Answer: change the tires
Explanation: you can’t drive on a flat tire
Answer:
a. 2.9218x10^(-29) m^3
b. 7.1230x10^(28) atoms/m^3
c. 2.0812 BM/atom
Explanation:
Atomic radius r = 0.154 nm
saturation flux density Bs = 0.83 tesla
- the formula for the volume of the simple cubic crystal (Vc) = a^3 = (2r)^3
= (2 x 0.154x10^-9)^3
= 2.9218x10^-29 m^3
- The formula for the Bohr magneton per atom with respect to VC, Bs, permeability of the vacuum Uo and magnetic moment per Bohr magneton Ub is;
Bohr magneton per atom nb = (Bs x VC) / (Ub x Uo)
= (0.83 x 2.9218x10^-29) / (9.27x10^-24) x(1.257x10^-6)
= 2.4251x10^-29 / 1.1652x10^-29
= 2.0812 BM/atom
- Number of atoms per Vc, N = nb / Vc
= 2.0812 / 2.9218x10^-29 = 7.1230x10^28 atoms
Answer:
Alloying (co -depositing)
Explanation:
Coating:
Coasting is a process to protect the metal from corrosion and other defects. Due to presence of moisture in the atmosphere one layer of oxide form on the surface of metal and due to this metal loos it strength.
Steel is coated by tin to prevent the steel from rust . Alloying is the best method for tin coating .Generally alloys like tin lead,tin copper etc.
Answer:
Potential energy.
Explanation:
Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.
I hope this helps have a great day :)
