Answer:
gear is part of vehicle.it helps.
Centripetal acceleration is the force acting on the body who's moving in a circular motion. It is still a force, which according to Newton's Second Law of Motion,
F = ma
F = (70 kg)(2)(9.81 m/s²)
F = 1373.4 N
<em>Thus, the answer is B.</em>
Answer:
e. 425.9 Hz
Explanation:
The computation of the frequency is being played by the out-of-tune key is shown below;
Given that
Δf1 = x - 349.2 = 76.7.........(1)
Δf2 = 440 - x = 14.1......(2)
Now solve (1) and (2)
(440 - x) - x + 349.2 = 14.1 - 76.7
789.2 + (-2x) = -62.6
x = 425.9 Hz
Hence, the frequency is being played by the out-of-tune key is 425.9 Hz
Therefore the option e is correct
It depends on speed because it is a part of a car
