How does the speed of light depend on an observer's frame of reference? a. the speed of light is faster when observed from a frame of reference that is not moving b. the speed of light is the same regardless of the frame of reference c. the speed of light is slower when observed from a frame of reference that moves close to the speed of light d. the speed of light depends on the acceleration of the frame of reference

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Consider the growth of a 20-nm-diameter silicon nanowire onto a silicon wafer. the temperature of the wafer surface is maintained at 2400 k. assume the thermal conductivity of the silicon nanowire is 20 wm-1k-1 and all its surfaces including the tip are subjected to convection heat transfer with the coefficient h = 1×105 wm-2k-1 and t∞ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =

Suppose you plot the distance traveled by an object at various times and you discover that the graph is not a straight line. what does this indicate about the object's acceleration?
