A 12.0-kg box resting on a horizontal, frictionless surface is attached to a 5.00-kg weight by a thin, light wire that passes without slippage over a frictionless pulley. The pulley has the shape of a uniform solid disk of mass 1.50 kg and diameter 0.450 m. (a) After the system is released, find the horizontal tension in the wire. (b) After the system is released, find the vertical tension in the wire. (c) After the system is released, find the acceleration of the box. (d) After the system is released, find magnitude of the horizontal and vertical components of the force that the axle exerts on the pulley

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.
