Explanation:

Question 1 (An inclined plane wrapped around a cylindrical post is a ___)

A screw is defined as an inclined plane wrapped around a cylindrical post. A lever is a rigid bar, a ramp is a simple inclined plane (not wrapped around a post), and a block and tackle is a system of pulleys. So the correct option is screw.

Power is the rate of doing work. The watt is the unit of power (1 watt = 1 joule per second). m/s is a unit of speed, second is a unit of time, and joule is a unit of energy/work. So the correct option is watt.

Answer:

D. screw
