A 36kg boxes lifte onto a shelf 1.5m hight calculate the total work done​

m=36kg

h=1.5m

f=36×10

=360N

w=f×d

=360×1.5

=540N/M²

Explanation:

mass is 36 kg

height is 1.5m

to find force applied we need to multiply mass and gravity which is 10

we get force as 360N

to get workdone we need to multiply force and distance in our case it is height

then we get workdone as 540N/M²

540N/m²

Explanation:

m=36kg

h=1.5

g=10m/s²

W=36×1.5×10

=540N/m²

the answer is a. at the equator

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
