When you turn on a battery-operated device, an electrical circuit is closed.
Explanation:
A circuit works, only when it is closed. When we turn on the battery-operated device, the circuit is closed & complete. Hence, the current will flow across the circuit.
Only closed circuits work (current flows through them). No current can flow in an open circuit.

We make a graphic of this problem to define the angle.
The angle we can calculate through triangle relation, that is,
With this function we should only calculate the derivate in function of c
That is the rate of change of .
b) At this point we need only make a substitution of 0 for c in the equation previously found.
Hence we have finally the rate of change when c=0.
Answer: The correct answer is option(d).
Explanation:
The light given by the combination of the all the seven colors is white color.
Generally white light splits into the band of seven colors when passed through the prism which is known as spectrum.
When the Anna shines a beam of light that includes all the wavelengths of visible light onto the wall she will observe the white light on the wall of the darken room.
Hence, the correct option is (d).
