The diagrams show objects' gravitational pull toward each other. Which statement describes the relationship between diagram X and Y? х Gravity attracts only larger objects toward one another. Gravity attracts larger objects only if they are close to one another. If the masses of the objects increase, then the force between them also increases. If distance between the objects increases, then the amount of force also increases. Y Z

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
