What is the potential energy of a bowling ball as it sits on a 40 meter tall building

784 J

Explanation:

The formula for potential energy is PE = mgh, where m is the object's mass, g is the gravitational constant (on earth, it is 9.8 m/s/s) and h is the height from the ground.  Using the given information,

m = 2 kg

g = 9.8 m/s/s

h = 40 meters

Plug in the given information into the formula for potential energy.

PE = (2)(9.8)(40) = 784 J

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
