The clicker emits EM (electromagnetic) wave which travels at the speed of light, that is
v = 3 x 10⁸ m/s
The frequency is
f = 900mHz = 9 x 10⁸ Hz
Because velocity = frequency * wavelength, the wavelength, λ, is given by
fλ = v
λ = v/f
= (3 x 10⁸ m/s) / (9 x 10⁸ 1/s)
= 1/3 m
Answer: 1/3 m
Answer: Sound Energy
Sound Energy
Explanation:The vibrations produced by the ringing bell causes waves of pressure that travel or propagate through the medium that is air. Sound energy is a form of mechanical energy that is generally associated with the motion and position of the ringing bell.
<span>Energy is neither lost nor gained as it transforms from chemical, to heat, to mechanical energy.</span>
Explanation:
Let x = distance of 
from the fulcrum and let's assume that the counterclockwise direction is positive. In order to attain equilibrium, the net torque 
about the fulcrum is zero:
Solving for <em>x</em>,
