Answer:
Explanation:
The star is revolving the black hole like earth revolves around the sun .so time period of rotation T is given by the following relation
T² = 
, R is distance between black hole and star , M is mass of black hole
Given T = 4.8 hours
4.8² =
Using the same equation for earth sun system
24² = 
, Ms is mass of the sun and 50R is distance between the sun and the earth .
Dividing the equation
= 
= 2x 10⁻⁴
Well 0 because if you multiply anything by 0 it will conclude to 0 and number 2 is the same answer hope you got it
Earth Spheres. Earth's Spheres. Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air).
Answer:
See below
Explanation:
East components are 10 and 12 cos 30 = 20.392 m/s
North component = 12 sin 30 = 6 m/s
Resultant velocity = sqrt ( 20.392^2 + 6^2) = <u>21.26 m/s </u>
direction arc tan (6/20.392) = <u>16.4 degrees N of east </u>
Answer:
C) 8.0 N
Explanation:
F=m*a
