Asatellite orbits earth at an altitude of 350 km. what is its orbital period? a) 1.1 min b) it can not be determined without the satellite's mass. c) 65 min d) 91 min e) 1440 min

The orbital period is 91 min.

(d) is correct option.

Explanation:

Given that,

Altitude = 350 km

We know that,

Radius of earth

Mass of earth

We need to calculate the orbital period

Using formula of orbital  period

Where,

G = gravitational constant

M = mass of earth

Put the value into the formula

Hence, The orbital period is 91 min.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
