Answer: B. Turning on your hazard lights.
Explanation:
Because...
that indicates the drive behind you to go in front of you and indicator lights that flash in unison to warn other drivers that the vehicle is a temporary obstruction.
* Hopefully this helps:) Mark me the brainliest:)!!!
Explanation:
A material can convert from ductile into brittle material by following reasons
1.At low temperature
2.Due to notches present in materials
When temperature is very low then a ductile material starts to behave like brittle material and it leads to failure of the material.
When material consists large number of notches then it losses it ductility and behave like brittle materials.
During the world war second ships are failed because temperature of sea became to low and due to this steel (ductile material) converted into brittle material and failed without giving any warning.
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
