An object is located 5 cm to the left of a concave mirror that has a radius of curvature if 20 cm.
a) Calculate the image distance from the mirror.
b) What is the distance between the image and the object?
c) Claculate the magnification of the image and state wether the image is real or virtual; upright or inverted; and enlarged, reduced, or the same size as the object.
d) If the height of the image is 4 cm, find the height of the object.
e) Construct a ray diagram for this arrangment to locate the image (on a seperate graph paper draw three rays from the object to determine the location of the image) From your drawing, determine the image distance and show that it is consistent with what you found in part (a).
A force of F=9.0i+8.0jN is applied to an object about a fixed axis aligned with the z direction. If the force applied at the point (6.00 m, 9.00 m), illustrate what is the magnitude and direction of the torque?
illustrate what is the magnitude of the acceleration of the box and hanging mass?
