Test populations are studied. Population one is found to obey the differential equation dy1/da=o.2y1 and the population two obey

oksano4ka [1.4K]

Answer:

Population 1 indicates growth while Population 2 indicates a declining population

Explanation:

Here, using the given rate of change of the population, we want to determine which of the two is growing and which is declining

From the rate of change of both, we can determine this. Looking at the differential equation for the first one, we can see that it is of positive value. Looking at the differential equation for the second one. we can see it is of negative value

While a positive change rate indicates growth, a negative change rate will indicate otherwise

Hence, we can conclude that the one with a negative rate change will indicate a declining population

How would the gravitational force between the earth and the moon change if the moon had half the mass?

Vikki [24]

The moon's gravity, combined with the waltz of Earth and the moon around their center of mass, forces the oceans into an oval shape, with two simultaneous high tides. ... If the moon were half its mass, then the ocean tides would have been correspondingly smaller and imparted less energy to it.

According to Ohm's law, which is stated as I = V + R, which two sentences are true?

Novay_Z [31]

So, If the resistance decreases, then the current increases. Assume voltage is constant.

If the voltage increases, then the current increases. Assume resistance is constant.

Explanation:

According to the ohm's law; I = V/R;

If the resistance decreases the current increases assuming that the voltage is constant
if the voltage increases, then the current increases assuming that the resistance is constant.

Based on Ohm's law, we know that the current through a metallic conductor is directly proportional to the voltage across the ends.

From the relationship;

I = $\frac{V}{R}$

we see that V = IR

These equations affirms that

If the resistance decreases the current increases assuming that the voltage is constant based on the second equation

if the voltage increases, then the current increases assuming that the resistance is constant based on the first equation.
