Explanation:
Formula to calculate angular acceleration is as follows.
or,
Putting the given values into the above formula as follows.
=
= 0.326
Thus, we can conclude that the wheel’s angular acceleration if its initial angular speed is 2.5 rad/s is 0.326 .
Answer:
12 m/s
Explanation:
Standing waves are waves that are formed between two fixed points in space, so they cannot propagate, but they are just oscillations about a fixed points. Examples of standing waves are the waves in a string.
The relationship between wavelength, frequency and speed of a wave is given by the wave equation:
where
v is the speed of the wave
f is its frequency
is its wavelength
For the standing wave in this problem we have:
f = 3 Hz is the frequency of the wave
is the wavelength
Solving for v, we find the velocity of the wave:
Answer:
One of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Explanation:
You would get 13.7
mi/51mm=3.5mm/13mm
by solving it you will B13.7mm
