Aspacecraft is in orbit around jupiter. the radius of the orbit is 2.800 times the radius of jupiter (which is rj = 71,490 km). the gravitational field at the surface of jupiter is 22.00 n/kg. what is the period of the spacecraft's orbit?

T = 1.132 x 10⁴ s

Explanation:

given,

Radius of the orbit = 2.8 times radius of Jupiter

Radius of Jupiter, R_J = 71,490 km

gravitational field at the surface of Jupiter, g_J = 22 N/kg

using Kepler's third law equation

rearranging the equation,

we know,

now,

T² = 1.2829 x 10⁸

T = 1.132 x 10⁴ s

The period of the spacecraft's orbit is equal to 1.132 x 10⁴ s

the force required to move the cart is divided by three or 33.33 n.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
