A biconvex lens with an object at 2 F. Rays are drawn both parallel to the principal axis and through the center of the lens. The ray parallel is bent through the focal point on the image side of the lens. The ray straight through the center of the lens is not bent. The rays converge at the image at 2 F on the image side of the lens that is inverted and the same size as the object. What are the characteristics of the image formed by the object?
ANSWER
The image created by the object is located on 2F behind the lens, real, inverted, and the same size as the actual object.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
