Answer: True.
Explanation:
You would be able to visualize the basketballs height going up and when it sinks down into the hoop.
Answer:
E) be two times larger.
Explanation:
As we know that the relation between the resistance and the resistivity of the wire is given as:
where:
resistivity of the wire
length of wire
area of wire
resistance
Now, when the length of the wire is four times the initial length then for the resistance to remain constant:
where:
area of the new wire
we know that area of the cross section of wire is given as:
Hence the radius must be twice of the initial radius for the resistance to be constant when length is taken four times.
