.5 The number of revolutions made by a wheel travelling over a fixed distance varies
radius of the wheel./ A wheel of 12-inch radius makes 100 revolutions to travel a certain distance
How many revolutions would a wheel of 16-inch radius require to travel the same distance
Answers
75 Revolutions has to be made by wheel of 16 inch to cover the same distance as by a wheel of 12 inch radius in 100 revolution
Step-by-step explanation:
The number of revolutions made by a wheel traveling over a fixed distance varies inversely proportional to radius of the wheel
Number of Revolution ∝ 1/Radius of wheel
N = k/ R
NR = k
N = Number of revolutions
k - Constant
R = Radius of Wheel
A wheel of 12-inch radius makes 100 revolutions to travel a certain distance
=> 100 * 12 = k
=> 1200
revolutions a wheel of 16-inch radius require to travel the same distance
N * 16 = 1200
=> N = 75
75 Revolutions has to be made by wheel of 16 inch to cover the same distance as by a wheel of 12 inch radius in 100 revolution
