Answer:
Part A W= 2772J
Part B = -2.772J
Explanation:
Work = force × distance
Part A when you move from lower to upper level
= mgh
= 63× 4.4×10
=2772J
=2.772KJ
Part B
When you move from upper to lower
The acceleration due to gravity becomes negative -10m/s^2
Therefore Work =-2772KJ
Work = -2.772KJ
Well it would tell us the number of neutrons and protons in the nucleus so i would assume the number of energy levels.
Ok. what rock tho. cause all the rocks i have is all bleh and boring
Answer:
When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. This is force is called as the action force. The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.
Answer:
Transactional process
Explanation:
Because communication involves two or more people acting in both sender and receiver roles and because their messages are dependent on and influenced by those of their partner means that communication is a transactional process i.e. a give and take process.
If the sender relays a message and the receiver does not reply or reply not taking cognizance of the sender's message, communication has not taken place.
For example, if consider this.
Sender: How old are you?
Reciever: My Cat is Red.
The response of the receiver is not in tune with the sender and so communication has not taken place.
