Question

b) List two factors affecting resistance.
c) Sanjay completes one round of a square jogging track, in 5 min.
Calculate his average speed if each side of the track is 150 min
length​

Answer 1

Answer:

b) 1. Type of material

2. Length of conductor

3. Width of conductor

4. Temperature of Conductor

c) Perimeter of square = 4a

a = 150m

Perimeter = 4×150

= 600m

Average speed = S1+S2/t1+t2

= 600m/(5×60) seconds

= 10/5

= 2m/s
