Question

2. Answer the following questions.
i) State Kepler's law equal of area.
ii) State Kepler's law of period.
iii) What are the dimensions of the universal
gravitational constant?
Define binding energy of a satellite.
v) What do you mean by geostationary
satellite?
vi) State Newton's law of gravitation.
vii) Define escape velocity of a satellite.​

Answer 1

Answer:

pls mark me brainliest i beg of you for my hardwork and thank it as well

ans to vi) and iii) via photo 1 ans to q 1 and 2 via photo binding energy is given by gmm/2r and is the minimum energy required by a satellite to free from gravitational influence escape velocity of a satellite is the minimum speed required by the satelite to free from earth's gravity a geostationary satelite is a type of satelite that has rotational period equal to earth hence i have given ans to all your doubts

Answer 2

Answer:

Keplers first law

The orbit of an planet is an ellipse with the sun at one of the foci

Keplers second law

The line joining the planet and the sun sweeps equal area in equal intervals of time

Keplers third law

The square of the period of revolution of a planet around the sun is directly proportional to the cube of main distance of the planet from the sun

Newton's law of gravitation

Every object in the universal attracts every other object with the definite force .This force is directly proportional to the product of the masses of two objects and the inversely proportional to the square of the distance between them

Escape velocity

When a body is thrown vertically upward from the surface of the earth the minimum initial velocity of the body for which the body is able to overcome the downwards pool by the earth and can accept the earth forever is called the escape velocity .
