1. why does the sun have the greatest amount of gravity in our solar system?

2 answers:

6 0

The lighter object orbits the heavier one, and the Sun is, by far, the heaviest object in the solar system. ... Heavier objects (really, more massive ones) produce a bigger gravitational pull than lighter ones, so as the heavyweight in our solar system, the Sun exerts the strongest gravitational pull.

Two satellites are orbiting earth at different altitudes. Which satellite orbits at a higher speed v around earth?

aniked [119]

Answer:

Low satellite has high orbital velocity

Explanation:

let v be the orbital speed of the satellite orbiting at a height h is given by

$v=\sqrt{\frac{GM}{R+h}}$

where, M be the mass of planet, r be the radius of planet and h be the height of planet from the surface of planet.

here we observe that more be the height lesser be the orbital velocity.

So, a satellite which is at low height has high orbital velocity.

Find the frequency, if the amplitude of a 3000g object in simple harmonic motion is 1000cm and the maximum speed of the object i

Oksana_A [137]

Answer:

A = 10 m amplitude

m = 3 kg mass of object

Vm = 5 m/s

w A = Vm where w = omega

w = 2 * pi * f

2 * pi * f 10 = 5

f = 5 / (20 * pi) = .0796 / sec
