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
Waves with a frequency of 2.0 hertz are generated along a string The waves have a wavelength of 0.50 meters The speed of the waves along the string is
v=f*wavelength v=2*.5 v=1 m/s
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.
A string of 15 Christmas tree lights is connected in series to a 90 volt power source What is the value of the resistance of each light if the current flowing through the circuit is 2 amps
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect
50 degrees Fahrenheit is what in Celsius
50 degrees Fahrenheit = 10 degrees Celsius.
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
In a wave which of these is the number of vibrations per second
The number of vibrations per second is the frequency.
A pulley system is used to lift a 2000 newton engine up a distance of 3 meters The operator must apply a force of 250 newtons to the chain of the pulley system to lift the motor To lift the engine fi
The speed of sound in water is 1430 meters per second Find the wavelength of a sound with a frequency of 286 Hz traveling through the water
