Answer:
As the axial tilt increases, then the seasonal contrast increases so that winters are colder and summers are warmer in both hemispheres. The northern hemisphere is tipped away from the Sun, producing short days and a low sun angle. What kind of effect does the earth's tilt and subsequent seasons have on our length of daylight (defined as sunrise to sunset). Over the equator, the answer is not much.
C. magnetic forces act at a distance
Explanation:
Since he was able to drag the keys along the table by moving the magnet, it shows that magnetic forces acts a distance.
Magnetism is a property exhibited by a wide range of materials.
Around a bar magnet, there are field forces in which the forces of the magnets are felt.
- Magnetic forces are non- contact forces. They don't need to be together to exert their force.
- This is why magnetic forces act at a distance.

Answer:
In order to calculate the work that the spike did, you have to respect the following equation:
WORK = FORCE X DISPLACEMENT X COS (0)
Explanation:
Work is measured in joules, and is the amount of energy a body needs to make a certain force over a certain distance.
In the case of this bird we would be calculating with the equation written up in the previous item the work that said animal would do to grind a seed.
