A cannon with a muzzle velocity of 500. meters per second fires a cannonball at an angle of 30.° above the horizontal. What is the vertical component of the cannonball's velocity as it leaves the cannon? 0.0 m/s

250. m/s

433 m/s

500. m/s

250. m/s

Explanation:

It is vertical component so you do: 500mSin(30°) = 250m/s

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
