On the galapagos islands, Darwin studied many creatures, including finches. Explain what he observed and how it relates to natur
Tatiana [17]
Darwin observed the beaks of the birds and how the different beaks helped the birds to eat different types of seeds.

This relates to natural selection because certain finches with say a smaller shorter beak would be able to eat only smaller seeds and fruits as to where a finch with a longer larger beak could eat larger bigger seeds and fruits. 

Hope this helped! Have a great day!

What is the gravitational potential energy associated whit the spoon at the height relative to the surface of the table.If a spo
igomit [66]

Answer:

0.062J

Explanation:

Given parameters:

Height of raising the spoon = 21cm

Mass of spoon  = 30g

Unknown:

Gravitational potential energy  = ?

Solution:

The gravitational potential energy of a body is the energy by virtue of the position of a such a body in space.

It is given as:

   G. P. E  = mgh

where m is the mass

          g is the acceleration due to gravity

          h is the height

Convert the parameters to appropriate units.

      21cm to m gives 0.21m

      30g to kg gives 0.03kg

   G.P.E  = 0.03 x 9.8 x 0.21  = 0.062J
