Explanation:
Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity v and has the magnitude ac=v2r;ac=rω2 a c = v 2 r ; a c = r ω 2 .
Once the car is on top of the hill it contains potential energy witch means it is storing enough energy to slide the hill until acted on. Once the car moves and slides down the hill it creates kinetic energy witch means it's in motion. The car then turns the kinetic energy into mechanical energy witch means it's working. I'm not sure if that helped but good luck!
The two competing forces that keeps earth orbiting the sun is gravity and inertia
Answer:
30.7m
Explanation:
You can use the following equation:
ρ = R * 
Where ρ is the resistivity, R is the resistance, S is the Cross-sectional Area and l is the length of the wire.
We issolate l in the equation and solve with the data we have:
l = R * 
= 3.25 Ω * 
l = 30.7m
