Answer: Rock candy is candy made of large sugar crystals. To make rock candy, a supersaturated solution of sugar in water is created and left undisturbed for a few days. The driving force behind crystallization is supersaturation.
The radar device determines the vehicle's instantaneous speed.
I would argue that the purpose of the device is not to determine
whether individuals are driving safely. They only determine whether
individuals are driving within legal speed limits. There's much more
to 'safe' driving than that, but the radar gun can't detect it.
The force of gravity will cause your vehicle to speed up when going downhill, and slow down when going uphill. The energy of motion increases proportionally with the increase in weight, and the energy increases proportionally with the square of the increase in speed. Increase with an increase of your kinetic energy. Gravity decreases your kinetic energy when driving uphill and increases it when driving downhill. Therefore, the force of gravity will make it easier to stop your car if you're going uphill but more difficult to stop your car if you're going downhill.
Answer:
Radius of orbit = 3.992 ×
m
Altitude of Satellite =33541.9× m
Explanation:
Formula for gravitational force for a satellite of mass m moving in an orbit of radius r around a planet of mass M is given by;

Where G = Gravitational constant = 6.67408 × 10-11 
We are given
F= 800 N
m = 320 Kg
M = 5.972 ×
Kg
G = 6.67408 × 10-11 
We have to find radius r =?
putting values in formula;
==> 800 =6.67408 ×
× 320 × 5.972 ×
/ 
==> 800= 39.8576 ×
× 320 / 
==> 800 = 12754.43 ×
/ 
==>
= 12754.43 ×
/800
==>
=15.94 ×
==> r = 3.992 ×
m
==> r = 39920×
m
This is the distance of satellite from center of earth. To find altitude we need distance from surface of earth. So we will subtract radius of earth from this number to find altitude.
Radius of earth =6378.1 km = 6378.1 ×
m
Altitude = 39920×
- 6378.1 ×
