Two objects of same material are travelling near you. object a is a 1.4 kg mass traveling 14.2 m/s; object b is a 2 kg mass traveling 5 m/s. which object would make you feel worse if you are hit by it?

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.
