control rods are lowered into the reactor to slow down the reaction by absorbing neutrons.</span>
