it's zero
Explanation:
it is there is your answer
Answer:
∴Inductance of solenoid A is 
of inductance of solenoid B.
Explanation:
Inductance of a solenoid is
N= number of turns
= length of the solenoid
d= diameter of the solenoid
A=cross section area
B=magnetic induction
= magnetic flux
= Current
Given that, Solenoid A has total number of turns N, length L and diameter D
The inductance of solenoid A is
Solenoid B has total number of turns 2N, length 2L and diameter 2D
The inductance of solenoid B is
Therefore,
∴Inductance of solenoid A is of inductance of solenoid B.
there are three ways by which we can transfer heat from one place to other
1. Conduction
In this method of heat transfer heat can be transferred from one place to other without actual movement of medium molecules. This is possible in solid conducting mediums
2. Convection
Here heat energy is carried away along with the medium molecules where medium molecules can move from one place to other while heat is transferred. It is possible in liquid and gas but not possible in solids
3. Radiation
In this mode of heat transfer we do not require any medium and here heat transferred by electromagnetic waves
So we can feel heat from sun in form of electromagnetic waves and it is the fastest way to transfer the heat also it do not require any medium
Just like the water cycle, rocks undergo changes of form in a rock cycle. A metamorphic rock can become an igneous rock, or a sedimentary rock can become a metamorphic one. Unlike the water cycle, you can’t see the process happening on a day-to-day basis. Rocks change very slowly under normal conditions, but sometimes catastrophic events like a volcanic eruption or a flood can speed up the process. So what are the three types of rocks, and how do they change into each other? Keep reading to find out!
