Answer:

the answers the correct one is d

Explanation:

The speed of sound is constant so we can use the relations of uniform motion

           v = x / t

            x = v t

now let's calculate the distance for each person

t = 5s

         x₁ = 300 5

         x₁ = 1500 m

t = 6s

         x₂ = 300 6

         x₂ = 1800 m

therefore we have two possibilities

a) the two people are on the same side, therefore the distance between them is

         Δx = x₂- x₁

         Δx = 1800 - 1500

         Δx = 300 m

       

let's reduce to km

         Δx = 0.300 km

b) people are on opposite sides of the sound

         Δx = x₂ + x₁

         Δx = 1800 + 1500

         Δx = 3300 m

         Δx = 3.3 km

when checking the answers the correct one is d

Answer:

A. nuclear fusion reactions

C. it's still hot from the big bang

Explanation:

The inside of the earth is hot due to some reasons. This heat provides the internal energy the drives processes within the earth interior. Here are some of the ways in which the heat has accumulated:

  • Nuclear reactions within the earth interior by fusion and other radioactive processes releases a large amount of heat.
  • Some heat accreted during the early formation of the earth and has not been lost till this day.
  • Heating due to friction

These are some of the sources of the earth's internal heat.

Which of the following is an example of an even population distribution?
icang [17]
Even population distribution refers to a type of population distribution in which the arrangement is done in such a way that the distance between neighboring individual is maximized and uniform. This type of population distribution is usually found on the farm land, where the space in which the crops are planted have been carefully measured out. Thus an example of even population distribution is corn planted in a field.
