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.
Answer:
1.2 amps :)
Explanation:
A heater has a resistance of 10.0 Ω. It operates on a 12.0 V. What is the current through the resistor?
Known:
Unknown:
I = V/R
= 12.0 V / 10.0 Ω
= 1.2 amps
Answer:
power is given by work done divide time taken
P=w/t
therefore Pt=w
270x42=11,340.J
Answer:
Unsaturated Solution: Less amount of salt in water, clear solution, no precipitation. Saturated Solution: The maximum amount of salt is dissolved in water, Colour of the solution slightly changes, but no precipitation. Supersaturated Solution: More salt is dissolved in water, Cloudy solution, precipitation is visible
C. You’re welcome
