The answer for the following question is answered below.
- <u><em>Therefore the speed of the wave is 0.60 m/s.</em></u>
- <u><em>The option for the following answer is " B".</em></u>
Explanation:
Frequency (f):
The number of the waves that pass a fixed place in a given amount of time is called frequency.
The SI unit of frequency is Hertz (Hz)
Speed (v):
The distance traveled per unit of time is called speed.
The SI unit of speed is m/s.
It is a scalar quantity.
Given:
wavelength of the wave (λ) = 0.10 m
frequency of the wave (f) = 60 Hz
To calculate:
speed of the wave (v)
We know;
According to the equation;
From the formula given below;
<u> v = f × λ</u>
Where;
v = speed of the wave
f = frequency of the wave
λ = wavelength of the wave
From the formula mentioned above;
v = 60 × 0.010
v = 0.60 m/s
<u><em>Therefore the speed of the wave is 0.60 m/s.</em></u>

Answer:
impulse applied to an object produces an equivalent vector change in its linear momentum, also in the resultant direction. The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram meter per second (kg⋅m/s).

Explanation:
All materials are superconducting at temperatures near absolute zero kelvin is false concerning superconductors.
Answer:
44.9 m
Explanation:
For ballistic motion in x-y coordinates, an appropriate equation can be ...
y(x) = -4.9(x·sec(α)/v)² +tan(α)x + h0
where α is the angle of launch from the horizontal, and v is the magnitude of the launch velocity.
Here, we have v = 15 m/s, and α = 0, so the equation reduces to ...
y = -4.9/225x^2 +44
For y = 0, we can find x to be ...
x^2 = (44×225/4.9) ≈ 2020.41
x ≈ 44.949
The stone hits the ground about 44.9 meters from the base of the cliff.
