Water flowing over the Albright Falls in Yellowstone National Park drops 79 m. If all of the water's energy goes to heat it, what is its temperature increase

Explanation:

When the water falls down, its initial gravitational potential energy is converted into internal energy. Therefore, we can write:

where

m is the mass of the water

g is the acceleration of gravity

h is the height of the water

C is the specific heat capacity of water

is the change in temperature

In this problem, we have:

h = 79 m is the change in height of the water

is the acceleration due to gravity

is the specific heat capacity of water

Re-arrnaging the equation, we can find the change in temperature:

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
