Answer:
a) 152000 slugs
b) 2220000 kg or 2220 metric tons
Explanation:
A body with a weight of 4.9*10^6 lbf has a mass of
4.9*10^6 lbm * 1 lbf/lbm = 4.9*10^6 lbm
This mass value can then be converted to other mass values.
1 slug is 32.17 lbm
Therefore:
4.9*10^6 lbm * 1 slug / (32.17 lbm) = 152000 slugs
1 lb is 0.453 kg
Therefore:
4.9*10^6 lbm / (1/0.453) * kg/lbm = 2220000 kg
Answer:
stainless steel
Explanation:
Conductivity refers to the degree to which a specified material conducts electricity. It is the ratio of the current density in the material and the electric field.
The thermal conductivity of a material measures its ability to conduct heat.
In materials of low thermal conductivity, heat transfer occurs at a lower rate as compared to materials of high thermal conductivity.
Thermal expansion of the material refers to its tendency to change its shape, area, and volume as a result of change in temperature.
The electrical resistance of a material refers to the measure of its opposition to the flow of electric current.
<u>Stainless steel</u> has a lower coefficient of thermal conductivity along with a higher coefficient of thermal expansion and higher electrical resistance.
