Answer:
ou have I=200mA, E=40J, t=30s, and you want to find the voltage drop.
First, you should know that P=V⋅I , so V=PI
Second, you have the amount of energy converted in a certain amount of time, so E=P⋅t
So, find the power and use it to find the voltage drop.
this works , but i thought energy was defined by W = P * t whitch would then be P = W/t
Because of nuclear fusion , the sun combines gas that makes other gases and releases energy
Action: you muscles exert force that acts on the bunching bag. The bag on the other hand exerts force of reaction directed in a same line with the force exerted by your fist.
The basketball acts on the rack with force of its weight (in this case we can say it equals basketball's force of gravity), and the rack acts on the ball with the normal force.
A is the answer you can believe me
