If it takes you 10 seconds to move a chair 5 meters across the floor, using a force of 2 Newtons, how much power did you put out?

1watt

Explanation:

Given parameters:

Time  = 10s

Distance  = 5m

Force  = 2N

Unknown:

Power  = ?

Solution:

Power is defined as the rate at which work is being done by a body.

  Power  =  

Work done  = Force x distance  = 2 x 5  = 10J

So;

    Power =   = 1watt

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
