I think it is c I'm only in 7th grade but I'm pretty sure that the answer is c
S^2=3^2+4^2
S^2=9+16
S^2=25
S=√25
S=5m
Answer:
1 m/s
Explanation:
Po = Pf
(0.050kg)(9 m/s) + (0.030kg)(v2) = (0.05kg + 0.030)(6 m/s)
0.45 kgm/s + (0.030kg)(v2) = 0.48 kgm/s
(0.030kg)(v2) = 0.03 kgm/s
v2 = 1 m/s
The frequency of a wave is the number of wave cycles per second. this quantity is given the symbol ν and has units of s^–1 or hertz.
What is a wave ?
A wave is a dynamic disturbance of one or more quantities that propagates through time. When waves oscillate frequently around an equilibrium value at a certain frequency, they are said to be periodic.
What is a wave cycle ?
The wavelength is the measured distance in meters between two waves' peaks or troughs, which is referred to as a wave cycle. It's crucial to remember that the distance from peak to peak equals the distance from trough to trough. The length of time it takes a wave to complete one cycle is known as the wave's period.
