Would the energy of the wave increase or decrease if the speed of the wave increases? Why?
choli [55]

Answer:

i hope this helps some

Explanation:

The time-averaged power of a sinusoidal wave is proportional to the square of the amplitude of the wave and the square of the angular frequency of the wave. This is true for most mechanical waves. If either the angular frequency or the amplitude of the wave were doubled, the power would increase by a factor of four.

The speed of a wave is dependant on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency (speed = l * f).

A proton of mass m is at rest when it is suddenly struck head-on by an alpha particle (which consistsof 2 protons and 2 neutrons
antiseptic1488 [7]

Answer:

3/5 v

Explanation:

The computation of speed will the alpha particle have after the collision is shown below:-

In a perfectly elastic the kinetic energy and collision the momentum are considered.

The velocity of the particles defines the below equation:

VA_f=(\frac{m_A-m_B}{m_A+m_B})VA_i+(\frac{2m_B}{m_A+m_B})VB_i

As we know that

VA_i=v

\\VB_i=0

Here, we consider A is the alpha particle and B is the proton and now by the above values we can solve the equation which is below:-

VA_f=(\frac{4m-m}{4m+m})v

\\VA_f=\frac{3m}{5m}v

\\VA_f=\frac{3}{5}v

Therefore the correct answer is \frac{3}{5}v

Use the worked example above to help you solve this problem. A wire carries a current of 21.8 A from west to east. Assume that a
PSYCHO15rus [73]

Answer:

Themagnitude of the force is 0.0415N and is directed vertically upwards. The solution to this problem uses the relationship between the Force experienced by a conductor in a magnetic field, the current flowing through the conductor, the length of the conductor and the magnitude of the electric field vector.

Mathematically this can be expressed as

F = I × L ×B

Where F = Force in newtons N

I = current in ampres A

L = length of the conductor in meters (m)

B = magnetic field vector in T

Explanation:

The calculation can be found in the attachment below.

Thedirection of the force can be found by the application of the Fleming's right hand rule. Which states that hold out the right hand with the index finger pointing in the direction of the magnetic field and the thumb pointing in the direction of the current in the conductor, then the direction which the middle finger points is the direction of the force exerted on the conductor. By applying this the direction is vertically upwards.
