A wave looses its power as it comes to shore because it gets less deeper every second it gets closer to shore
the answer is earth for the first one and sun for the second one
Answer:
C. All waves have the same speed.
Explanation:
Wave equation is given as;
V = fλ
where;
V is the speed of the wave
f is the frequency of the wave
λ is the wavelength
The speed of the wave depends on both wavelength and frequency
The speed of the electromagnetic waves in a vacuum is 3 x 10⁸ m/s, this also the speed of light which is constant for all electromagnetic waves.
Therefore, the correct option is "C"
C. All waves have the same speed.
Answer:
<h2>500 J</h2>
Explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
GPE = 5 × 10 × 10
We have the final answer as
<h3>500 J</h3>
Hope this helps you
Answer:
29.76245 rad/s², -117.80972 rad/s²
28.2743 rad/s
3.95833
Explanation:
= Final angular velocity
= Initial angular velocity
= Angular acceleration
= Angle of rotation
t = Time taken
Equation of rotational motion
Angular acceleration during speed up is 29.76245 rad/s²
Angular acceleration during spin down is -117.80972 rad/s²
Angular speed is given by
Maximum angular speed reached by the flywheel is 28.2743 rad/s
The ratio would be
