Displacement in Space
It is the length of a body's real route. It is the shortest distance between the body's final and beginning positions.
It's a number with a scalar value. It's a quantity with a vector.
It can't possibly be negative. It might be a negative number, a zero number, or a positive number.
That n2 = 2*n1. That is, the index of refraction is twice as big in medium 2 since v=c/n
Answer:
Explanation:
W = 75 watts
V = 110 volts
Formula
W = V * I
Solution
75 = 110 * I Divide by 110
75 / 110 = I
I = 0.6818 Amperes
Sunlight focuses at a point 18.5 cm behind the lens. As daylight comes from an indefinite distance, so it is a real image. The lenses that will focus on the parallel rays behind the lens are converging lenses.
What is a converging lens?
- A converging lens causes parallel rays of light to come to a focal point.
- A convex lens is a converging lens.
- A converging lens has a positive focal length.
- A converging lens forms a real or virtual image of a real object.
