se the measurement tools to measure the period, frequency, and wavelength of the waves. Hint: To get an accurate measurement of the period, use the stopwatch to measure several oscillations and then divide to find the time for one oscillation.

The sun generates both mechanical and electromagnetic waves. which statement about those wave is true?

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)]

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1
