Consider two forces F1 and F2 of magnitudes 5N each pulling at an object lying at the origin. F1 is directed along the X-axis, whereas F2 is directed along Y-axis. Determine the resultant force (magnitude and direction) experienced by the object.

If steel is more dense that lake water, why can a boat float

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
