Which statement best describes the superposition principle?A. If two in-phase waves arrive simultaneously at a point, their amplitudes add up.
B. If two out-of-phase waves arrive simultaneously at a point, their amplitudes add up.
C. If two in-phase waves arrive at a point one after another, their amplitudes add up.
D. If two out-of-phase waves arrive at a point one after the other, their amplitudes adds up

Answers

Answer 1

Answer: C. If two in-phase waves arrive at a point one after another, their amplitudes add up.

Answer 2

Answer:

Final answer:

The superposition principle states that when two in-phase waves arrive simultaneously at a point, their amplitudes add up.

Explanation:

The correct statement that describes the superposition principle is option A: If two in-phase waves arrive simultaneously at a point, their amplitudes add up. In-phase waves have the same frequency, wavelength, and direction. When two in-phase waves meet, the amplitude of the resultant wave is the sum of the individual amplitudes.

Imagine that you are sitting in a closed room (no windows, no doors) when, magically, it is lifted from Earth and sent accelerating through space with an acceleration of 1g (9.8 m/s2). According to Einstein's equivalence principle, which of the following is true?You won't feel any change and will have no way to know that you've left the earth.
You'll feel a force that will cause your head to repeatedly bang into the ceiling.
You'll know that you left the Earth because you'll be floating weightlessly in your room.
You'll know that you left the Earth because when you drop a ball it will fall sideways.

Answers

Answer:

You won't feel any change and will have no way to know that you've left the earth.

Explanation:

One of the formulations of the principle says that the properties of an inertial system under the effect of a gravitational field are the same as a non-inertial(accelerated) system. The inertial system under the effect of a gravitational field occurs when you are in the room on earth, and when the room is sent accelerating through space you have the non-inertial system. Both have the same properties, so it's impossible to tell the difference if you can't look outside.

Can you please explain me how to do integration in physics in a easy way?

Answers

The easiest way to explain it is roughly identical to the way that your teacher explained it in class. If there were any easier way ... like writing it here in a few paragraphs ... then that's what the teacher would have done. You would have been given the easy explanation on the first day of class, printed on one sheet of paper, and you would have had the rest of the year to practice it and get really good at it.
If the class spent a month teaching it, then that's about how long it takes. Sorry.
