Electric potential on one side of the closed circuit is applied and this causes the electrons to move to a position of lower potential. Imagine this as when you raise an object above the ground and release it. It moves from its higher potential energy position above the ground to its lower potential energy position.
Answer:
<h2>0.66m</h2>
Explanation:
<em>The question is not complete, here is the complete question, also see attached the image.</em>
<em>"A bicycle gear wheel is a disc with 50 ‘teeth’ equally spaced around its edge, as shown. The gear wheel is rotated 10 times each second. A springy strip of metal is vibrated by the rotating ‘teeth’. The metal strip produces a sound of frequency that is equal to the frequency of vibration of the strip. The speed of sound in air is 330ms–1. What is the wavelength of the emitted sound?"</em>
given data
number of teeth= 50
we are told that the gear is rotated 10 times in 1 sec,
hence the frequency of the rotation past the strip is
=50*10
=500Hz
speed of sound= 330m/s
we know that
-----------1
where Vw is the speed of sound,
f is its frequency, and
λ is its wavelength.
λ=Vw/f
λ=330/500
λ=0.66m
This depends on the original mass of the object having its mass doubled and the the original distance before the distance was tripled.
Answer:
The answer is both technician A and B
Explanation:
Possible indication of by the red brake lamp is faulty brake system, since when the brake pedal is pushed normally it is turned on. Hence this indicates a faulty brake system if it is turned on without pushing the brake pedal.
Also the brake light is turned on when ever there is shortage in brake fluid, this signals that there is a possible fault in the braking system.
