Red is the lowest because it has the shortest wavelengths
Answer:
D) 31 m, 19 Hz
Explanation:
The equation of the wave in the problem is
In general, the equation of a travelling wave is written as
where
A is the amplitude
is the wave number, with being the wavelength of the wave
is the angular frequency and f is the frequency
By comparing the two equations, we see that for this wave:
So now we can use the two equations for k and to find the wavelength and the frequency of the wave:
Answer:
Kinetic energy
Explanation:
Kinetic energy is the energy of motion, and the arrow is in motion.
Answer:
yes the acceleration changes..
Explanation:
as we know that that acceleration is a vector quantity, hence it changes with the change in either it's magnitude or direction and both and here in this condition the car changes it's direction from west to east hence it changes the direction so the acceleration changes too.
