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) Choose a point on any nodal line and show the complete calculation for wavelength. How does it compare to the value for wavelength given in the simulation PS1 -PS2 = n lambda?
