resistance increases with the increase in length of the wire and decreases with the increase in area of cross section
Sorry- no one answer- the area will vary depending on the length of the sides.
There is only one basic shape for an equilateral triangle. The area can only vary as the length of the sides vary.
The dimensions of a rectangle with an area of 400 square meters can vary, as multiple pairs of length and width can produce this area. For example, if the length is 20 meters, the width would be 20 meters (making it a square). Alternatively, if the length is 40 meters, the width would be 10 meters. Thus, any combination of length and width that multiplies to 400 will satisfy the area requirement.
The frequency of a pendulum varies with the square of the length.
Earthworms vary greatly in their length.
