Suppose the diver at the top of a 9 m high platform has a mass of 50.0 kg. calculate her potential energy relative to the ground. answer in joules.

For the purpose we will use the following equation for potential energy:

U = m * g * h

In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth).

When we plug values into the equation, we get following:

U= 50kg * 9.8 N/kg *9m = 4410 J

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
