An observer with a near point of 25cm looks through a microscope with an objective lens of focal length 1.2cm. when an object is placed 1.28cm from the objective, the angular magnification is -198 and the final image is formed at infinity a. What is the tube length of the microscope b. What is the focal length of the eyepiece
You are on a clothoid roller coster upside down at the top of a loop with an accelerometer.
The radius of the loop's curvature is 18 m. You experience a force of 2.0 times your normal weight from your seat.
a) Identify the forces acting on the accelerometer
b) What reading will you observe at the top of the loop if the accelerometer is calibrated as in the image above?
c) If you actually tried to use an accelerometer like the one shown in the image above on a roller coaster, what likely sources of error would you expect?
2. A clothoid loop in a roller coaster has the same height as a circular loop but half the radius at the top. A rider at the top of either loop typically experiences a net force of 1.5mg. What is the ratio of the speed at the top of the circular loop to the speed at the top of the clothoid loop?
Find work done on a body if, force = 2x² and displacement=5
