You have a device that takes temperature measurements and runs off of solar power. How often it is programmed to take a measurement will affect how much power it uses--more frequent measurements, more power.

You push a block to the top of an inclined plane. The mechanical advantage of the plane is 5. The inclined plane is 10 meters long. What is the height of the inclined plane? 0.5 m 2 m 50 m 10 m

The capacity of the muscle to use a single maximum force over any range of motion is

A car drives over a hilltop that has a radius of curvature 120 m at the top of the hill. at what speed would the car be traveling when it tires just barely lose contact with the road when the car is at the top of the hill?

a bowling ball is rolling down the hall at a constant speed of 1.5 m/s. how far will the ball roll in 6.0 s.

If you do 1000j of work on a system and remove 500j of heat from it, what is the change in its internal energy

Two children stretch a jump rope between them and send wave pulses back and forth on it. The rope is 4.5 m long, its mass is 0.42 kg, and the force exerted on it by the children is 71 N.

An object will only change its motion if a force is directly applied to it. is this a true statement?
