A frequency spectrum shows a tone that is composed of a frequency of 440 h z, 880 h z, and 1320 h z. the 880 h z and 1320 h z frequencies are called. sine wave.
Frequency, in physics, the wide variety of waves that skip a hard and fast point in unit time; also, the variety of cycles or vibrations gone through for the duration of one unit of time via a body in periodic movement.
The variety of durations or often happening occasions of any given type in unit of time, typically in one 2nd. the variety of cycles or finished alternations in keeping with unit time of a wave or oscillation. symbol: F; Abbreviation: freq.
Frequency is an crucial parameter used in technological know-how and engineering to specify the temporal charge of change located in oscillatory and periodic phenomena, along with mechanical vibrations, audio indicators, radio waves, and mild.

Answer:
Amplitude, A = 0.049 meters
Explanation:
Given that,
A harmonic wave travels in the positive x direction at 6 m/s along a taught string. A fixed point on the string oscillates as a function of time according to the equation :
.......(1)
The general equation of a wave is given by :
.......(2)
A is amplitude of wave
On comparing equation (1) and (2) we get :
A = 0.049 meters
So, the amplitude of the wave is 0.049 meters.
Answer:
No, projectile launched at 20° landed first.
Explanation:
70° projectile had a vertical velocity of v*sin(70), which is significantly bigger than v*sin(20). Since v=vx+at, we can see that
solve for t, you can check that by substituting velocity for any number.
Answer:
91.64 km
91.64 km high material would go on earth if it were ejected with the same speed as on Io.
Explanation:
According to Newton Law of gravitation:
Where:
G is gravitational constant=
For Moon lo g is:
According to law of conservation of energy
Initial Energy=Final Energy
For Jupiter's moon Io:
Velocity is given by:
For Earth Velocity is given by:
Now:
91.64 km high material would go on earth if it were ejected with the same speed as on Io.
