Question

In July 1994 the comet

Shoemaker-Levy 9 collided with

the planet Jupiter, as scientists had

predicted. To be able to accurately

predict when a comet will collide with a

planet, it is essential to understand-

A. the composition of a planet's

atmosphere

B. the gravitational attraction that

exists between all bodies

C. the attraction of opposite poles of a

magnet to each other

D. the formation of comets

Answer 1

The correct answer is B) the gravitational attraction that exists between all

bodies.

Step-by-step explanation:

Every plant has a gravitational force which extends beyond its atmosphere.

The formula for calculating this gravitational pull is given as follows:

Fg= GMm/r2

`F_(g)` = Force of Gravity

G = Gravitational Constant

M = Mass of the Planet

m = The Comets Mass

r = The distance between the centre of the comet and that of the planet

The force of gravity of the Planet can cause the comet to move faster in it's course towards the planet. This is called centripetal acceleration.
