Answer:
378 Hz
Explanation:
When source of sound moves away from stationary listener
f' = f x V / ( V + Vs)
f' = 600 x 340 / ( 340 + 200)
f' = 204000/540
f' = 378 Hz
C. Sonography
Sonography makes use of sound waves.
Answer:
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil. The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.
Electromagnets
When an electric current flows in a wire, it creates a magnetic field around the wire. This effect can be used to make an electromagnet. A simple electromagnet comprises a length of wire turned into a coil and connected to a battery or power supply.
The data set that is most likely from the car equipped with ABS is :
<u><em>Although the plots related to your question is missing attached below is the missing data. </em></u>
The First plot ( acceleration vs time ) plot is the data that represents the application of brakes in a car fitted with ABS ( antilock braking system ) because of the absence of skidding effect between 6.5 and 9 seconds in the graph.
The skidding effect is present in the second plot around the same time because the car is not fitted with ABS
Hence we can conclude that the graph that shows the car fitted with ABS is the first plot .

The answer is electron
Explanation: An atom consists of a small but massive nucleus that include protons (positive charge) and neutrons (neutral charge). around the nucleus is a cloud of rapidly moving electrons (negative charge)
