Question

WILL GIVE BRAINLIEST

Answer 1

Answer:

C

Step-by-step explanation:

The formula we use to solve this would be:  $T=\frac{\lambda}{v}$

Where

T is the period in seconds

$\lambda$ is the wavelength in m, and

v is the speed of the wave in m/s

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

$T=\frac{\lambda}{v}\\T=\frac{100}{200}\\T=0.5$

C is the right answer.

Answer 2

Answer:

C. O.5s

Step-by-step explanation:

If the wave length is 100m and it goes at a speed of 200m/s then it will only take 0.5 seconds because 100 is half of the speed of 200
