In another experiment with springs, a large wave travels 10.2 m along a spring in 5.3 seconds. Approximately how much time would it take a small ripple to travel the same distance? * 1.9 seconds 4.9 seconds 5.3 seconds 10.2 seconds

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.
