Electromagnetic waves don't require a medium to travel.
14. The Aurora is an incredible light show caused by collisions between electrically charged particles released from the sun that enter the earth's atmosphere and collide with gases such as oxygen and nitrogen. The lights are seen around the magnetic poles of the northern and southern hemispheres.

About 5.4 billion years from now, the sun will have exhausted all of its hydrogen. The sun's core will get really hot and dense, thus shrinking; however, the outer region of the sun will expand and grow. ... Even if the expanding dying sun doesn't reach Earth, the sun's high temperatures will completely burn the planet.
They work on a weightless planet, therefore they have very little muscle control since they float in space !!
Answer:
120 mA
Explanation:
The relationship between voltage, current and resistance in a circuit is given by Ohm's law
where
I is the current
V is the voltage
R is the resistance
In this problem, we have an initial current of
I = 60 mA
Then the voltage is doubled:
V' = 2 V
while the resistance is kept the same:
R' = R
So the new current is
so, the current has doubled. Since I = 60 mA, the new current is
Temperature and pressure are directly proportional to each other. If this helps,please pick me the best. Also,please say thanks.
