Object O1 is 15.0 cm to the left of a converging lens of 10.0-cm focal length. A second lens is positioned 10.0 cm to the right of the first lens and is observe to for a final image at the position of the original object O1. Using numerical methods:
(a) What is the focal length of the second lens?
(b) What is the overall magnification of this system?
(c) What is the nature (i.e., real or virtual, upright or inverted) of the final image) of the final image?
(d) Draw a scaled ray diagram to confirm your numerical solution.
A glass window pane is exactly 20 cm by 36 cm at 10oC. By how much has its area increased as it temperature is 33oC, assuming that it can expand freely? Take the coefficient of thermal expansion for the glass to be exactly 9 x 10-6/Co.
An emf is induced in a conductin loop of wire 1.03 m long as its shape is changed from square to circular. Find the average magnitude of the induced emf if change in shape occurs in 4.15s and the local 0.131-T magnetic field is vertical to the pla..
A skier is accelerating down a 30 degree hill at 3.60 m/s^2. How long would it take her to reach the bottom of the hill, assume she starts from rest and accelerates uniformly, if elevation change is 170m.
A stone is thrown upward with an initial speed of 20 m/s. What is its acceleration at the highest point of its trajectory?
A large wheel starts from rest and has a constant angular acceleration of 3.5 radians/second^2. Determine the total angular displacement of the wheel during this motion
Consider an electron moving with a speed of 8.60 106 m/s at right angles to a constant magnetic field, with B = 1.9 T
A two-ended "rocket" that is at first stationary on a frictionless floor, with its center an origin of an x axis.
Three point charges, q1, q2, and q3, lie along the x-axis at x = 0.0 cm, x = 3.0 cm, and x = 5.0 cm, respectively. Calculate the electric force on q2
The Sun is a low mass star and so would never have the core fusion reactions of massive stars. Yet, the Sun has iron in its atmosphere, as well as gold, silver and other elements much heavier than iron and why?
Use Ampere's Law to find the magnetic field outside a long cylindrical conductor of radius R carrying a total current I from one end to the other
A continuous line of charge lies along an x axis, extending from x = +x0 to positive infinity. The line carries charge with the uniform linear charge density λ0. What are the magnitude and direction of the electric field at the origin.
A 59.0 kg skateboarder wants to just make it to the upper edge of a "quarter pipe," a track that is one-quarter of the circle with a radius of 3.80 m.
