Consider a traveling wave described by the formula
Harrizon [31]

Answer:

The wave is traveling in the +x direction.

Explanation:

The equation of a wave is given by the formula as :

y(x,t)=A\ sin(kx-\omega t)

Here,

A is the amplitude of wave

(kx-\omega t) is the phase of wave

\omega is the angular frequency of the wave

We need to find the correct statement out of given options. The given equation can be rewritten as :

y(x,t)=A\ sin(\omega t-kx)

Here, the propagation constant is negative. So, the wave is moving in +x direction. Hence, the correct option is (a).

lana66690 [7]
The height difference is found by
\delta H=400sin(5 \°)=34.86m
Then the change in potential energy is
E=mgh=(80.0kg)(9.8 \frac{kgm}{s^2})(34.86)= 27332J
