1) car rounds a frictionless corner with a radius of 5.5 × 10^2 m. The
corner is banked at an angle of 5.7º. find the speed of the car as it rounds the corner
2) Why is the electrostatic force greater than the gravitational force ? Explain please.Thanks
3) Do sound waves having higher frequencies travel faster or slower? Why?
4) An 1-cm tall object is located 4 cm from a converging lens that has a focal local length of
1.33 cm. Use a ruler and be mindful of the scaling.
a) Draw a ray tracing diagram with all three special rays to find the image. Measure the object
image distance and the image height with a ruler and record their values. Label the optical axis,
the object, the image, the near focal point, and the far focal point. Indicate the object distance,
the image distance, and the focal lengths on your diagram.
b) Use the thin lens equation to find the image distance, the image height, and the
magnification of the image. Is the image real or virtual? Is the image upright or inverted?
