we know that
the speed is equal to
The slope of the line on the graph is equal to the speed of the car
so
during the segment B the slope of the line is equal to zero
that means
the speed of the car is zero
therefore
<u>the answer is the option B</u>
The car has come to a stop and has zero velocity
One with greater mass (8kg)
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.
