Consider a Young's two-slit experiment in which the wavelength of light is 37% smaller than the distance between the slits. How many complete dark fringes would be seen on a distant screen? (Assume for all these questions that the screen is as large as it needs to be.)

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

Need in all of themmm only answer if you know plsssss

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
