20 miles = 32186.9 meters
32186.9 / 340 = 94.667352
It will take 94.667 seconds to hear an explosion from 20 miles away.
Answer:
8
Explanation:
(8√2)² = x² + x²
8² × √2² = 2x²
64 × 2 = 2x²
128 = 2x²
64 = x²
x = 8

Answer:
24.07415 rpm
Explanation:
= Coefficient of friction = 0.63
v = Velocity
d = Diameter = 4.9 m
r = Radius =
m = Mass
g = Acceleration due to gravity = 9.81 m/s²
Here the frictional force balances the rider's weight
The centripetal force balances the weight of the person
Velocity is given by
Converting to rpm
The minimum angular speed for which the ride is safe is 24.07415 rpm
Wavelength is measured in various units of distance (mm, cm, m, etc.). Frequency uses hertz, but that is not what the question is asking. Therefore, the answer is false.
