Answer:
94.1 m
Explanation:
From Coulombs law,
F = Gm1m2/r²................... Equation 1
where F = force, m1 = first mass, m2 = second mass, G = universal constant, r = distance of separation.
Make r the subject of the equation,
r = √(Gm1m2/F)................. Equation 2
Given: F = 7×10² N, m1 = 15×10⁷ kg, m2 = 62×10⁷ kg,
Constant: G = 6.67×10⁻¹¹ Nm²/kg²
Substitute into equation 2
r = √( 6.67×10⁻¹¹×15×10⁷×62×10⁷/7×10²)
r √(886.16×10)
r √(88.616×10²)
r = 9.41×10
r = 94.1 m.
Hence the distance of separation = 94.1 m
Conservation of momentum
Pinitial=Pfinal
MaVa+MbVb=MtotalVfinal
(5.5)(9)+(5.5)(5)=(5.5+5.5)V
49.5+27.5=11V
77/11=V
7m/s=V

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:compound is a poly element pure substance
Explanation:
It made up of two or more elements.
It can be broen down into simpler units
It is a stretch of the atmosphere ranging from the upper mesosphere to the lower parts of the thermosphere. It’s useful to us in radio communication.
