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:
1.8 Kg 17.6N
Explanation:
I don't know the explanation hahaha
dry ice is one example of this.
Answer:
B. 312.5 J
Explanation:
Work = change in energy
W = ½ mv₂² − ½ mv₁²
W = ½ m (v₂² − v₁²)
W = ½ (5 kg) ((15 m/s)² − (10 m/s)²)
W = 312.5 J
