Two waves travel in the same medium at the same speed. One has wavelength 0.0382 m and frequency 9.67×106 Hz. The other has wavelength 0.0486 m. What is the period of the second wave?
Speed(of first wave) = freq*wavelength (m/s)
Speed of the second wave is also the same. Since its wavelength is given, find the frequency. Reciprocal of the frequency is the time period in secs.
Amotorcycle slowed down to rest from avelocity of 10m\sec whiletraveling 30m what is its average acceleration
Motorcycle slowed down to rest from avelocity of 10 m\sec while traveling 30 m what
