What is the period of a wave if the wavelength is 10 m and the speed is 200 m/s?

20 hertz

Step-by-step explanation:

Given:

      Speed of the wave =200 m/s

      wavelength of the wave = 10 m

According to the formula :

Frequency=speed/wavelength

Frequency= 200/10

20 hertz or 20 wave periods per second

So, the number of periods of wave passing per second is 20

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)
