Answer:
B
Explanation:
If you pass white light through a blue filter, then only blue color will appear on the other end. This is because a blue filter will only allow blue light through it. And will absorb other color. In other words the rest colors would disappear. Hence the camera would receive just blue light. This phenomenon is referred to as color by subtraction.
Answer:
Flux is 21 Nm^2/C.
Explanation:
Electric field, E = 6 N/C along X axis
Electric filed vector, E = 6 i N/C
Area, A = 4 square meter
Area vector

The flux is given by

Answer:
0.94 m³/s
Explanation:
From the question given above, the following data were obtained:
Air flow (in ft³/min) = 2×10³ ft³/min
Air flow (in m³/s) =.?
Next, we shall convert 2×10³ ft³/min to m³/min. This can be obtained as follow:
35.315 ft³/min = 1 m³/min
Therefore,
2×10³ ft³/min = 2×10³ ft³/min × 1 m³/min / 35.315 ft³/min
2×10³ ft³/min = 56.63 m³/min
Finally, we shall convert 56.63 m³/min to m³/s. This can be obtained as follow:
1 m³/min = 1/60 m³/s
Therefore,
56.63 m³/min = 56.63 m³/min × 1/60 m³/s ÷ 1 m³/min
56.63 m³/min = 0.94 m³/s
Thus, 2×10³ ft³/minis equivalent to 0.94 m³/s.
Answer:
Hi,
The correct answer option is; D. Most of the current will flow through one part of the circuit.
Explanation:
A short circuit is a low resistance path in an electric connection between two conductors supplying current in a circuit.
It happens when excess amounts of current flow in the power source through a 'short path'.
Short circuits occur at very high temperatures which is of course caused by the heat produced during dissipation.
An example of application of short circuit is arc welding, where heating is achieved through short circuit.
