Frequency of 2 hertz and wavelength of 5 meters. Calculate speed.

Speed = 10 m

Explanation:

Given

wavelength = 5 m

frequency = 2 Hz = 2

Speed = ?

We know that for all waves, the relationship between wavelength λ, frequency f and speed v is same and given by the equation:

                                v = fλ

Hence, Speed = 2 x 5 m

                         = 10 m

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
