In a series circuit . . .
There is only one path for current to take.
All the way from one terminal of the power supply, through all of
the lights, computers, vending machines, air conditioners and
everything else in the building, to the other terminal of the electric
supply. One path !
So the current for EVERY device has to flow through ALL of them,
because that's the only path there is.
If any ONE device in the building was turned off, burned out, or
unplugged from the outlet, then there would be NO PATH for the
current, and everything in the building would lose power !
Not a very convenient way to operate a house or a building.
The answer is A rivers, lakes, and streams don't contain salt.
The runner's total distance covered was 800 meters. Her displacement (straight-line distance between start-point and end-point) was zero.
Her average speed = (distance)/(time) = 4.04 m/s
Her average <em>velocity</em> = (displacement) / (time) = <em>zero (choice - c)</em>
Answer:
The angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°
Explanation:
Given:
Refractive index for red light 
Refractive index for violet 
Refractive index for air 
Incident angle
28.30°
According to the snell's law,

For red light,

Where
transmitted angle for red light
50.18°
For violet light,

Where
transmitted angle for violet light
51.9°
Angular separation between red and violet light is given by,
1.72°
Therefore, the angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°
