Answer from: vontie

The correct answer is: Option (A) Electrically charged particles

Explanation:

A solar prominence, sometimes called filament, is a large, bright feature extending outward from the Sun's surface. On the other hand, solar flare is a sudden flash of increased Sun's brightness near its surface. Both of these phenomena are occurring because of the reactions of electrically charged particles at the surface of the Sun. Hence, the correct option is (A) Electrically charged particles.

Answer from: corban13

a. electrically charged particles

Explanation:

Surface of sun is made up of gases like hydrogen and helium

Now due to high temperature of sun the hydrogen gas nuclei has tendency to combine and give nuclear fusion reaction.

Due to this nuclear fusion of gas molecules it releases large amount of energy which will release large amount of accelerated charge particles. This large number of charge particles is known as Solar flare or Prominences.

These solar flares moves out at high kinetic energy and travels in all random directions

So here correct answer will be

a. electrically charged particles

Answer from: Quest

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm. the wire diameter is d = 0.9 mm. the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2) in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

answer: you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
