Assume that 10 waves pass a fixed point in 5 seconds. what's the frequency of the wave in hertz?

2 hertzs

Explanation:

Frequency is defined as the number of cycle of waves that occur in one second.

Here the total number of cycle is equal to 10

The total time in which these 10 cycles occur is equal to 5 seconds

Now, mathematically frequency is equal to

where is equal to number of cycles

and t is time

Putting the given values in above equation we get -

hertzs

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
