The correct answer to the question is: C) They control the rate of reaction.

EXPLANATION:

The control rod plays a crucial role in nuclear reaction. The main function of the control rod is to control the rate of reaction.

The nuclear chain reaction becomes uncontrolled when number of neutrons are not controlled. It is so because each decay of radioactive uranium or plutonium produces three extra neutrons which again decay the radioactive sample at a faster rate.

The control rods are made up of boron,indium and cadmium like substances. They absorb the thermal neutrons generated in each decay of radioactive specimen. In this way, they control the rate of reaction.

I think the correct answer from the choices listed above is the third option. Control rods are used in nuclear reactors to control the fission rate of uranium and plutonium. They control the rate of reactions by absorbing neutrons. Hope this answers the question. Have a nice day.

A car is moving from rest and attained a velocity of 80 m/s. Calculate the acceleration of the car after 5 s?

soldi70 [24.7K]

Answer:

400 m/s

Explanation:

If it is moving at a velocity of 80 m/s from rest, then after 5 s it would be at 400 m/s.

80 x 5 = 400

A magnet is made from materials that is magnetized and create its own persistent magnetic field while a electromagnet is mad from coil of wire which acts as a magnet when electric current passes through it.

katrin2010 [14]

Artificial gravity is created by rotating the cylinder

So here we can say that the acceleration is due to centripetal acceleration

So here we know that the formula of centripetal acceleration is given by

$a_c = \frac{v^2}{R}$
