As a spacecraft enters the atmosphere, it will travel at a tremendously high speed. The friction from the air rubbing against the spacecraft causes lots of heat. To protect against this heat, spacecraft use heat shields. Most spacecraft use blunt, spherical, or conic heat shields which help slow the vehicle down, and dissipate the heat in the surrounding air. These heat shields are also usually made out of abalative material. Abalative materials sublimate into gas at high temperature. As a result, they absorb thermal energy but erode away as the vehicle enters the atmosphere. However modern spacecraft are being developed to have re-usable heat shields. The Space Shuttle, in particular, uses a series of thermal insulating tiles that absorb and radiate heat while preventing conduction to the shuttle's aluminum skin. These tiles can be re-used many times.

If your ACC fuse burns out when you do not heat up your car is it a wire?

A fuse blow when ever the amperage is to high for the circuit.Either there is a short (to ground or positive), the connectionsare corroded, wire gauge is too thin or it is the wrong fuse. Neverput in a fuse larger than recommend for the circuit, it could causea fire.

What is the resistance of the heating element in a kettle?

The heating element in the electric kettle will be primarily pure resistive. Power in that case is calculated P = E*I = 250V*I = 3000 W So the current is I = 3000 W/250 V = 12 Amps If there is anything else (lights, radio, PC, etc.) on the circuit that may be taking some current you are ver ( Full Answer )

Can polyester resist heat?

No, polyester cannot resist heat. No object can 'resist' heat of any kind. Polyester can resist heat up to a certain point, which may only be a few degrees, but no object can fully 'resist' heat.

Examples of resistive heating?

In a toaster, the house current from the outlet passes through a wire with some resistance.. Household electricity is supplied at a nominal 117 volts AC. If 'R' is the resistance of the wire in the toaster, then the power (heat) dissipated by the wire is E 2 /R. = (117) 2 /R watts of heat.. Notic ( Full Answer )

Why are some instruments heat resistant?

Only conductive instruments conduct heat, depending on the material of the instrument. E. g. metal is a good conductor, thus wouldn't be heat resistant.. If heat resistant means "still functioning despite the fact that it is hot" then many instruments made with metal parts are heat resistant. Metal ( Full Answer )

Why does heat increase electrical resistance?

Electrical resistance increases because the density of charge carriers decreases with increased temperature. High temperature resistivity is predominantly characterized by collisions between electrons and metal atoms. Decreasing the density of charge carriers increases resisistance.

What is the ability of a substance to resist burning?

If you're asking about what word it is, it's simply Inflammable. But if you're asking how they are Inflammable, then it would be because the molecules are moving just to slow in the object not on fire. By increasing the molecule movement speed, you increase the temperature, depending on how fast t ( Full Answer )

Why does the moon have extreme heat and extreme cold?

it has no atmosphere to distribute heat and no water to absorb and release heat. he earth's relatively consistent temperatures are caused by the fact that 70% of its surface is water, which absorbs large quantities of solar energy and releases it slowly back into the atmosphere as heat, while the a ( Full Answer )

How to calculate heat produced in the resistance?

1 V = 1 J / A * s.. If you know the current, the voltage, and the amount of time the circuit was in operation, then you can calculate the number of joules of heat produced.. Since a watt is a joule per second, you can also calculate it from the wattage if you have that information handy..
