A 5 kg block is sitting at the top of a hill that is 30 m high. What is the potential energy of the block

1470N

Explanation:

The potential energy is the energy at rest, due to the positioning of the object. Potential energy and kinetic energy both makes up the mechanical energy. Potential energy can be calculated using the formula: P.E = mass (m) × acceleration due to gravity (g) × height (h) i.e. P.E= mgh

In this question involving a sitting block, we have its mass (m) to be 5kg and height (h) to be 30m. The acceleration due to gravity (g) is a constant with value 9.8m/s^2.

Hence, with these three values, we say;

P.E = 5 × 30 × 9.8

P.E = 1470N

the match lol

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
