Answer:
a.241.08 m/s b. 196 Hz c. 392 Hz
Explanation:
a. Determine the speed of waves within the wire.
The frequency of oscillation of the wave in the string, f = nv/2L where n = harmonic number, v = speed of wave in string, L = length of string = 1.23 m.
Since f = 588 Hz which is the 6 th harmonic, n = 6. So, making v subject of the formula, we have
v = 2Lf/n
substituting the values of the variables into v. we have
v = 2 × 1.23 m × 588Hz/6
v = 241.08 m/s
b. Determine the frequency at which the wire will vibrate with the first harmonic wave pattern.
The first harmonic is obtained from f when n = 1,
So, f = v/2L = 241.08 m/s ÷ 1.23m = 196 Hz
c. Determine the frequency at which the wire will vibrate with the second harmonic wave pattern.
The second harmonic f' = 2f = 2 × 196 Hz = 392 Hz
Answer:
5 Newtons Up and 5 Newtons Right
Explanation:
Treat each force vector as a value and choose the upward and rightward directions to be positive. Downward and Leftward forces will be considered "negative". For the vertical net force we have a positive 10 N upwards and a negative 5 N downwards. The net force in the vertical will be 5 N upwards. In the horizontal we have 10 N to the right and 5 N to the left. The net force in the horizontal will be 5 N to the Right.
It is easier if you split the motion into horizontal and vertical components.
