Answer:
P = 4000 [W]
Explanation:
In order to solve this problem, we must first determine the work, which is defined as the product of force by distance.
W = F*d
where:
W = work [J] (units in Joules)
F = force = 1000[N]
d = distance = 2 [m]
W = 1000*2
W = 2000 [J]
And power is defined as the relationship between work and the time in which the work is done.
P = W/t
P = power [W] (units of watts)
t = time = 0.5 [s]
P = 2000/0.5
P = 4000 [W]
Answer:
if they are different side they attract
if they are the same side they oppose each other ( don't go together)
