The nose of an ultralight plane is pointed due south, and its airspeed indicator shows 35 m/s. the plane is in a 10-m/s wind blowing toward the southwest relative to the earth. (a) in a vector addition diagram, show the relationship of up/e (the velocity of the plane relative to the earth) to the two given vectors. (b) let x be east and y be north, and find the components of up/e. (c) find the magni- tude and direction of up/e

Which statement is true? a. kepler's laws apply only to the motion of earth. b. kepler's laws can be used to predict eclipses. c. kepler's laws are true for a central force that is directly proportional to distance. d. kepler's laws can be deduced from newton's laws of motion and gravity.

The graph represents the distance a car travels over time while on the highway. which statement about the car's trip is accurate? a) the car does not move over time. b) the car travels at a constant velocity. c) the car's velocity increases constantly over time. d) the car's velocity decreases constantly over time.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
