Answer:
Option A
Up
Explanation:
we can determine the direction of the angular velocity of a rotaing body by using the right hand rule.
The right hand rule says that if you hold the axis with your right hand and rotate the fingers in the direction of motion of the rotating body then your thumb will point the direction of the angular velocity.
Following this, curving the fingers in such a way that they depict motion from the east to north, we can see that our thumb will point upwards. This makes the direction of the angular velocity at that point in time to be up
Answer: Option A: The spots on the balloon move away as the balloon is inflated.
one of the scientific models describes the galaxies are moving apart as the universe is expanding. This expansion theory came from the observation of red-shifted spectrum from all the directions indicating that the galaxies are moving away. This can be understood from the inflated balloon. Initially spots can be marked using a colored pen on the balloon.On inflating the balloon, it would be noticed that the spots on the balloon move away. Actually the position of the spots won't change, but the distance between the spots would expand. This is a good model to explain the expanding universe. The galaxies are neither moving in any random direction nor moving forward. So, rest of the options are not good models to explain the theory.
