A converging lens can produce both real and virtual images depending on the position of the object. Explain when converging lenses can produce virtual images and describe the image produced.A) A virtual image is produced if the object is on the focal point, the image is upright, enlarged and on the same side of the lens as the object.

B) A virtual image is produced if the object is on the focal point, the image is inverted, enlarged and on the opposite side of the lens from the object.

C) A virtual image is produced if the object is between the focal point and the lens, the image will be upright, enlarged and on the same side of the lens
as the object.

D) A virtual image is produced if the object is between the focal point and the
lens, the image will be upright, reduced and on the opposite side of the
lens from the object.

Answer:

Where is this image?

When you lift a box up off the floor, you must exert a force at least equal to the weight of the box. If you lift the box at constant speed, you "do work" on the box that would be equal to the force you exert (the weight of the box) times the height through which you lifted the box. If you exert a force of 50 Newtons on the box and lift it 1 meter high, then you did (50 N)x(1 m) or 50 N-m of work on the object. 1 Newton-meter is called a Joule (J), pronounced "jewel." In lifting the 50 N box upward 1 meter at constant speed, you would do 50 Joules of work on the box. That means your body used 50 J of energy to lift the box.

and here is the Equation for Work: Work = Force x distance, or W = F d.

Answer: C) Unscrew one light. If the other lights turn off, it's a series circuit.

Explanation:

In a series circuit, all the components in the same path. The current in the entire circuit is same. The voltage drop across each component is different. If one component does not work, the entire circuit breaks and other components also stop working. On the other hand, in a parallel circuit, voltage drop across all the components is equal. Trouble in one component does not effect other components.

Hence, to check whether the lights are connected in series or in parallel, one light should be unplugged and if the other lights still work, it means they are connected in parallel otherwise in series. Thus, correct option is C) Unscrew one light. If the other lights turn off, it's a series circuit.
