I'm an arborist needing a 14oz weight to be able to be shot from like a crossbow vertically 120 feet. this is for me to have a strong tied to the weight to then pull my rope up to climb the tree and access the canopy. what is the amount of force i need to create in say 30 inches for 14oz to shoot up 120 feet?

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.
