Experiment to show that a dark surface is a ggod absorber of radiation while a white surface is a bad absorber of radiation?

Paint two otherwise identical objects, one with white paint, the other with black paint. Put both of them in the sunshine. The black object should get hot faster than the white one, because the absorbed heat energy gets converted to heat.

How does energy produced in the core of the sun reach the surface how long?
Mainly by radiation - however, the radiation quickly gets absorbed by an atom, and re-emitted, so it takes quite a while to reach the surface. In the outer part of the Sun, the energy also gets transported through convection.
Is dull surface a good radiator of heat?
It is in fact the best radiator. Dull black is the best absorber and emitter. Then shiny black, followed by white, then silver. While the best reflector goes the other way around (silver's the best, then white, followed by shiny black, then dull black)
Why do flat maps distort Earth's surface?
They distort the surface because they are flat, while the surface is not.
What should you use to record your data while carrying out an experiment?
A NoteBook
What is a hypothesies?
An educated guess based on your five scenes while observing an experiment or activity.
What is the difference between a UV stabilizer and a UV absorber?
One stabilizes the engine while an absorber absords any excess heat.
Which is the better reflector of light a black surface or a white surface?
A white surface because black absorbs the light, while white while reflect it. A good experiment is to wear a black shirt outside and a white shirt outside and see which makes you hotter in the sun

How do you change shock absorbers in 2002 dodge caravan?
# Raise vehicle. # Support the rear axle of the vehicle using 2 jackstands positioned at the outer ends of the axle. NOTE:If the shock absorber lower mounting bolt deflects upward during removal, raise axle by adjusting the support jack. If the lower shock absorber bolt deflects downward during removal, lower the axle by adjusting the support jack. # Remove the shock absorber lower mounting bolt. # While holding shock absorber, remove the shock absorber upper mounting bolt and shock absorber. # While holding shock absorber in position against the frame rail, install the shock absorber upper mounting bolt. # Install the shock absorber lower mounting bolt securing the lower end of the shock absorber to the axle. # Remove the support jack. # Lower the vehicle to the ground so the full curb weight of the vehicle is supported by the suspension. # Tighten the upper and lower shock absorber mounting bolt to a torque of 88 N·m (65 ft. lbs.).
Radiation symtoms can result from a single exposure and are contagious?
While radiation symptoms can occur from a single, prolonged, exposure, the symptoms of radiation are not contagious.

What are necessary precautions for safety purposes while conducting an experiment?
The necessary safety precautions when conducting an experiment depend on what is done during the experiment and where it is done.
Why is ultraviolet radiation capable of producing this damage while visible radiation even if more intense does not?
Ultra violet radiation has more energy (E=hf) than visible radiation.
