Consider a traveling wave described by the formula

Physics
1 answer:
Harrizon [31]4 years ago
4 0

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).

What causes the pressure exerted by a gas in a container
yuradex [85]

The rapid motion and collisions of molecules with the walls of the container causes pressure (force on a unit area). Pressure is proportional to the number of molecular collisions and the force of the collisions in a particular area. The more collisions of gas molecules with the walls, the higher the pressure.

I hope this helps you.

A ball rolls 50 meters in
-Dominant- [34]

The speed of the ball is B. 5 meters per second

Explanation:

For an object in uniform motion (= at constant velocity), the speed can be calculated using the equation

v=\frac{d}{t}

where

v is the speed

d is the distance covered

t is the time taken

For the ball in this problem:

d = 50 m is the distance covered

t = 10 s is the time taken

Substituting, we find the speed:

v=\frac{50}{10}=5 m/s

Answer:

a = -1.6\ m/s^2

Explanation:

<u>Accelerated Motion</u>

It occurs when an object changes its speed over time. If the changes in speed are uniform, then the acceleration is constant, positive if the speed increases, negative if the speed decreases.

The acceleration is calculated as follows:

\displaystyle a=\frac{v_f-v_o}{t}

The aeroplane starts with a speed of vo=62 m/s and reaches a speed of vf=6 m/s in t=35 s.

The acceleration is:

\displaystyle a=\frac{6-62}{35}=-\frac{56}{35}

\mathbf{a = -1.6\ m/s^2}
