Question

The force of gravity between two planets depends on their masses and distance apart planetary atmospheres. rotational motions. all of the above Thermal energy is normally measured in units of calories. joules. both of the above. neither of the above. When you double the voltage in a simple electric circuit, you double the current. the resistance. both the current and the resistance. neither the current nor the resistance. The vibrations along a transverse wave move in a direction along the wave. perpendicular to the wave. both of the above neither of the above

Explanation / Answer

F = G*m1*m2/r12^2

m1 , m2 are masses of planets

r12 = seperation between planets

Force depends onmasses and distance apart

calories

option (A)

----------------

from ohms law

v = iR

R = resistance of circuit

as voltage is doubled , the current doubles

option (A)

++++++++++++

perpendicular to the wave
