Answer:
Explanation:
work done=force*displacement
=350N*15m
=5250 joule
Answer:
-17.5 nC
Explanation:
charge A = -30 nC
charge B = -5 nC
After adding them it would be the average of the two charges because of the getting same voltage difference. so
c = (-30+(-5)) / 2 nC
c= -17.5 nC
answer is -17.5 nC
Answer:
The balloon expands in the number of particles per cubic centimeter decreases. This happens because as it expands there is a decrease in the density of area. The Dead Sea is a solution that is so dense that you easily float on it.
mass of one liter of water= 1kg
Archimedes says:
F= m g = 1 kg* 9.81 m/s^2 = 9.81 newtons
The electric field depends not on the magnetic field, but change in magnetic field. if the magnetic field is constant. electric field will be zero.
