The electrical resistivity depends only on the geometrical parameters of the conductive wire.

Given a body of mass 1,7 kg, hung on a wire, 9,9 mm in diameter.

Calculate the relative elongation if Young's modulus of the wire is 5427240 N/m2.

Enter your answer to four decimal places, use a dot to separate the decimal point.

Ceramics conduct heat and electricity well.

Determine the composition of Cu - copper - in the Zn-Cu alloy in atomic percent, give its answer in percent, to two decimal places.
If its composition in percentage by mass: Zn - 65,4%, Cu - 63,5%
If the molecular weight of the substances: Zn - 70 g / mol, Cu - 30 g / mol

The value of the elastic stress is directly proportional to the value of the surface affected by the force.

The nucleus consists of electrons, protons, and neutrons.

Determine the mass composition of tin in the Pb-Sn alloy, give it as a percentage to two decimal places.

If its composition is Pb - 6 at%, Sn - 94 at%.

While the molecular weights of the materials are: Pb - 207,2 g / mol, Sn - 118,7 g / mol
