The radius of Mercury's orbit is r = 5.79 x 1010 m and its orbital period is T=88 days. What is the
magnitude of the orbital velocity for the planet around the sun, assuming a circular orbit?
A.7.21 x 103 m/s
B.8.45* 104 m/s
C.4.79 x 104 m/s
D.5.32 x 104 m/s
Higher the mass will cause more friction which will make its temperature higher and it would also need more kinetic energy to move at a higher speed<span />
Answer:
co2 would be the best answer and because i just took this
Explanation:
Answer:

Explanation:
Capacitance C is given by

A= area of capacitor cross section
d= distance
therefore,

A_1= πR^2
d_1= d

A_= π(2R)^2
d_2 = 2d

threfore

and

also we know that E= V/d
⇒
⇒
= A_1/A_2=
=4
therefore,
