Areactor operating at 1 mw is scrammed by instantaneous insertion of $5.00 of negative reactivity. approximately how long does it take the power to drop to 1 milliwatt?

time is 3333.33 min or 55.55 hr

Explanation:

given data

reactor operating = 1 MW

negative reactivity =  $5

power = 1 miliwatt

to find out

how long does it take

solution

we know here power coefficient that is

power coefficient =

power coefficient = 1

so time required to reach power is

power =  reactivity × time / power coefficient + reactor operating

1 × = -5 t / 1  +  1 ×

5t =   -

t = 199999.99 sec

so time is 3333.33 min or 55.55 hr

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
