Answer:

Explanation:
The process during which pressure remains constant is called an isobaric process.
Answer:
The Height of a pyramid is 4r.
Explanation:
Explanation is in the following attachments
Step up transformer is a device which is used to step up the voltage which is input with some value.
This is based upon the principle of mutual inductance and in this the voltage input and voltage output is different because of number of turns.
Here if ideal transformer is given then power input and power output of the transformer must be same as there is no power loss in ideal transformer.
So we can write

here
= 73.37 A
= 4623 V
= 105033 A
now using above equation we will have

solving above we will have

Answer:
There would be more hours of sunlight at the equator
