What are poor radiators of heat?
The poor radiants of heat mean bad conductors of heator insulators.we can see that anything which is not a metal are poor radiants of heat. For examplewoodplasticploysteyene foamgelfabricsgasnichromiumi hope you got the answer
How can 2 objects that are the same temperature feel as if they are different temps?
The difference may be due to different conductivity. For example, if you touch hot metal, heat flows from the metal to your fingers. Because of the metal's good conductivity, more heat will quickly replenish the heat the metal has lost - the heat will flow quickly to your fingers. Do the same with glass (a bad conductor), and only a small amount of heat will flow. The glass in contact with your skin will quickly have the same temperature as your skin.
When is it bad to have a lot of friction?
Having a lot of friction can be bad when you want smooth motion between two surfaces, as it can cause heat, wear, and energy loss. In some cases, high friction can also lead to difficulties in moving objects or machinery.
Is sand a good or bad heat conductor?
Sand is a poor heat conductor compared to materials like metal. This is because sand is a poor conductor of heat due to its low thermal conductivity. This property makes it suitable for protecting objects from high temperatures.
Describe good and bad effects of friction?
Some of the good effects of friction are also the bad effects.Good effects:Stops or immobilises objects including cars, trucks and humans from sliding down a slope;Allows humans to walk - pushing off from the back foot and not falling over (think about walking on ice or worse, running on ice);Allows objects to remain where they are ie remain at rest, to be leant on;...Bad effects:Causes the production of heat between surfaces when the objects move eg car tyres and brakes heat up due to friction. Engines have to be oiled to reduce the friction of the moving parts. If the engine runs out of oil then the motor will seize due to friction (did that once - new engine required);Friction causes wear on surfaces that slide on one another - even our shoes wear out due to friction with the ground;Friction with air causes air craft, rockets and meteors to heat;...
Why is a poor reflector of heat also a good absorber?
Common sense. Is something is reflected, it cannot be absorbed, and vice versa. If something is a good absorber of heat, it tries to "hold onto" as much heat as possible; if something is a poor reflector of heat, it is bad at minimizing heat absorption.

Is it bad that the radiator's exhaust pipe has a hole?
Radiators do not have exhaust.
What is the rattle underneath in the left rear corner of your 2000 grand cherokee?
Could be a bad shock absorber or shock absorber bushing. Could be bad bushings on the rear sway bar (if equipped).
What is conductors and insulators?
Conductors are good absorber of heat whereas insulator are bad absorber of heat .Examples of conductors are silver,copper,etc..and example of insulators are plastic,ebonite,etc...
Why silver tea pots is preffered to black tea pots?
Because silver teapots reflect the heat that is coming from the liquid therefore bouncing off the sides of the kettle and keeping the liquid warm. Whereas a black kettle would just absorb the heat which wouldn't keep the liquid warm. Also, silver is a bad absorber and a bad emitter.
Why are firearms bad?
Inanimate objects are neither good or bad, they are just objects. People are good or bad and use objects in either good or bad ways.
Why is a petrol tanks painted silver?
This is bcoz the fuel inside is highly flammable and shiny white or silvery surface help to keep it cool and prevent it to blow everything around in tiny chunks :) As such surfaces reflect radiation and are a bad absorber of heat.
What does the thumping sound coming from underneath a van and vibration mean under the driver side?
check for a bad shock absorber or even a bad u-joint in drive shaft
Does a bad steering damper on a 2001 dodge ram 4x4 cause loss of power steering?
No, the damper is just a shock absorber.

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.
