Velocity is Displacement / Time
In order for Velocity to Accurately get a winner, you should be able to determine the race by looking at <em><u>How Far the competitors are from the starting point in the shortest amount of time
</u></em><u />so the answer should be something like : a 5 mile course from the center of the town heading north to the outskirts of the town
Answer:
i = 0.00077A
Explanation:
Given:
loop radius, r = 3.0 cm = 0.03 m
Area, A = π x r² = π x 0.03² = 0.0028 m²
Magnetic Field, B = 0.75 T
Loop resistance, R = 18 Ω
time, t = 0.15 seconds
Now,
the induced emf is given as:
EMF = - BA/t .......1
Likewise,
EMF = iR.......2
Equate 1 and 2
iR = - BA/t
i = - BA/tR
i = 0.75×0.0028/0.15×18
i = 0.0021/2.7
i = 0.00077A
The answer would be half court I think
