A plane progressive

Physics
1 answer:
kiruha [24]3 years ago
4 0

Answer:

Amplitude, A = 5 m

Explanation:

Let a progressive wave is given by equation :

y=5\sin (100\pi t-0.4\pi x) .....(1)

The general equation of a progressive wave is given by :

y=A\sin (\omega t-kx) ....(2)

Here,

A is the amplitude of the wave

\omega is the angular frequency

k is propagation constant

We need to find the amplitude of the wave.

If we compare equations (1) and (2), we find that the amplitude of the given plane progressive wave is 5 m.

PIT_PIT [208]

Answer:

a) 17 km

b) 9 km

Explanation:

The distance is the length of the path.

A to C: 5 km

B to C: 4 km

C to B: 4 km

B to C: 4 km

Total distance = 5 km + 4 km + 4 km + 4 km = 17 km

Displacement is the difference between the starting point and ending point.

Displacement = 9 km − 0 km = 9 km
