Answer:
39 m/s
Explanation:
speed = frequency x wavelength (All SI Unit)
speed = 100 Hz x 0.30 m = 30 m/s
V = I • R
V = (0.054 A) • (152 ohms)
V = 8.208 volts
None of the listed choices is correct.
F=550N
1100×0.5=550N
the higher the value of the coefficient of friction the MORE the resistance to sliding .
