Explanation:
The gravitational force exerted on the satellite is called the centrifugal force, the force keeping it orbiting to the planet. Its formula is F= mass times the square of the velocity all over the radius.Thus,
F = 2400 * 6670^2 * (1/8.92x10^6)
F = 11,970 N
I hope I was able to help you. Have a good day.
Explanation:
It is given that,
Height of the object, h = 17 cm
Object distance, u = -75.5 cm
Focal length of the concave mirror, f = -39 cm
We need to find the height if the cup's mirror image. Let v is the image distance. Using mirror's equation as :
v = −80.67 cm
Let h' is the magnification of the mirror. The magnification of mirror is given by:
h' = −18.16 cm
So, the image of cup is 18.16 cm tall and it is inverted. Hence, this is the required solution.
