While looking at her image in a cosmeticmirror, Dina notes that her face is highly magnified when she isclose to the mirror, but as she backs away from the mirror, herimage first becomes blurry, then disappears when she is about28.0 cm from the mirror, and theninverts when she is beyond 28.0 cm. Based on these observations,answer the following questions about the mirror.
What is the focal length of themirror?
f= cm
What isthe radius of curvature of the mirror?
R= cm
Under favourable circumstances the human eye can detect 1.0e-18 J of electromagnetic energy. How many 600-nm photons does this represent.
The famous horse & cart physics scenario is explained. This scenario is used to describe why many people have a common misconception about what Newton’s 3rd Law says & does not say.
A uniform rod of mass 3.20×10?2 and length 0.430 rotates in a horizontal plane about a fixed axis through its center and perpendicular to the rod. Two small rings, each with mass 0.190 , are mounted so that they can slide along the rod.
