An automobile of mass 1.46 cross times to the power of blank 10 cubed kg rounds a curve of radius 25.0 m with a velocity of 15.0
Vsevolod [243]

The centripetal force exerted on the automobile while rounding the curve is 1.31\times10^4 N

<u>Explanation:</u>

given that

Mass\ of\ the\ automobile\ m  =1.46\times 10^3 kg\\radius\ of\ the\ curve\ r =25 m\\velocity\ of\ the\ automobile\ v=15m/s\\

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

centripetal\ force=mv^2/r\\=1.46\times10^3\times15^2/25\\=1.46\times 10^3\times 225/15\\=1.31\times 10^4 N

Two competing models attempt to explain the motions and changing brightness of the planets: Ptolemy's geocentric model and Coper
Ivanshal [37]

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.
