MArishka [77]

The frequency of the wave is 5 Hz and the amplitude is 0.002 m.

<h3>What is wave?</h3>

A wave is a disturbance in a medium that carries energy without a net movement of particles. In general, waves are classified into two types as Longitudinal and Transverse.

Given is a wave as shown in the image.

[A] -

The time period of wave [T] = 0.2 s

Frequency [v] = 1/T = 1/0.2 = 10/2 = 5 Hz

[B] -

Amplitude = maximum vertical displacement = 2mm = 0.002 m

Therefore, the frequency of the wave is 5 Hz and the amplitude is 0.002 m.

Effect of Heat on Matter Chemical Physical Change Change​
Oduvanchick [21]

Answer:

<h3>⭐Application of heat to certain substances causes only physical changes in which no new substance or substances are formed. Application of heat to some substances causes chemical changes, or chemical reactions, in which one or more new substances are formed, with different properties from the original.</h3>

A heater has a resistance of 10.0 Ω. It operates on a 12.0 V. What is the current through the resistor?
irakobra [83]

Answer:

1.2 amps :)

Explanation:

A heater has a resistance of 10.0 Ω. It operates on a 12.0 V. What is the current through the resistor?

         Known:

  • R = 10.0 Ω                            
  • V = 12.0 V

       Unknown:

  • I = ???

I = V/R

= 12.0 V / 10.0 Ω

= 1.2 amps

A student hears a police siren. What would change the frequency that the student hears? check all that apply
andriy [413]

Considering the Doppler efect, the frequency heard by the student would change if:

  • if the student walked toward the police car.
  • if the student walked away from the police car.
  • if the police car moved toward the student.
  • if the police car moved away from the student.

<h3>Doppler effect</h3>

The Doppler effect is defined as the change in the apparent frequency of a wave produced by the relative motion of the source with respect to its observer. In other words, this effect is the change in the perceived frequency of any wave motion when the sender and receiver, or observer, move relative to each other.

The following expression is considered the general case of the Doppler effect:

f'=f\frac{v+-vR}{v-+vE}

Where:

  • f', f: Frequency perceived by the receiver and frequency emitted by the transmitter, respectively. Its unit of measurement in the International System (S.I.) is the hertz (Hz), which is the inverse unit of the second (1 Hz = 1 s⁻¹)
  • v: Wave propagation speed in the medium. It is constant and depends on the characteristics of the medium. In this case, the speed of sound in air is considered to be 343 m/s.
  • vR, vE: Receiver and transmitter speed respectively. Its unit of measure in the S.I. is the m/s
  • ±, ∓:
  • We will use the + sign:
  1. In the numerator if the receiver approaches the sender
  2. In the denominator if the sender moves away from the receiver
  • We will use the - sign:
  1. In the numerator if the receiver moves away from the sender
  2. In the denominator if the sender approaches the receiver

In summary, the Doppler Effect is an alteration of the observed frequency of a sound due to the movement of the source or the observer, that is, they are changes in the frequency and wavelength of a wave due to the relative movement between the wave source and the observer.

<h3>Changes on the frequency </h3>

In this case, considering the Doppler effect, the frequency heard by the student would change if:

  • if the student walked toward the police car.
  • if the student walked away from the police car.
  • if the police car moved toward the student.
  • if the police car moved away from the student.
