The answer is, C. the wavelength is measured in parallel to the direction of the wave, at any point, under the same repetition for any type of wave.
Here we will say that there is no external torque on the system so we will have

here we know that

where we know that

Also we know that

initial angular speed will be

now from above equation



now we have

so final speed will be 2.41 rad/s
Answer:

Explanation:
The rectangular components of a vector
having a magnitude v and angle θ are:


The golf ball has an initial speed of 75 m/s at an angle of 60 degrees.
The variables of the equations have the values:
v = 75 m/s
θ = 60°
Substituting into the formula:



Without specifying units and with precision to the hundredths place:

1. D:Asteroids have geological activity
2.A:Short-period comets circle around the sun in 200 years or less and originate in the Kuiper Belt
3.D:All of the above
4.A:It’s gravity is too weak to clear it’s orbit
5.B:Ceres
6.C:Haumea
7.A:Is bigger than Pluto
I hope this helps
