Aspring is stretched to a displacement of 3.4 m from equilibrium. then the spring is released and allowed to recoil to a displacement of 1.9 m from equilibrium. the spring constant is 11 n/m. what best describes the work involved as the spring recoils?

Adouble-slit experiment is performed with light of wavelength 600 nm. the bright interference fringes are spaced 1.8 mm apart on the viewing screen.what will the fringe spacing be if the light is changed to a wavelength of 400 nm? ?

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.
