Answer:
Mass of Jupiter = 4.173×10^15kg
Explanation:
Using Kepler's 3rd law, it states that the orbital period T is related to the distance,r as:
T^2 = GM/4 pi × r^3
Where G = universal gravitational constant
r = radius
M = masd of jupiter
Rearranging the formular to make M the subject of formular
T^2 × 4 pi = G M × r^3
(T^2 × 4 pi) / (G× r^3) = M
(1.24^2 × 4 × 3.142) /(6.672×10^-11)(4.11×10^8)^3
M = 19.32 /6.672×10^-11)(4.11×10^8)^3
M = 19.32 / 4.63 ×10^15
M = 4.173×10^15kg
When the child is moving, he/she has kinetic energy. For just a brief second before they move the other way, the child is not moving, but they have gravitational potential energy.
The child may need a push from time to time because friction with the air causes loss of energy.
The force will be 4 times smaller.
Not sure if this is right but I think it’s TRUE sorry if it’s wrong....
Answer:
Angular velocity, 
Explanation:
The mass of the skater, M = 74.0 kg
Mass of each arm, 
( since it is 13% of the whole body and each arm is considered)
Mass of the trunk, 
Total moment of Inertia = (Moment of inertia of the arms) + (Moment of inertia of the trunks)
The final moment of inertia of the person:
According to the principle of conservation of angular momentum:
