the purpose of using a chemical equation is to know the reactants and products that occur.
reactants=starting material
products=end result

Answer:</h2>
<h2>_____________________________________</h2><h3>DATA:</h3>
Radius of Mercury = =
Mass of Mercury =
Distance Satellite above the surface of the Mercury = d = 265,000m
Gravitational Constant =
<h2>_____________________________________</h2><h3>SOLUTION:</h3>
Since the Satellite is orbiting around the Planet Mercury, due to the centripetal force, and Centripetal force is the force that acts towards the center of the circle, Whereas The gravitational force also acts towards the center of the circle thus we can say that Centripetal force is equal or same as centripetal force. So,
Fg is Given by,
Fc is Given by,
Where,
G is Gravitational Constant
is mass of Planet Mercury
is Mass of Satellite
r(small letter) is the distance between the center of the Planet Mercury and the satellite.
V is velocity of satellite
<h2>_____________________________________</h2>
Now,
r can also be written as,
Substitute the variables,
Simplify the equation,
V = 2814
Approximately,
V = 2800

Answer:
Work done is 12.3 J
Explanation:
We have,
Mass of puck, m = 0.35 kg
Force of friction acting on the puck when it slides is 0.15 N
Distance travelled by the puck is 82 m.
It is required to find the work done on the puck. Finally the puck comes to rest and the force of friction is acting on it. It means the applied force is 0.15 N. Work done is given by
The work done on the puck is 12.3 J.
