White Light

As a form of energy, light has specific properties such as color and brightness. Some properties can only be seen with special tools. Think about properties of light and how color in white light can be investigated.

Which statements are true about light properties and how color in white light can be investigated?

White light can be separated using any glass object.
Light travels in a straight line until it strikes an object.
When white light is separated by a prism, the colors appear in a random order.
The way light reacts when it strikes an object depends on the properties of that object.
When a single-colored light passes through a prism, it becomes white.
As white light passes through a prism , it bends and separates into different colors

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
