Answer:
Gravity? is it multiple choice?
It would be a neutral,
The acidity of water is 7 as well
Work Done = Force x Distance Moved
Work Done = 25 x 15 = 375 Joules
1. If we increase the distance to twice it's original value, the light intensity is reduced by one-fourth, the light intensity would be:
I0/4
2. rms magnetic field is inversely proportional to distance, so the new rms magnetic field would be:
B0/2
3. average energy density is inversely proportional to the square of the distance, so the new average energy density is:
E0/4
