Work = (force) x (distance) = 30 x 9 = 270 joules

The work done on the chair is calculated by multiplying the force applied (30 N) by the distance moved (9 m) and the cosine of the angle between the force and the direction of movement. Since the force is horizontal and the chair is moved horizontally, the angle is 0 degrees. Therefore, the work done is (30 N) * (9 m) * cos(0) = 270 Nm = 270 J.

What happens when someone pushes a chair across the room using newtons second law of motion?
When someone pushes a chair across the room using Newton's second law of motion, the chair accelerates in the direction of the force applied. This acceleration is directly proportional to the force applied and inversely proportional to the mass of the chair. As long as the force is greater than any opposing forces like friction, the chair will continue to accelerate in the direction of the push.
When you sit in a chair what exerts against you?
Assuming that the seat of the chair is horizontal, and you an penis d the chair are stationary, the key forces here are your weight, which is acting vertically downwards on to the chair, and an equal reaction force, or normal contact force, of the chair acting on you. This force acts vertically upwards. You could also include the forces of the air acting on you and vice versa, but this is probably not what you're after.
What is a chair carried on poles called?
A chair carried on poles is called a sedan chair. This type of chair was historically used to transport one person who was carried by a team of bearers.
Why chair can't reproduce?
A chair is an inanimate object.
What are easy chair back covers called?
Easy chair back covers are commonly referred to as chair back protectors or chair back slipcovers. These covers are designed to easily slide over the back of a chair to provide protection and style.
What amount of work is done on a chair that is pushed 89 m across a floor by a horizontal 30-N net force?
The work done on the chair can be calculated using the formula: work = force x distance x cos(theta). Given a net force of 30 N and a distance of 89 m, the work done on the chair is 30 N x 89 m x cos(0°) = 2670 Joules.
What is a geri-chair?
A Geri chair (short for geriatric chair) is an upholstered recliner on wheels that can be pushed around like a wheel chair. It usually has a removable tray.
When you pull a chair across a room your demonstrating?
When you pull a chair across a room, you are demonstrating the transfer of kinetic energy. As you exert force on the chair, it moves across the floor due to the friction between the chair's legs and the floor. This movement involves a conversion of energy from your muscles to the chair's kinetic energy.
Can you give me an example of a sentence using 'on'?
'I pushed the button on'.'I sat on the chair'.

How do you beat the Bridge Crossing game?
Here are the steps:Send across: 1, 3Send back: 3Send across: 8, 12Send back: 1Send across: 1, 6Send back: 1Send across: 1, 3Each number represents the character that will take that many minutes to cross the bridge.
What you pull a chair across a room what force is that?
When you pull a chair across a room, you are exerting a force known as kinetic friction. This force opposes the direction of motion and arises between the chair's legs and the floor surface due to their contact.
How do you cross the bridge on coolmath4kids?
first, take the chair guy and the black guy across the bridge. take chair guy back. make the old lady and the princess go across. make the black guy take the lantern back across. Use the chair guy and the tall "gentleman" to get across the bridge. Chair guy goes back and gets the black guy. It took me 3 years to figure this out. Poor me.
Why is it easier to move a chair with wheels across a floor than chair without wheels?
Friction is what makes moving a chair without castors so difficult.

How do you move the chair on Counterfeit Island?
To "scoot" the chair backward, place your mouse cursor to the right of your player and drag across to the left. This will move the chair left.
What happens when someone pushes a chair across the floor?
When someone pushes a chair across the floor, the force applied in the pushing direction causes the chair to move. Friction between the chair legs and the floor resists the motion, which can create a sound as the chair moves. If the force is strong enough, the chair will accelerate and continue moving until the force is removed or balanced by other forces.
