The centripetal force exerted on the automobile while rounding the curve is 
<u>Explanation:</u>
given that

Objects moving around a circular track will experience centripetal force towards the center of the circular track.

Power (watts) = work done (joules) ÷ time (seconds)
power (watts) = 1000J ÷ 20s
power (watts) = 50w
Answer:
I'm sure its transverse, longitudinal and surface
Explanation:
sorry if I'm wrong
Geocentric:
-The model is Earth centered
-Retrograde motion is explained by epicycles.
Heliocentric:
-This model is Sun-centered.
-Retrograde motion is explained by the orbital speeds of planets.
Both geocentric and heliocentric:
-Epicycles and deferents help explain planetary motion.
-Planets move in circular orbits and with uniform motion.
-The brightness of a planet increases when the planet is closest to Earth.
