Awave traveling in a string can be described by the function y of xt is equal to 3 times cosine of ( 0.5 times x - 4 times t ) where x is measured in meters, y is measured in centimeters, and t is measured in seconds. what is the speed of this wave?

8 m/s

Explanation:

y = 3 Cos (0.5 x - 4 t)

Compare with the standard equation of a wave

Here, T be the time period, λ be the wavelength and A be the amplitude of the wave.

Let the wave velocity is v.

By comparison

2 π / T = 4

T = 2 π / 4 = π / 2 second = 0.5 π second

And

2 π / λ = 0.5

λ = 2 π / 0.5 = 4 π

use v = f λ = λ / T

v = 4 π / 0.5 π = 8 m/s

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.

answer; equivalent to a one(1) horsepower motor;
