When the mover pushes the box up the ramp there is friction between the box and the ramp What is the efficiency of the ramp?

It depends on the mass of the box, the force exerted, the total displacement and the height the box was moved.

How does a heat mover absorb heat from cold air?
A good example of this process is a refrigerator. Electricity is used to power the refrigerator to keep it cool. The room that the fridge is in is warmer. Normally the warm air from the room should flow into the refrigerator until they are the same temperature. The heat mover, which is the refrigerator in this case, absorbs the heat the cooler air absorbs, and moves it back into the room. This keeps the fridge at a constant temperature.
A device that heats your home by transferring thermal energy from a region of low temperature to a region at a higher temperature is a?
I think you're talking about a heat engine or heat mover..
Why is a refrigerator called a thermal energy mover On what scientific principles does it work?
It removes thermal energy on what ever you place on the refrigerator. The first principle is transfer of heat, the second is solidification or vapourization.
What is the best way to finger my girlfriend?
To start i always gently go up and down my girlfriends leg. Then i begin to rub her vagina. Then i start with one finger (pointer or index), then a couple minutes into it i add my middle finger. Then i mover my fingers forward and backwards like two legs walking on her g spot. Which is her favorite
If a mover pushes on a large box but it does not move what is the net force on the box?
it is zero
What allows smooth joint movement?
The joints in our body contain a fluid known as the synovial fluid which facilitates smooth movement as it reduces the friction between the bones
When a mover puts furniture on a dolly with wheels which type of friction is the mover using?
There are separate answers for each part of this situation: 1. As the mover lifts the piece of furniture to the dolly, s/he will probably use a normal force (no friction) against the bottom of the piece, while at the same time pressing and lifting against the side of the piece, which would require static friction. 2. As the mover pushes the piece of furniture on the dolly across the floor, s/he would probably use only a normal force against the side of the piece (no friction), but there might be some static friction force involved if s/he is pushing at an angle against the piece. 3. As the piece of furniture moves with the dolly under it, it is pressing down on the dolly with a normal force and using static friction to bring the dolly along in the same direction the piece is moving. 4. As the dolly frame presses down on the axle of each wheel, it exerts a normal force on the bearing of the axle. There is probably no friction force involved. 5. As the axle turns within the bearing, there is a combination of static and kinetic friction as the ball bearings turn and slip inside the bearing. 6. As the wheel presses down on the floor, the floor presses up on the wheel with the same amount of normal force. The static friction force from the floor pulls back on the surface of the wheel at the point of contact and causes the wheel to turn.
When the box is moving it experiences a friction force of 20 N to the left or toward the mover What force does the mover need to apply in order to keep the box moving to the right at 1 m s?
Since the box not having any acceleration and is moving with constant velocity the net force on the box is zero. Therefore the mover needs to apply a force of 20 N.

Were Aristotle's predictions of heavenly motion quantitative or qualiative?
I. Aristotle's Theory of Motion • Two basic principles: I. No motion without a mover in contact with moving body. II. Distinction between: (a) Natural motion: mover is internal to moving body (b) Forced motion: mover is external to moving body
