A concave lens can only form a virtual image. The correct option among all the options that are given in the question is the third option or option "C". Concave lenses are mostly thinner in the middle compared to its edges. I hope that this answer has come to your help.
The reason a tennis ball and a solid steel ball will accelerate at the same rate in the absence of air resistance is because the net force to mass ratio is the same for both objects.
<h3>
What is air resistance?</h3>
Air resistance is described as the forces that are in opposition to the relative motion of an object as it passes through the air.
The units for the force of air resistance are in Newtons (N).
Air resistance can be gotten by taking air density times the drag coefficient times area all over two, and then multiply by velocity squared.
So we can conclude that in the absence of air resistance, the horizontal velocity of the body is unaffected by any other external force as the only force which acts on the ball is gravity.

Answer:
Vector is a measurement that refers to both the magnitude of the unit and the direction of the movement the unit has taken.
