Please help if you know the answer A magnet exerts a force, but you can't see it.
Select True for each example that provides evidence that this is true; select False if the example does not
provide the needed evidence.
A paper clip moves toward a magnet when the two objects are about 2 cm apart.
O False
True
Sometimes you cannot push two magnets together to make them touch.
True
O False
A magnet is placed on an aluminum pan; when you hold the magnet only, the pan falls to the floor.
O True
False
Iron filings on a plate move into a distinct pattern when gently shaken above a magnet.
O False
O True

The masses of the objects and their densities

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

The answer is -6hope this
