Why does lowering the control rods in a nuclear reactor reduce the amount of energy released each second from the nuclear fuel?

The boron control rods absorb slow-moving neutrons (thermal neutrons), which means that there are less available neutrons in the reactor. Since nuclear fission requires a collison between a neutron and a ura...

A pendulum has a frequency of 0.80 Hz, calculate the periodic time of the pendulum.

You need to use the equation that relates frequency and period; period = 1/frequency Then all you need to do is plug in the frequency to get the periodic time: period = 1/0.80 Hz = 1.25 s [NOTE: If you're co...

How deep is the water if it takes a pulse of ultrasound 0.8s to be received back at the boat. the speed of ultrasound is 1600m/s in water

firstly we know how fast the wave is travelling and we know for how long so using our speed equals distance over time equation we can rearange for distance (D= VT). we can the plug in our speed(V) and our ti...
