A carbon resistor is to be used as a thermometer. On a winter day when the temperature is 4.00°C, the resistance of the carbon r esistor is 217.7 Ω. What is the temperature on a spring day when the resistance is 215.1 Ω? Take the temperature coefficient of resistivity for carbon to be α = −5.00×10^−4C^-1
1 answer:
Answer:
28 degree C
Explanation:
We are given that
We have to find the temperature on a spring day when resistance is 215.1 ohm.
We know that
Using the formula
Hence, the temperature on a spring day 28 degree C.

Answer:
The question is wrong Since if you apply Force on 0.0m²It would mean That the pressure exerted=F/A=F/0
An since we can't divide a number by 0, the question is wrong
Answer:
Explanation:
When top block is just or about to slide on the lower block then we can say that the frictional force on it will be maximum static friction
So we will have
now for the Net force on two blocks to move together
