A student is pulling a 15 kg cart up a ramp with a rope that is parallel to the surface of the ramp. If the ramp is angled at 25 degrees, calculate the following: Draw the FBD for this situation.
Find the force perpendicular and normal force exerted on the cart?
Find the force parallel and friction force exerted on the cart?

Which of the following represents an upside-down image? o a. +doo b. -doo c. +mo d.-m

Arod of some material 0.20 m long elongates 0.20 mm on heating from 21 to 120°c. determine the value of the linear coefficient of thermal expansion [in (degrees c)^-1] for this material.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
