The frequency of a wave is equal to the reciprocal of its period:
where f is the frequency and T the period.
The violin string of our problem emits a note with frequency f=440 Hz, so if we re-arrange the previous equation, we can find the period of the string's oscillation:
When the net forces equal 0 Newtons, they are a balanced force.
Answer:
age of rock is 2 million years
Explanation:
Where is mass remaining
is original mass
n= t/t(1/2) , which is the ratio of time to half life
= 1000atoms
=250 atoms
t =t(1/2) *n
t(1/2) =1000000 years
t=1000000 *2
t=2,000,000 years
It is Yellow, Cyan, Magenta . The answer is D.
This is a tricky one but on my part I'd have to say depending on the contract A,B,C.
