Which type of curved mirror uses its outside as the reflecting surface? a virtual mirror a concave mirror a plane mirror a convex mirror

a convex mirror

Explanation:

a convex mirror is a type of curved mirror that uses its outside as the reflecting surface;

A mirror whose reflecting surface curves outwards is called a convex mirror. In convex mirrors, the bulging portion is also the reflecting surface. These types of curved mirrors are widely used in vehicles as rear view mirrors since they are able to form diminished images and thus give us a larger view.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
