b) The wavelength doubles
c) The speed of the wave doubles
d) The wavelength is cut in half
e) The speed of the wave is cut in half
Doubling the frequency of a transverse wave on a string would result in the wavelength of the wave being halved. This is due to the inverse relationship between frequency and wavelength in the context of wave speed remaining constant.
When considering a transverse wave travelling on a string, if the frequency is suddenly doubled, then the wavelength would be cut in half rather than any other given option. This is because the speed of a wave is determined by the medium through which it travels—in this case, the string—rather than its frequency or amplitude. Because the speed remains constant when the frequency doubles, the only factor left to adjust is the wavelength, according to the wave speed equation 'v = fλ', where 'v' is wave speed, 'f' is frequency, and 'λ' is wavelength. Thus, frequency and wavelength have an inverse relationship: if frequency increases (doubles, in this case), wavelength must decrease (halve) to maintain the constant wave speed.

Answer:
-3044.848m/s^2
Explanation:
Initial velocity = 15.7 m/s (u)
Final velocity = -14.444 m/s (v) velocity after striking moving opposite direction.
Time = 0.0099 s
Average acceleration :
change in velocity/ total time
= V - U/t
= -14.444 m/s - 15.7 m/s/0.0099 s
= -30.144/0.0099 s
= -3044.848m/s^2
