You move the decimal to right behind the first significant digit and the exponent on the 10 is how many places you moved that decimal. You can type it into a calculator to check it as well if you're not sure.
Answer:
gravitational potential energy of 10 kg mass is 122.625 J
Explanation:
Gravitational Potential energy gain is given as

here we know that
m = 10 kg
h = 1.25 m
now from above formula we have


So gravitational potential energy of 10 kg mass is 122.625 J
Answer:
When a heavy football player and a light one run into each other, does the lighter player really exert as much force on the heavy player s the heavy player exerts on the light one. Yes. The interaction between the two players, the force each exerts on the other have equal strength.
The kinetic energy is transferred to thermal energy through friction
