Determine the centripetal force upon a 40-kg child who makes 10 revolution around the cliffhanger in 29.3 seconds. the radius of the barrel is 2.90 meters

The centripetal force acting on the child is 39400.56 N.

Explanation:

Given:

Mass of the child is,

Radius of the barrel is,

Number of revolutions are,

Time taken for 10 revolutions is,

Therefore, the time period of the child is given as:

Now, angular velocity is related to time period as:

Now, centripetal force acting on the child is given as:

Therefore, the centripetal force acting on the child is 39400.56 N.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
