Explanation:
It is given that,
Speed of a wave, v = 251 m/s
Wavelength of the wave, λ = 5.1 cm = 0.051 m
(1) The frequency of the wave is given by :
(2) Angular frequency of the wave is given by :
(3) The period of oscillation is given by T as :
T = 0.000203 seconds
or
T = 0.203 milliseconds
Hence, this is the required solution.
Answer:
Art
Explanation:
Polly's line is linear, while arts line is going up with constant velocity. There for art is going faster.
Answer:
The escape speed of the planet is 41.29 m/s.
Explanation:
Given that,
Speed = 52.9 m/s
Final speed = 32.3 m/s
We need to calculate the launched with excess kinetic energy
Using formula of kinetic energy
We need to calculate the escape speed of the planet
Using formula of kinetic energy
Hence, The escape speed of the planet is 41.29 m/s.
Answer:
wavelength.
Explanation:
One complete expression of a waveform beginning at a certain point, progressing through the zero line to the wave’s highest (crest) and lowest (trough) points, and returning to the same value as the starting point is called a is called wavelength. Its can be also defined as the distance between two successive crests or trough points in wave form.
