A & B
Observe the path of the light ray as it passes through the lenses as shown in the attached images. Concave lenses diverge light rays while the convex lens converges the light rays.
Explanation:
Real images are formed where the rays converge, a property of images by convex lenses. Convex lenses can be used to magnify objects. If the image occurs before the focal point of the lens then the image will be upright but smaller. The images inverts and gets bigger past the focal point.
Virtual images are property of concave lenses. These images appear closer but smaller than the real object.

not too sure on this one maybe to locate objects under water, to diagnose problems, to treat medical ailments
Answer:
Step by step explanation
Step 1
In this step we use the definition of acceleration to determine the expression to integrate. Note that the acceleration is the derivative of velocity with respect to time.
Step 2
Perform integration on the expression from step 1. This calculation is performed as shown below.
Step 3
In this step we use the condition that at 
, the velocity 
to find the exact form of the velocity function. We substitute this point into the velocity function we found in step 2.
Step 4
We now use the function in step 3 to find out when the velocity is zero again.
The velocity is zero again when
