4p A teacher pushed a 98 N desk across a floor for a distance of 5 m he
exerted a horizontal force of 20 N for four seconds. 1) How much work
was done ? 2) How was his power ? 3) what is meant by energy = 3J*

You can get w =Fxd 20Nx5m w=100N energy= w÷t 100N÷4s E=25J 3 you can apply 3J in one second

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
