The potential energy (P.E) of X at r is less than P.E at s.

The total energy (T.E) of Y is less than total energy (T.E) of X.

The PE of Y at v is greater than the PE of Z at c.

The speed of Y at i is .greater than that at v.

The kinetic energy (KE) of z at u is less than that at n.

The PE of Y at s is less than the PE of X at c.

The PE of X at c is less than the PE of Z at c.

The PE of X at c is less than the PE of Z at c.

<h3>PE of X at r  and at s</h3>

The potential energy (P.E) of X at r is less than P.E at s due to greater displacement at s.

<h3>TE of Y is .... the TE of X</h3>

The total energy (T.E) of Y is less than total energy (T.E) of X because X has greater displacement from the planet.

<h3>PE of Y at v is .... the PE of Z at c</h3>

The PE of Y at v is greater than the PE of Z at c due to greater displacement at v.

<h3>Speed of Y at i is .... that at u</h3>

The speed of Y at i is .greater than that at v because i is closer to the planet than v.

<h3>KE of Z at u is .... that at n</h3>

The kinetic energy (KE) of z at u is less than that at n because n is closer to the planet and will have greater velocity.

<h3> PE of Y at s is .... the PE of X at c</h3>

The PE of Y at s is less than the PE of X at c, because position c has greater displacement.

<h3>The TE of Z is .... the TE of X</h3>

The TE of Z is greater than the TE of X due to greater displacement of Z from the planet.

<h3>The PE of X at c is .... the PE of Z at c</h3>

The PE of X at c is less than the PE of Z at c due to greater displacement of Z from c.

vladimir2022 [97]

Answer:

f = 0.4 Hz

Explanation:

The frequency of rotation of an object in order to achieve required centripetal or radial acceleration, can be found out by using the following formula:

f = (1/2π)√(ac/r)

where,

f = frequency of rotation = ?

ac = radial acceleration = 34.1 m/s²

r = radius = length of beam = 5.55 m

Therefore,

f = (1/2π)√[(34.1 m/s²)/(5.55 m)]

<u>f = 0.4 Hz</u>
