A. 5 kg pizza is sitting on a kitchen counter 1.5 m high. How much potential energy does the pizza have?

73.5J

Explanation:

Given that,

Mass of pizza (m) = 5 kg

Height of kitchen counter (h) = 1.5m

Potential energy of pizza (PE) = ?

Potential energy is the energy possessed by an object at rest. And it depends on the mass (m), height (h), and acceleration due to gravity (g). Use the value of g, which is 9.8 m/s²

PE = mgh

PE = 5 kg x 9.8 m/s² x 1.5 m

PE = 73.5 J

Thus, the pizza has 73.5 joules of potential energy.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.
