The correct answer is the third one: move toward the ground state. Remember please that Elements produce their spectrum when their electrons move toward the ground state. Hope this is very useful
A sound wave is a longitudinal wave caused by vibrations and carried through a substance. The particles of the substance, such as air particles, vibrate back and forth along the path that the sound waves travel. Sound is transmitted through the vibrations and collisions of the particles.
This could maybe help you with your answer.
Asteroids do this because of Newton's Third Law. When a asteroid hits something, it will keep on moving (spinning) until it hits something else.
Answer:
Explanation:
Total resistance of 2 bulb in series
= 100 +100 = 200 ohm
current in each bulb
= 9/200 = .045 A
In case of parallel combination of bulb
total resistance
= 100 x 100 / (100+100)
50 ohm
current in the main circuit
= 9 / 50 A
current in each bulb
= 9 / (2 x 50)
.09
So in the second case current is more , hence heat generated too will be more . So brightness too will be more.
First set ( in series ) will be dimmer.
