Work is done when a force is exerted on an object and that force causes the object to move in the direction of the force. If the object moves, then work is being done. The work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.
The juggler is giving kinetic energy to the pin when he moves it with his hand. This energy is associated with the motion of an object.
The electrical energy from the power source moves through the chandelier's wires and is converted into light and heat energy by the bulbs. When the waiter moves the switch to turn on the chandelier, this energy transformation occurs, brightening the ballroom.
When you turn a screw, it exhibits two types of motion: rotational motion, as the screw twists around its axis, and translational motion, as the screw moves either closer or farther away from the surface it is being driven into.
The energy transformation is electrical energy being converted to light energy. When the switch is moved, the electrical energy flows through the chandelier's circuit, causing the light bulbs to glow and illuminate the ballroom.
Hummingbirds are the only birds that can fly backwards.
forwards and backwards

it depends... is it a salt water or fresh water type of fish. if it is a fresh water kind there is something wrong with it but if it is a salt water kind apparently some have been found to swim backwards for no apparent reason.
It is impossible for any bird to fly directly backwards. Unless the wings were put on backwards it wont work, as the wings are designed to propel forward.

Yes it is being done, if the person doing it is doing it as part of a paid job or because they run a business and the letter is needed for the business. If it is being typed for school it may also be considered work, but of a different kind. And from the view of physics, since energy is being expended by the person typing, and perhaps by the machinery being used, work is being done. However, if you are at work and typing a letter to your grandmother, that is not the kind of work you are being paid for and your employer would say work is not being done.
not very much considering there are alot of there kind and not nearly exctinct
no unless your some kind of weirdo
The time for any kind of surgery depends on the situation and on what is being done
Kinetic
It can be read the same way backwards and forwards.
