Given: g = 6.67259 × 10−11 n m2 /kg2 . a 438 kg geosynchronous satellite orbits a planet similar to earth at a radius 1.94 × 105 km from the planet’s center. its angular speed at this radius is the same as the rotational speed of the earth, and so they appear stationary in the sky. that is, the period of the satellite is 24 h . what is the force acting on this satellite? answer in units of n.

449.37412 N

Explanation:

G = Gravitational constant = 6.67259 × 10⁻¹¹ m³/kgs²

m = Mass of satellite = 438 kg

M = Mass of planet

T = Time period of the satellite = 24 h

r = Radius of planet =

The time period of the satellite is given by

The gravitational force is given by

The force acting on this satellite is 449.37412 N

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
