Answer:
B
Explanation:
Both low and high mass stars begin as nebulae, then become protostars. Both use nuclear fusion to form hydrogen in the main sequence.
The differences are that low mass stars have longer life cycles and become white dwarfs. High mass stars have shorter life cycles and undergo supernova explosions.

Answer:
Resulting amplitude, A = 0 cm
Explanation:
The phenomenon of interference occurs when two travel and meet at the same point. There are two conditions for interference. The first one is constructive and the other one is destructive.
In this case, two waves have same amplitude but they are not in same phase such that they meet at point X and destructive interference occurs.
Let A is the amplitude of the resulting wave such that,
A = 0
So, the amplitude of the resulting wave is 0 cm. Hence, the correct option is (A).
