Answer:
v = 60 m/s
Explanation:
It is given that,
A wave is represented by the equation :
![y=0.2\sin [0.4\pi (x-60)t]](https://tex.z-dn.net/?f=y%3D0.2%5Csin%20%5B0.4%5Cpi%20%28x-60%29t%5D)
We need to find the velocity of the wave
The general equation of a wave is given by :
....(1)
Equation (1) can be written as :
...(2)
If we compare equation (1) and (2) we get :
The velocity of a wave is given by :
So, the velocity of the wave is 60 m/s.
Answer:
The golf ball has a constant velocity
Explanation:
The energy of a photon is proportional to the speed of light and inversely proportional to the wavelength. The constant of proportionality is Planck's constant, <span>6.626 * 10^-34 Js</span>
E = hc/ {wavelength}
E = [ 6.626 * 10^-34 Js * 2.997 * 10^8 m/s ] / 0.124 m
E = 1.60 * 10^-24 J
