The correct answer is Emigration.

Emigration is the phenomenon in which a certain amount of population migrates from a place to another place.

This leads to decrease in population as, people are moving out from a place and death rate is also high.

Reason of emigration can be social pressure, lack of resources, lack of stability, et cetera.

Gold has a specific heat of 0.129 J/(g×°C). How many joules of heat energy are required to raise the temperature of 15 grams of

Elodia [21]

Answer:

$\boxed {\boxed {\sf 121.905 \ J }}$

Explanation:

We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

$q= mc \Delta T$

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.

ΔT= final temperature - initial temperature
ΔT= 85 °C- 22°C = 63°C

Now we know all the values:

$m= 15 \ g \ \\c= 0.129 \ J / (g* \textdegree C) \\\Delta T= 63 \ \textdegree C$

Substitue the values into the formula.

$q= (15 \ g)( 0.129 \ J / (g* \textdegree C)) ( 63 \ \textdegree C)$

Multiply the first numbers together. The grams will cancel.

$q= (1.935 \ J/ \textdegree C) ( 63 \ \textdegree C)$

Multiply again, this time the degrees Celsius cancels.

$q= 121.905 \ J$

121.905 Joules are required.

Which of the following best describes the movement of energy in an ecosystem

balu736 [363]

Energy is started from the sun, with 100 percent of the energy given to plants. when the plants are eaten, only 10% of that energy is given to the animal, like a rabbit. When the rabbit is eaten by a larger predator, only 10% is given of the rabbits energy. This continues, so to find the amount of energy within a certain organism you would need to calculate 10% from each original source of energy
