Answer:
That people are motivated by a series of five universal needs.
Explanation:
Answer:
The momentum of block B = 27 Kg m/s
Explanation:
Given,
The initial momentum of block A, MU = 15 Kg m/s
The final momentum of block A, MV = -12 Kg m/s
Consider the block B is initially at rest.
Therefore, the initial momentum of block B, mu = 0
According to the laws of conservation of linear momentum, the momentum of the body before impact is equal to the momentum of the body after impact.
<em> MU + mu = MV + mv</em>
15 + (0) = (-12) + mv
mv = 15 + 12
= 27 Kg m/s
Hence, the momentum of the block B after impact is, mv = 27 Kg m/s
To solve this problem we will apply the energy conservation theorem for which the work applied on a body must be equivalent to the kinetic energy of this (or vice versa) therefore
Here,
m = mass
= Velocity (Final and initial)
First case) When the particle goes from 10m/s to 20m/s
Second case) When the particle goes from 20m/s to 30m/s
As the mass of the particle is the same, we conclude that more energy is required in the second case than in the first, therefore the correct answer is A.
I believe the answer is:
~D. Very dusty irregular galaxy.
Hope this helps!!!
Scientists think the most likely reason is that it was heated by tidal forces from Jupiter.
<h3>What is Tidal force?</h3>
This is known as the gravitational effect that stretches an object along the line towards the center of mass of another object as a result of gradient in gravitational field from the other body.
The moon Ganymede having a magnetic field, indicating that its interior was at least partly melted and warm was however as a result of tidal forces from Jupiter which caused the heating.
