Well if your talking ABOUT the earth then they use satellite imagery and scan the earth, and I’m pretty sure they would know the bottom from the top because of the contents and such. But when i think about it there really isn’t a up and down on the earth cause it’s a sphere, or maybe the moon is the bottom and the sun is the top.

Calculate the peak voltage of a generator that rotates its 200-turn, 0.100 m diameter coil at 3600 rpm in a 0.800 T field.
m_a_m_a [10]

Answer:

The peak voltage is 473.86 V

Explanation:

Given;

number of turns of generator, N = 200  turn

diameter of the coil, d = 0.1 m

radius of the coil, r = 0.05 m

Magnitude of the magnetic field, B = 0.8 T

angular frequency, ω = 3600 rpm

angular frequency, ω (rad/s) = \frac{2\pi}{60} *3600\ rpm = 377.04 \ rad/s

The peak voltage is given by;

E = NBAω

Where;

A is the area of the coil = πr² =  π (0.05)² = 7.855 x 10⁻³ m²

E = (200)(0.8)(7.855 x 10⁻³)(377.04)

E = 473.86 V

Therefore, the peak voltage is 473.86 V

The current flow occurs due to the difference in _______.
Mice21 [21]

Answer:

The current flow occurs due to the difference in electrical potential

Explanation:

The difference in electrical potential between two point in electrical circuit causes charges to flow, usually from the region of higher potential to the region of lower potential. The flow of these charges is known as current.

Thus, the current flow occurs due to the difference in electrical potential. Electric potential means work done in moving a unit positive charge from infinity to a particular point in the field against the electrical resistance of that field.

Grape juice solid-conduction , solid-convection,fluid-conduction , fluid-convection
Gelneren [198K]

The process by which the heat energy is transmitted between the atoms or molecules is known as conduction.

Explanation:

Conduction is the transfer of heat through the material that are caused by temperature gradient with the material ends in heat flux. The heat transfer done by movement and mixing of a fluid is known as convection.

If a fluid is taken and it is kept as stationary. If there is a temperature gradient across that fluid, there would be transfer of heat that occurs in the fluid. It is negligible when compared to convective heat transfer.

Because of the heat transfer from solid to solid, density of liquid changes and start to move in upward direction due to low density. This type of motion is known as convection currents.

During exercise, the supply of oxygen and __________ to muscles increases. What one word completes the sentence?
kondaur [170]

Answer:

Glucose

Explanation:

During exercise, muscles need more energy. They get this energy by aerobic respiration, which uses oxygen and glucose to release energy.

Note: If the body fails to supply oxygen to the muscles fast enough, the muscles will produce energy by anaerobic respiration, which is not as effective as aerobic respiration in addition to producing lactic acid.
