Water flowing over the Albright Falls in Yellowstone National Park drops 79 m. If all of the water's energy goes to heat it, wha
Elodia [21]

Answer:

0.185 ^{\circ}C

Explanation:

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

E_g=E_i\\mgh=mC\Delta T

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

\Delta T is the change in temperature

In this problem, we have:

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

g=9.8 m/s^2 is the acceleration due to gravity

C=4186 J/kg^{\circ}C is the specific heat capacity of water

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

\Delta T=\frac{gh}{C}=\frac{(9.8)(79)}{4186}=0.185 ^{\circ}C

In interactions of action-reaction pairs involving Earth and everyday objects, the effect on Earth's motion is often negligible
Alekssandra [29.7K]

Answer:

...The earth has a great mass. Since mass and inertia are directly proportional to each other, the larger the mass of the object, the more inertia that it has. Inertia is the objects resistance to a change in motion.

The two populations of stars in our galaxy are actually quite similar in many of their characteristics. True False
stich3 [128]

Answer:

False

Explanation:

The two population of stars in our galaxy are nowhere near similar in many characteristics.

For instance, the stars in the milky way galaxy are about 2/3 of all observable stars. Yes, the populations of stars in the milky way and outside of it are both large, but the population in the milky way galaxy is double that of elsewhere.
