The temperature will be the pressure of 130 ka
Answer:
Explanation:
According to the <u>Third Kepler’s Law</u> of Planetary motion:
(1)
Where;:
is the period of the satellite
is the Gravitational Constant and its value is
is the mass of the Earth
is the semimajor axis of the orbit the satllite describes around the Earth (as we know it is a circular orbit, the semimajor axis is equal to the radius of the orbit).
On the other hand, the orbital velocity
is given by:
(2)
Now, from (1) we can find
, in order to substitute this value in (2):
(3)
(4)
(5)
Substituting (5) in (2):
(6)
(7) This is the speed at which the satellite travels
Answer:
y = 2.196 m
Explanation:
Mass, m = 76 kg
distance from axis of rotation, x = 0.38 m
Second Force, F = 129 N
moment arm of the second force, y = ?
Now, equating moments for the equilibrium
So,
m g × x = F x y
76 x 0.38 x 9.81 = 129 x y
y = 2.196 m
Hence, the length of the moment arm is equal to 2.196 m.
