Block a has a mass of ma =137 kg and is at rest at the bottom (i. e. at the origin) of a frictionless 17 meter long ramp, inclined at some angle θinc. it is attached to block b, with mass mb, via a massless and inelastic string that passes up the ramp, over a massless and frictionless pulley, and then goes straight down to block b. block b is held in place and the system is initially at rest.

The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm(red) and 486 nm (blue). light from a hydrogen lamp illuminates a diffraction grating with 520lines/mm , and the light is observed on a screen 1.5m behind the grating. part a what is the distance between the first-order red and blue fringes? express your answer to two significant figures and include the appropriate units.

If y gets smaller as x gets bigger and y have an relationship?

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
