Answer:

option (D)

Explanation:

It is controlled by the amount of neutrons available.

The rate of fission of heavy element is controlled by the number the number of neutrons. in the fission reaction of Uranium - 235, when one neutron is bombarded on one Uranium 235, three neutrons, small elements along with lot of energy is produced. Now three neutrons bombard three Uranium 235 atoms so that the lot of amount of energy is liberated. it is called uncontrolled chain reaction.

When the number of neutrons are absorbed and only one neutron is available for fission, then energy is in controlled manner and it is called controlled fission reaction. In this reaction, controlled amount of energy is released.

Which of the following experiments could be used to determine the inertial mass of a block? A. Place the block on a rough horizo

valentinak56 [21]

Answer:

D, using a spring scale to exert a force on the block. Measure the acceleration of the block and the applied force

Explanation:

For this you would use the net force equation acceleration=net force * mass however you will want to isolate mass so it would be acceleration/ net force to get mass. Then process of elimination comes to play.
