Weight (that's what the 500 N is) = (mass) x (gravity) .
On Earth, gravity = about 9.8 m/s² , so
500 N = (mass) x (9.8 m/s²) .
Divide each side by 9.8 m/s²:
Mass = (500 N) / (9.8 m/s²)
= 51 kg (rounded) .
Answer:
An electric current passing through a coil of wire gives a strong form of magnetism called electromagnetism. When the electric current passes through a single straight piece of wire the electromagnetism is weak.
Explanation:
Absolute dating and relative dating are both used commonly to determine the age of fossils. Absolute dating gives the exact date and chronological order to which the fossil lived. They do this by looking at the surrounding ground and using the carbon to find out how old it is. Relative dating is pretty similar to this except it uses carbon dating which is a way of finding the approximate age of the fossil. They do this by looking at the layers of the earth and making an assumption as to how old it is.

Explanation:
Photovoltaic energy is a clean, renewable source of energy that uses solar radiation to produce electricity. It is based on the photoelectric effect—the emission of electrons when electromagnetic radiation (i.e. light) hits a material.
