] Light of wavelength 500.0 nm in air falls at normal incidence on an oil film that is 850.0 nm thick. The oil is floating on a water layer. The refractive index of water is 1.33, and that of the oil is 1.40. You want to add oil so that light reflected from the oil film will be canceled. What is the minimum thickness of oil film you need to add

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

Ultra-high temperature (uht)

The object needs to be bigger than you, or (most people would say) you’d be attracting it. no matter how small an object is, if it has mass, it has gravity.
