Different kinds of lenses are used in eyeglasses to help people with eye conditions. Farsightedness is an eye condition in which distant objects appear clear but close objects appear blurry. Nearsightedness is an eye condition in which close objects appear clear but distant objects appear blurry.

Which best describes the type of lens that would help someone with one of these eye conditions?

Concave lenses would help someone who is nearsighted because the lenses make objects look smaller and closer.

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
