(a) The frequency of water wave is 2 Hz.

(b) The wave speed of the water wave is 3.6 m/s.

<u>Explanation:</u>

(a) It is known that completion of one complete wave in 1 second is defined as frequency of 1 HZ. So here there are 120 waves crossing the boat in 1 minute. So the frequency of the water wave will be

$Frequency =\frac{\text { Number of waves }}{\text { Time in seconds }}$

As the time is 1 minute which is equal to 60 seconds and the number of waves is given as 120 then the frequency of the water wave is

$\text { Frequency }=\frac{120}{60}=2 \mathrm{Hz}$

So the frequency of water wave is 2 Hz.

(b) Then if the wavelength of the water wave is 1.8 m with a frequency of 2 Hz, then speed of the wave can be determined as the product of wavelength with frequency.

So Speed = Frequency × Wavelength

Speed = 2 × 1.8 = 3.6 m/s.

So the speed of the water wave is 3.6 m/s.

Explanation:

A circumpolar star is a star, as viewed from a given latitude on Earth, that never sets below the horizon due to its apparent proximity to one of the celestial poles.

What kind of situation could possibly have caused less energy to enter the Earth's system than exited it, several billions of ye

Sever21 [200]

Answer:

Methane, which generally produces more heat and energy got decreased in the Earth's system, leading to less energy in the Earth system and less energy absorbed by Earth's surface.

Explanation:

Methane produces a great deal of energy than any other gas that plays a role in the greenhouse effect. In several billions of years ago, humans were not engaging in activities that could increase the amount of methane in the earth's system most especially the atmosphere. Such activities that were not done include burning fossil fuel, raising livestock as we have now, and waste disposal. Natural process which includes natural air reduces some amount of methane in the atmosphere.
