The radiation pressure at earth’s surface is 6 mpa. consider a space ship with a surface area of 100 100 m2 and mass of 104 kg. if released with an initial velocity of 0, what is the speed with which the ship could reach the orbit of mars? assume the pressure does not change. also ignore angular momentum. the radius of earth’s orbit is 1.5 1011m while mars’ orbit radius is 2.3 1011 m.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
