The frequency of any wave is (speed) / (wavelength).
Frequency = (330 m/s) / (2m) = 165 per second = <em>165 Hz</em>.
Period = 1 / frequency = 1 / (165 per second) = <em>0.0061 second </em>
Answer:
Self-pollination occurs when pollen from one plant lands on the pistil of a flower on the same plant. Cross-pollination occurs when pollen from one plant reaches the pistil of a flower on a different plant.

Answer:
Angular acceleration,
Explanation:
Given that,
Initial angular velocity,
The final angular velocity,
Time, t = 4.2 s
We need to find her average angular acceleration during this time interval. Acceleration is the rate of change of velocity. So,
So, her average angular acceleration is .
