Answer:
true
Explanation:
true An electromagnet is formed when a coil of wire wrapped around an iron core is hooked up to a dry cell battery. The current traveling through the wire sets up a magnetic field around the wire. TRUE or FALSE
Properties of Carpenter's hammer possess
Explanation:
1.The head of a carpenter's hammer should possess the impact resistance, so that the chips do not peel off the striking face while working.
2.The hammer head should also be very hard, so that it does not deform while driving or eradicate any nails in wood.
3.Carpenter's hammer is used to impact smaller areas of an object.It can drive nails in the wood,can crush the rock and shape the metal.It is not suitable for heavy work.
How hammer head is manufactured :
1.Hammer head is produced by metal forging process.
2.In this process metal is heated and this molten metal is placed in the cavities said to be dies.
3.One die is fixed and another die is movable.Ram forces the two dies under the forces which gives the metal desired shape.
4.The third process is repeated for several times.
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.
