Answer:

72000 miles

Explanation:

If the distance between the students is 600 miles, and this implies in a 3 degree difference in the sun position, that means this 600 miles is related to 3 degrees of the circunference of the planet.

So, to find the whole circunference of the planet, that is, 360 degrees, we just need to use a rule of three:

3 degrees -> 600 miles

360 degrees -> x miles

3x = 600 * 360

x = 600 * 360 / 3 = 72000 miles

Hoochie [10]

Answer:

Energy stored at 12 volt will be 115.2 J and energy stored at 24 volt will be 460.8 volt

Explanation:

We have given capacitance of capacitor C = 1.6 F

Normal voltage V = 12 volt

And system uses 2 volt to charge the system

We know that energy stored in the capacitor is equal to E=\frac{1}{2}CV^2

So energy stored at 12 volt will be equal to E=\frac{1}{2}\times 1.6\times 12^2=115.2j

And energy stored at 24 volt will be equal to E=\frac{1}{2}\times 1.6\times 24^2=460.8j

So energy stored at 12 volt will be 115.2 j and energy stored at 24 volt will be 460.8 j

In Niels Bohr’s model of the atom, electrons move (1 point)like balls rolling down a hill.
DochEvi [55]
I think the correct answer from the choices listed above is the second option. In Niels Bohr’s model of the atom, electrons move like planets orbiting the sun. His model of atom is seen as<span> very small, positively charged nucleus which contains proton and neutron surrounded by negatively charged electrons.</span><span> These electrons travel in circular orbits around the nucleolus. </span>

Brad was hiring a new financial analyst, and he had several good candidates. He was leaning towards hiring Kai, a Japanese Ameri
Xelga [282]

Answer:

Brad is biased at falling into stereoryping. He believes Asians are good at math becuase there is a general idea about Asians being good at everything in regard to numbers, which may lead him to think kai is the best choice (which may be false).

Explanation:

Stereotypes

Stereotypes are ideas  believed by many people which explain characteristics about a group of people in a general way (social class, citizens of a specific place, etc) . In this case there is a stereotype about Asians being excellent and math and better than people from other continents. It is a way to generalize that is not true for every Asian in the world and may lead Brad to choose the wrong person for the position of finantial analyst due to this distortion in perception.
