Suppose we know nothing about magnetic field but that magnets have two poles. Suppose we have three magnets A, B, and C each with two poles so A1, A2, etc. Now we do an experiment. We put A1 in front of B1 and they attract each other then we do this between A1 and C1 and they attract each other too. Now if same poles were to attract each other then A1, B1, and C1 should have been the same and B1 and C1 should also attract each other but then we see they don't.

Which example best demonstrates how unbalanced forces change the speed of an object's motion?
exis [7]

I don’t see a picture but unbalanced forces could be two boys pushing with a combined force of 400 Newton’s but the surface of what the box is laying on being 600 meaning since the ground is creating a higher force in the form of friction it will slow the boys down. When forces are unbalanced it means that the object can not be still or moving at a constant speed  when one force is greater by a significant amount the object either slows quickly or accelerates fast depending on which factor is greater.

Leokris [45]

Answer:

The work done on the gas is equal to the area under the curve pv diagram w = area of triangle = 1/2 (base)(height) = 1/2 (BC)(Ac) = 1/2 (3v - v)(3p - p) = 1/2 (9 vp - 3 vp - 3vp + vp) = 4 vp/2 W = 2 vp
