Humans can see electromagnetic radiation when the wavelength is within the spectrum of visible light. create a program to determine if a user-specified wavelength [nanometer, nm] is one of the six spectral colors listed in the following chart. your program should ask the user to enter a wavelength, then indicate in which spectral color the given wavelength falls or state if it is not within the visible spectrum.

On a average work day more than work place firs are reorted

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length
