The gravitational field strength = Defined as Gravitational Force per unit mass
Gravitational Field Strength =
= Gravitational Force Exerted / Mass of object exerted on
= (9.1*10⁴) / (1.1*10⁴)
= 9.1/1.1
≈ 8.27 N/kg
≈ 8.3 N/kg
Option (3) is the answer.
Heat=m*Lv where m is mass and Lv is latent heat of vaporization. So... you will change 50g to kg which is 0.05kg multiply it by 2,260,000J/kg you will get 113000J. :)
If there are two forces acting on a rocket, and the forces are equal and opposite, then they add up to zero, and there is no NET force at all on the rocket.
Then the rocket can only move at a constant speed in a straight line. It can't have any acceleration (change of speed or direction.)
I think it might be D because all waves travel through a medium. I might be wrong though.
ideal gas in ball assumed.
warmer = high pressure, ball deformed and stressed, could burst
cooler = low pressure, ball shrinks, could go soft.
ideal gas laws help calculate this
