When force is acted on an object, it will move even at rest.
Answer:
486 of cell membranes
Explanation:
one cell membrane has 7*10^-9m as the height
So, by dividing 3.4 with 7*10^-9 you will get the number of cell require to form the height.
3.4/(7*10^-9)=485.71
because we can't have decimal number of cell we would round it into three significant figures, 486.
The statement: “According to Faraday's law, voltage can be changed by moving magnets away from the coil of wire.”, is true. Any type of movements done (away, into or out, toward, rotation, etc.) on the magnetic environment would always generate a voltage. In Faraday’s law, it is clear that there are different ways on how to generate a voltage.
No it cannot because you would have to test it over and over again to make sure it was correct the first time.
Answer:
Option A
Explanation:
The correct answer is Option A.
At room temperature, the resistance is equal to 100 ohms.
When the temperature is reduced to 77 K from room temperature, change in the resistance is very less.
The temperature coefficient of the resistivity of most of the metal is small for the metals which are approximately equal 0.01 /K.
hence, Change is only slightly.
