The period of a water wave with a frequency of 0.5 Hz is 2 seconds. Frequency is the inverse of the period (t) and it is the number of oscillations per unit time or is the number of repetitions of an event by an object per unit time. Frequency can also be calculated in terms of wavelength and speed of light.
D) The members are the same species
Answer:
The height of the ball after 5 seconds is 162 ft.
Explanation:
First, replace the variable <em>t</em><em> </em>with how many seconds the ball has dropped, which in this case is 5.

Solve.

For a duration of 5 seconds, the ball had managed to drop 350 feet, with 162 feet left to go to touch ground level.
Answer:
Average velocity of the bird is 2.54 m/s.
Explanation:
Given that,
Initial speed of the bird, u = 0
It experiences a displacement of, d = 28 m
Time taken, t = 11 s
We need to find the average velocity of the bird. Let v is the average velocity. Mathematically, it is given by :


v = 2.54 m/s
So, the average velocity of the bird is 2.54 m/s. Hence, this is the required solution.
They become charged particles called ions.
