Q. Establish the speed of transverse waves on a string under a tension of 80.0 N if the string has a length of 2 m and a mass of 5 g. (b) Calculate the power required to create these waves if they have a wavelength of 16 cm and an amplitude of 4 cm.

Q. A curve of radius 50m is banked at an angle of 25 degree. If the coefficient of static friction between the road and the car is 0.3, what are the maximum and minimum speeds the car can have without skidding? Find the accurate speed of the car that does not need any friction force to prevent skidding.
