You need to build a prototype with machined parts that withstand a saline corrosive environment and temperatures above 200 degre
kondor19780726 [428]

Answer:

Stainless steel

Explanation:

I will try to order the solutions from the least correct to the most correct.

Since a temperature greater than 200 ° F is required, that is to say approximately 93 ° c, <em>Polycaprolactone</em> is the least indicated. Its melting point is approximately 60 ° C, so it would not serve the required application.

On the other hand we have<em> Untreated aluminum</em>, which although it has a melting point higher than the required one, without a zinc and magnesium treatment it will easily oxidize in a salty environment, so it cannot be used in this choice either.

We have to compare the two steels.

The<em> Mild Steel </em>has a better corrosion resistance than the previous ones, but in a long-term cycle it will end up full of corrosion and therefore its properties will be highly affected.

Finally, we have <em>stainless steel</em>, which, as the name implies, contains in some of its variations chromium, zinc or magnesium in its alloys, which makes it highly resistant to corrosion.

In addition its melting point is above 1500 ° c.

The best choice is stainless steel.

Radio waves travel at the speed of light, which is 3.00 u 108 m/s. How many kilometers will radio messages travel in exactly one
egoroff_w [7]

Answer:                

Distance traveled will be 9.462\times 10^{12}km

Explanation:

We have given speed of the light v=3\times 10^8m/sec

We have to find the distance traveled by light in 1 year

We know that 1 year = 8760 hour

And 1 hour = 60×60 = 3600 sec

So 1 year =8760\times 3600=3.154\times 10^{7}sec

We know that distance = speed × time

So distance traveled by light in one year =3.154\times 10^7\times 3\times 10^8=9.462\times 10^{15}m

We have to fond the distance in km

As we know that 1 km = 1000 m

So 9.462\times 10^{15}m=\frac{9.462\times 10^{15}}{1000}=9.462\times 10^{12}km
