<span>The egg doesn't break when it hits the sheet because the impact time is longer. Momentum means the egg is slowed rather than coming to an abrubt halt. The softer the object that the egg hits, the longer the time it takes to break. A sheet is so soft that the force is never high enough for the egg to break.</span>
F = m*a, mass times acceleration.
F = 15*10 = 150 N
The farther away an object is from the Sun the slower it orbits around it. The closer an object is from the Sun the faster it orbits around it.
The term you need to know is equilibrium. Technically it means that heat gained = heat lost. Normally in beginning chemistry classes the evidence for this condition is a stable temperature.
