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

normal

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.

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

3
3 ohms

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.

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.

Light wave is composed of two components an electrical component and a component

magnetic
