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.

Answer:
1 NAND gate
Explanation:
The minimum number of 2 input NAND gates that can be used to implement the combinational circuit = 1
The only true combinations conditions that can produce a false result ( i.e. condition/result different from the expected result as stated in the question )
Sensor 2 activated + Emergency switch pressed = False ( Line will keep moving )
The calculated answer is 4 kgf. The greatest resisting force that the walnut may exert before the nut cracks
In physics, resistive force is a a type of force, or the vector sum of the various forces, whose direction is opposite to the motion of a body, and may refer to: Friction, during sliding and/or rolling. During moving through a fluid, drag (physics) (see fluid dynamics). For all compression positions, the direction of specific deformation as a function of shell thickness and geometric mean diameter was identical to the direction of energy.
If load is 40 kgf and effort is?
effort arm=20 cm, load arm=2 cm
By the moments' principle,
effort arm equals load arm.
40kgf×2cm=E×10cm
∴E=40×220kgf=4kgf.
