Seasons because the tilt of the Earth's axis causes the sun to hit different spots with more or less light. So if the Northern part of the Earth is tilted away from the Sun, it's winter. But if it's tilted towards the sun, it's summer. Hope that helps!
Answer:
10kgm/s
Explanation:
Momentum = Mass * Velocity (both in standard units)
Momentum = 5 * 2 = 10kgm/s
They ALL do.
Every object with mass has a gravitational field ... just as long as its mass is somewhere between an electron and a supercluster of galaxies.
Gravity and friction would affect the long jumper.
