A wave has a frequency of 250 hertz what is the period of the wave

One second


In which material does sound travel the fastest

Sound travels fastest through iron and sound travels slowest through air!

In this type of wave particles of the medium vibrate perpendicularly to the direction of the wave itself


A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor

It would be about 4 amps.

When measuring the angle of incidence and the angle of refraction the imaginary line drawn perpendicular to the surface at the point of incidence is called the


A ray of light strikes a flat surface of water The angle that the reflected light ray makes with the normal is called the angle of

The angle made is called the angle of incidence.

A soldier hears the sound of a distant cannon 6 seconds after he sees the flash How far away is the cannon

Using the speed of sound at 20° C, which is 343 m/sec, the cannon would be 2058 meters away. Temperature, pressure, and humidity could all affect the actual speed.

The speed of sound is approximately 340 ms If a sound wave has a wavelength of 0.68 meters the frequency will be approximately

No, the speed of sound may be 340 meters per second.

The frequency is speed of sound divided by wavelength.

So your frequency f = 340 / 0.68 = 500 Hz.

What is the frequency of a sound wave moving in air at room temperature if the wavelength is 0.686 meters

-===Answered by Cody p.===-

500 Hz.

Frequency of a wave increases

Wavelength of the wave decreases.

An ocean wave has a wavelength of 10 meters these waves pass by a stationary boat every 2.0 seconds the speed of the waves is


50 degrees Fahrenheit is what in Celsius

50 degrees Fahrenheit = 10 degrees Celsius.

A hiker walking through a canyon shouts Hello and hears an echo from the canyon wall 4 seconds later Approximately how far away is the wall

-===answered by Cody p.===-

686 meters

A string of 20 Christmas tree lights are connected in series to a 20 volt power source The bulbs each have a resistance of .5 ohm How much current is flowing through the circuit

2 amps. If it is D.C.

Five resistors are connected together in series One resistor is 2 ohms one is 3 ohms one is 4 ohms one is 5 ohms and the fifth is 6 ohms What is the total resistance

Purely additive. 2+3+4+5+6=20.

The loudness of a sound is a reflection of which of these


In a wave which of these is the number of vibrations per second

The number of vibrations per second is the frequency.

The echo of a ship's fog horn reflected from an iceberg is heard 8 seconds after the horn is sounded How far away is the iceberg

The iceberg is 1372 meters away.

Two planes are flying at the speed of sound Plane X is flying at an altitude of 6000 feet and plane Y is flying at an altitude of 15000 feet which is flying faster

Plane Y

What is the wavelength of middle C on a piano as it travels through air at standard temperature and pressure when The key of C is at 262 Hz Calculate your answer to the nearest tenth of a meter
