<span> Using conservation of energy
Potential Energy (Before) = Kinetic Energy (After)
mgh = 0.5mv^2
divide both sides by m
gh = 0.5v^2
h = (0.5V^2)/g
h = (0.5*2.2^2)/9.81
h = 0.25m

Weight = Mass * gravity
= 1470* 9.8 = 14406 N ≈ 14,400 N
I think it's (ASTRONOMICAL UNIT)
Explanation:
It is used to compare the distances of other bodies in the Solar System, such as the Sun, the planets, comets, and asteroids.
Answer:
2. electromagnets can be made stronger by adding more coils to the solenoid.
3. electromagnets can be made stronger by increasing the strength of the electrical source.
Explanation:
Electromagnets are not permanent, they act as magnets when current runs through its coils. They can be stronger by increase the current that goes through the coil surrounding them,. This can be done two ways: 1) increasing the actual current intensity, or 2) increasing the number of coils that wrap around them.
