What is the frequency of a wave if the wavelength is 100 m and the speed is 200 m/s?

a. 2 hz
b. 100vhz
c. 0.5 hz
d. 200,000 hz

The frequency is 2Hz

Using the formula

Arranging the equation

Frequency = Speed / Wavelength

Frequency = 200 / 100

Frequency = 2 Hz

2Hz

Step-by-step explanation:

i took the test

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
