Which best describes the type of lens that would help
someone with one of these eye conditions?
O Concave lenses would help someone who is
nearsighted because the lenses make objects look
smaller and closer.
O Concave lenses would help someone who is farsighted
because the lenses make objects look smaller and
closer
O Convex lenses would help someone who is nearsighted
because the lenses can make objects look smaller and
closer
O Convex lenses would help someone who is nearsighted
because the lenses can make objects look larger and
farther away

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s

Aquarterback pedals 3.3meters southward and then run 5.7meters northward. whats the distance ? and whats the displacement?

Which changes would result in a decrease in the gravitational force btween two objects? check all that apply
