According to my guesses, he should have swung the pendulam bob and noted its time period. In order to observe the effect of mass, he would have repeated the experiment with varied pendulam bobs. Hope this helped!
Answer:
Explanation:
Let us assume that the radius of the wire, r = 0.8 mm = 0.0008 m
EMF of the battery, V = 12 V
Slope of I versus 1/d, m = 600 A-m
The resistance of any material is given by :
d is the length of wire
Since,
So, the resistivity of the material of which the wire is made is .
Answer:
B is a false statement
Explanation:
Because the law of energy conservation state that energy can neither be created nor destroyed
