up West East down A ball is attached to a string and whirled clockwise in a vertical circle. The direction of centripetal force at the location indicated is: A) down B) up C) East D) West E) none of the above

If a person walks toward a plane mirror at a speed 2 m/s, his image formed by the mirror will appear to "walk" at a spped Group of answer choices 2 m/s 4 m/s 3 m/s 1 m/s

Question is in the image

In the graphical method, a ray approaches a mirror parallel to the optical axis will     reflect off the mirror toward or away from the focus.     reflect off the mirror parallel to the optical axis.     reflect off the mirror with a reflection angle different from the incidence angle.     reflect off the mirror toward or away from the center of curvature.

what's the correct answer: A virtual image is an image thata) is not sharpb) is stored in a computerc) can be seen only by looking through an optical systemd) can be seen by placing a screen in the image planee) is displayed on a computer monitor

When the object distance from a concave mirror is greater than the focal distance, the image is Group of answer choices real and erect. real and inverted. perverted and inverted. virtual and erect.

Why does a sculpture three dimensional?

A coin is 12 cm in front of a converging lens with focal length of magnitude 4.0 cm. Where is the image? A) 8.0 cm behind the lens B) 6.0 cm in front of the lens C) 6.0 cm behind the lens D) 4.0 cm in front of the lens

The question is in the image thank you

An image formed by a concave mirror is mostly (except for cases when the object is placed too closed to the mirror) real and inverted real and straight / erect virtual and straight virtual and inverted
