Answer:
Explanation:
Single-phase transformers can operate to either increasing or decreasing the voltage applied to the primary winding. When a transformer is used to “increase” the voltage on the secondary winding with respect to the primary, it is called a Step-up transformer
The phase of matter is the Solid Phase.

Answer:
The length is 
Explanation:
From the question we are told that
The length of the hand is 
The angle at the hand is held is 
Generally resolving the length the length of the hand to it vertical component we obtain that the length of the shadow on the vertical wall is mathematically evaluated as
substituting values
