w=m x g x d
On earth: Potential energy = mgh so: 2kg * 9,81m/s^2 * 5m = 98,1 Joule
Well obviously it depends on the mass being lifted, which is the elevator itself, the people in it, and their luggage if any. If the height of one floor is say 3 meters, the amount of energy used will be M x 9.81 x 3 Joules. M=mass in kg, 9.81 = the gravitational acceleration in meters/sec2. Let this energy be E Joules. 1 Joule = 1 watt.sec, so we have E watt.secs, then you can scale this to KWh (kilowatt.hours), and so get a figure for the amount of electricity used, then multiply this by the cost per KWh. Taking a figure to get the ball park area, I would guess the elevator and 4 people plus luggage at 2000 kg. Then E = 58,860 Joules = 58,860 watt.secs = 0.01635 kilowatt.hours. (3600 seconds in 1 hour). So it is a small amount of electricity and a small amount of money, the exact amount will depend on what your electricity costs per unit (one unit is usually 1 kilowatt.hour)
A square meter is a unit for an area. If you have a room that is 3 meters by 4 meters, it has a floor area of 3x4=12 square meters. This unit can not be converted to regular meters because they measure two different sort of things.
Have you access to the floor above it? if you do, try to life some floorboards and see what you can find. If the ceiling is the bottom of the attic, find a way in and check out the pipes. If you can't access floor above, ask whoever lives there to have a look for you.
The correct sitting position: Your arms should be resting parallel to the floor, your legs should be in the same position and your feet should be flat. Your back should be against the chair, and your shoulders should be back (but not lifted or hunched).
The work done is equal to the change in potential energy, which can be calculated as (mass x gravity x height). Plugging in the values: (200 kg x 9.8 m/s^2 x 5 m) = 9800 J. Therefore, 9800 joules of work are done when the box is lifted 5 meters above the floor.
The work done can be calculated using the formula: Work = force x distance. In this case, Work = 20 N x 5 m = 100 joules. Therefore, 100 joules of work are done when a 20 newton box is lifted 5 meters off the floor.
100
The work done is calculated by multiplying the force applied with the distance moved in the direction of the force. In this case, the work done would be 100 joules (20 N * 5 m).
2,088 J
The idea here is to multiply the force by the distance.
GPE = m*g*h = 294 Joules.

An undersea volcanic formation that doesn't rise 1000 meters above the surrounding sea floor is called a seamount.
The work done is stored as potential energy of the box P=Mgh F=Ma (a=g) F=Mg h=5m Therefore the work done is 20*5 = 100 joules -----------------------------------------------------------------------------------------------------

Seamounts are undersea mountains that rise 1,000 meters above the sea floor.
