Marc and Linh stretch out a long spring on the classroom floor. Marc holds one end of the spring still. Linh creates waves in the spring by moving the other end right and left with a frequency of 2 Hz. If wave crests are 0.5 m apart, what is the speed of the waves?

Answers

Answer 1

The speed of the wave created by Linh in the spring by moving the other end right and left with a frequency of 2 Hz is 1m/s.

How to calculate speed of a wave?

The speed of a wave can be calculated by using the following formula:

Speed = Wavelength x Frequency

According to this question, Linh creates waves in the spring by moving the other end right and left with a frequency of 2 Hz. If wave crests are 0.5 m apart, the speed can be calculated as follows:

speed = 2Hz × 0.5m

speed = 1m/s

Therefore, the speed of the wave created by Linh in the spring by moving the other end right and left with a frequency of 2 Hz is 1m/s.

The force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.

Force on the charge

The force on the charge is calculated as follows;

F = k(q1q2)/r²

where;

r is the distance between the charges = 2 m - 1m = 1m

F = (9 x 10⁹ x 10⁻⁹ x 2 x 10⁻⁹)/(1)²

F = 1.8 x 10⁻⁸ N

Thus, the force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.

Voltage is always twice the amount of power. This is statement is accurately describe the relationship between voltage and electric power.

What is Power?

Power is defined as amount of energy transferred or converted per unit time.

From power-current relation

P=VI

Also, From Ohm's Law we know that,

V= IR

Replacing the value of V in the above equation,

[tex]P =\frac{I^{2} }{R}[/tex]

When the values for current and resistance are given then the equation is,

Why is the contribution of the wavelets lying on the back of secondary wave front zero?​

Answers

Answer:

The contribution of the wavelets lying on the back of the wave front is zero because of something known as the Obliquity Factor. It is assumed that the amplitude of the secondary wavelets is not independent of the direction of propagation, Sources: byju's.com

According to the Voigt and Kirchhoff's law for wavelets, the contribution of a wavelet in any direction making an angle x with the normal to the wavelet is proportional to {1+cos(x)/2)}

For wavelet lying on the back of secondary wavefront,

x = 180°

→ So, the proportional factor:

→ {1+cos(180°)/2}

→ (1-1/2)

→ (0/2)

→ 0

That's why the contribution of the wavelets lying on the back of secondary wave front is zero
