Answer:
Explanation:
We are given that
Mass of spherical shell,
=1900 kg
Mass=
Radius of shell=r=5 m
Distance between two masses=r=5.01 m
Because distance measure from center .
Gravitational force
Using the formula
Hence,the gravitational force =
Answer: a
Explanation: it talks about how they live without that much light
To reach a vertical height of 13.8 ft against gravity, which has an acceleration of 32 ft/s^2, the required vertical speed can be calculated from the equation:
vi^2 - vf^2 = 2*g*h
Given that it has vf = 0 (it is not moving vertically at its maximum height), g = 32, and h = 13.8, we can solve for vi:
vi^2 = 29.72 ft/s
This is only its vertical speed, so this is equivalent to its original speed multiplied by the sine of the angle:
29.72 ft/s = (v_original)*(sin 42.2<span>°</span>)
v_original = 44.24 ft/s
Converting to m/s, this can be divided by 3.28 to get 13.49 m/s.
The sum of all forces applied to the object = (mass) x (acceleration)
The sum of all forces applied to the object = (30) x (15)
= <u>450 newtons</u>, in the direction of the acceleration.
