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?
5) The following pulse input signal feeds into a "mystery circuit" which
consists of a single op-amp. Supplies are v+=+l5V and v-= -15V. Assume ideal opamps. Further assume that if the output of an op-amp clips the output level is equal to the respective supply voltage. Find what the mystery circuit is, draw it and suggest suitable component values.
