what is the period of a wave if the wavelength is 100m and the speed of 200m/s
a. 100s
b. 200,000s
c. 0.5s
d. 2s

C

Step-by-step explanation:

The formula we use to solve this would be:  

Where

T is the period in seconds

is the wavelength in m, and

v is the speed of the wave in m/s

We have equal to 100, and v = 200 m/s. Plugging these into the equation, we get the period:

C is the right answer.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
