What unit is used to measure resistance
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.
If there are four appliances connected to a single power source in series then the number of current paths is equal to
the answer is 1..
either 1 or 3 not sure. its deffinatly not 2 or 4
its deffinatly 1 XD
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
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
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.

50 degrees Fahrenheit is what in Celsius
50 degrees Fahrenheit = 10 degrees Celsius.
Which of these two regular polygons has the larger interior angle triangle or heptagon
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
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.
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
