"What is the potential energy relative to the water surface of a diver at the top of a 26 m high diving platform? Suppose she has a mass of 35 kilograms."

PE = 8918 J

Explanation:

Formula for potential energy here is;

PE = mgh

Where;

m is mass

g is acceleration due to gravity

h is height

We are given;

m = 35 kg

h = 26 m

Thus;

PE = 35 × 9.8 × 26

PE = 8918 J

your parents i think this could be it

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
