Acar goes around a curve at 20. m/s. if the radius of the curve is 50 m, what is the centripetal acceleration of the car? *

Given that,

Velocity , V = 20 m/s

Radius of curve, r = 50 m

Centripetal acceleration, ac = ?

since,

ac = V²/ r

ac = 20²/50

ac = 8 m/s²

The centripetal acceleration of car is 8 m/s².

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
