Answer:
0.582 MeV
2.45 MeV
Explanation:
=Electron rest energy
(a) 0.500c to 0.900c

Energy required is 0.582 MeV
(b) 0.900c to 0.990c

Energy required is 2.45 MeV
70kg
1 earth gravity
80 M of height

54917.2 Joules of energy
Mrs. Stark has 54,917.2 Joules of energy.
Voltage = current * resistance
V = I*R
I = 4 A
R = 2 ohm
V = 4 A * 2 ohm
= 8 volt
The movement of fluid as a result of differential heating or convection. Earth convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global scale flow of magma.
