Explanation:
Because combining primary colors od light like red, blue, and green created secondary colors like yellow, cyan, and magenta
Answer:
b. 40V , 40V
Explanation:
Connections are as per the figure.
As total current through source is 4A , current through each lamp is 1A.
As total resistance of the circuit is 10Ω ,resistance of each bulb is 40Ω because in case of a parallel circuit in which identical objects are connected , 
where R is the resistance of each bulb and n is the number of bulbs.
As per Ohm's law , voltage of the source =IR = 4×10 =40V.
We can see from the figure that if the voltage across the source is 40V , the voltage across each bulb is also 40V.
Answer:
70.35%
Explanation:
The relative humidity is a percentage and is the ratio between the partial pressure of water and the vapor pressure of water times 100% The partial pressure gives you an idea of the amount of water in the air whereas the vapor pressure is related with the maximum amount of water that can be in the air for a given temperature.
Vp(h2o) -> Vapor pressure of water
p(h2o) -> Partial pressure of water
RH -> Relative humidity
Vp(h20) at 22°C = e^(20.386 - (5132 / (temperature + 273)) = 19.9 Torr
(1 Torr == 1 mm Hg)
RH = p(h2o)/Vp(h2o)*100% = (14/19.9)*100% = 70.35%
Note: The formula used to find the vapor pressure of water is an approximation, to get a better value you could use a table to determine the vapor pressure of water at a certain temperature. Remember that Vp(h2o) is a constant for a given temperature.
The correct answer is false.
