Wave a has an amplitude of 3, and wave b has an amplitude of 3. what will happen when the trough of wave a meets the trough of wave b?

Explanation:

It is given that both wave have same amplitude i.e

Now, we need to find what will happen to the waves when trough of wave A meets the trough of wave B.

It means that both waves are in same phase i.e, the phase difference between them is 0 degree.

We know resultant amplitude of two waves of same amplitude A with phase difference is given by.

In this case , A=3 and

Putting value of A and in above equation.

We get,

Therefore, a new wave will form of resultant amplitude of 6.

Hence, it is the required solution.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
