this is a non graded disscussion i want to fill out it is just a worksheet to help me get better 30 points

1.) 30m/s

2) 5m/s

3) 40Hz

4) 400Hz

5) 300Hz

6) 0.77m

7) 0.386m

8) 0.625m

9) 100m/s

10) 50m/s

Explanation:

The speed of a wave (V) equals :

V = fλ ; where f = frequency, λ = wavelength

1.) f = 100Hz, λ = 0.30m

v = 100 * 0.30 = 30m/s

2) f = 50Hz λ = 0.10m

v = 50 × 0.10 = 5m/s

3) v = 20m/s, λ= 0.5m

f = v / λ

f = 20 / 0.5 = 40Hz

4) v = 80m/s, λ= 0.2m

f = 80/0.2 = 400Hz

5) v = 120m/s, λ = 0.4m

f = 120 / 0.4 = 300Hz

6) v = 340m/s, f = 440Hz

λ = v / f ; 340 / 440 = 0.77m

7) v = 340m/s, f = 880Hz

λ = 340 / 880 = 0.386m

8) v = 250m/s, f = 400

λ = 250 / 400 = 0.625m

9) f = 50Hz, λ = 2m

v = 50 × 2 = 100m/s

10) f = 100Hz, λ = 0.5m

v = 100 × 0.5 = 50m/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.
