A5592 n piano is to be pushed up a(n) 3.79 m frictionless plank that makes an angle of 30.1 ◦ with the horizontal. calculate the work done in sliding the piano up the plank at a slow constant rate. answer in units of j.

10628.87 J

Explanation:

We are given that

Force applied =F=5592 N

Displacement=D=3.79 m

We have to find the work done in sliding the piano up the plank at a slow constant rate.

Work done=

The perpendicular component of force=

Work done =

Hence, the work done in sliding the piano up the plank at a slow constant rate=10628.87 J

explanation:

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
