A lens is located 30 centimeter to the right of an object, with an image clearly focused on a screen 45 centimeter from the lens. When a second lens is placed 30 centimeter to the right of the first lens, the final image is shifted 15 centimeter to the right (so that it is now 60.0 cm from the first lens).
A) Evaluate the focal length of each lens.
B) Construct a ray trace to verify your calculations.
What is the maximum speed with which a 1060kg car can round a turn of radius 75m on a flat road if the coefficient of static friction between tires and road is 0.80.
An explorer is caught in a whiteout (in which the snowfall is so thick that the ground cannot be distinguished from the sky) while returning to base camp.
A non conducting solid sphere of radius 2.40 centimeter carries a uniformly distributed positive charge of 7.80E-9 C. Find the magnitude of the electric field at a point 3.10 centimeter away from the center of the sphere
