Answer:
f = 130 Khz
Explanation:
In a circuit driven by a sinusoidal voltage source, there exists a fixed relationship between the amplitudes of the current and the voltage through any circuit element, at any time.
For an inductor, this relationship can be expressed as follows:
VL = IL * XL (1) , which is a generalized form of Ohm's Law.
XL is called the inductive reactance, and is defined as follows:
XL = ω*L = 2*π*f*L, where f is the frequency of the sinusoidal source (in Hz) and L is the value of the inductance, in H.
Replacing in (1), by the values given of VL, IL, and L, we can solve for f, as follows:
f = VL / 2*π*IL*L = 12 V / 2*π*(3.00*10⁻³) A* (4.9*10⁻³) H = 130 Khz
Answer:
For 1 week total cost will be equal to 0.2912
Explanation:
We have given power P = 40 watt
Light is on from 6 pm to 7 am
So total time = 13 hours
We know that energy is given by

So energy will be 
We have given cost per KWh is 0.08
So total cost per day will be = 0.08 ×0.520 = 0.0416
For 1 week that is for 7 day total cost will be = 7×0.0416 = 0.2912
The ability to convert voltage to and from mechanical stress.

Explanation:
<u>Properties of a virtual image:</u>
1. Image formed cannot be projected or focused on a screen.
2. The distance of the object to the mirror is the same as the distance from the image to the mirror.
3. The size of the image formed is the same as the size of the object.
4. The image formed is laterally inverted. That is the right becomes left and vice versa.
5. The image is upright.
<u>Properties of a real image:</u>
1. Image formed can be projected on a screen.
2, The distance from the image to the mirror is not the same as the distance from the object to the mirror.
3. The size of the image is not the same as the size of the object.
4. Image formed is upside down.
