Answer:
A compass works by detecting and responding to the Earth's natural magnetic fields. The Earth has an iron core that is part liquid and part solid crystal, due to gravitational pressure. It is believed that movement in the liquid outer core is what produces the Earth's magnetic field.

'Doing work' is a way of transferring energy from one object to another, energy is transferred when a force moves through a distance.
If i explain with formula
Work done (J) = Energy transferred (J)
So more energy, more work done bc u transferred more energy to move the object and doing the work. and if you only use a little of energy, the work done also only a little.
Answer:
33°
Explanation:
We are given;
Speed at which both snowballs are thrown; v = 33.2 m/s
Angle at which snowballs are thrown with respect to the horizontal; θ = 57°
Now,we want to find out the angle at which the second snowball should be thrown in order to arrive at the same point as the first.
To calculate this angle, we will use complementary angle concept.
Now, because the target is in the same place, there will be two launch angles that will make the snow ball to be placed on the target.
The is calculated from;θ1 = 45° - (57° - 45°) = 33°
If the boy outputs enough weight upon the ball in response the ball will move.
