As long as the moon orbits the Earth in the same way, the phases will be the same.
Answer:
The two chairs and those sitting on them will move in nearly opposite directions at almost the same speed (assuming that the wheels can only move into two directions - front or back and assuming that the weight of both people are almost the same)
Explanation:
Newton's Third Law states that If an object X exerts a force on object Y, then object Y must exert a force of equal magnitude and opposite direction back on object X.
In other words, when force is applied from source A at B and in direction of B, B also simultaneously returns the force on B and in the direction of B.
This law applies when we jump off the ground when a rocket takes off from the earth into space, etc.
While standing, the body pushes on the earth with a force equal to its own weight. If the ground underneath the body does not meet that force in an equal and opposite direction, both standing on the earth will fall into the earth, with the earth caving underneath it.
You can see why it is important to have a strong foundation for a building and why the depth and strength of the foundation will depend on how much weight is going on it.
Cheers!
Answer : The velocity of an electron is, 
Explanation :
According to de-Broglie, the expression for wavelength is,
and,
where,
p = momentum, m = mass, v = velocity
So, the formula will be:
.............(1)
where,
h = Planck's constant = 
= wavelength = 
m = mass of electron = 
v = velocity of electron = ?
Now put all the given values in formula 1, we get:
Thus, the velocity of an electron is,
20 degrees F! 0 degrees C is equivalent to 32 degrees F, so 20 degrees F is colder.
Kinetic energy. thermal energy (a low form of energy ) is a form of kinetic energy as it is produced as a result of motion of particles either if they vibrate at their position or they move along longer paths. Motion produces friction or resistance which leads to excitation and thus the heat is produced. The higher the motion of the particles, the higher would be the thermal energy.
