Th answer is it could gain or loss magnetism.
Ferromagnetism is a kind of magnetism that is associated with cobalt, iron, and nickel and on some alloys or compounds containing one or more of the said elements, It also occurs in gadolinium, which is a rare-earth element. In comparison to other substances, ferromagnetic materials can be magnetized easily and in strong magnetic fields, the magnetization approaches a definite limit called stauration.
If an external field is applied and subsequently removed which does not return the magnetization to its original state or value it is called hysteresis. When heated to a certain temperature (Curie point), which is unique for each substance, ferromagnetic materials would somehow lose their magnetic properties and cease to be magnetic. Once they would cool down, their magnetism would return.
Answer:
F = 195 N
Explanation:
F = GMm/d²
F = 6.67e-11(5.97e24)(24) / (7.00e6)²
F = 195 N
Answer:
The spacing between the planes of the crystal is 0.295 nm
Explanation:
Given:
λ = wavelength = 0.24 nm
θ = angle of incidence = 66°
The spacing d between the planes of the crystal is equal:
To solve this problem it is necessary to apply the continuity equations for which it is defined that the proportion of Area in the initial section is equal to the final section. In other words,
Where,
Cross sectional area at each section
Velocities of fluid at each section
The total area of the branch is eighteen times of area of smaller artery. The average cross-sectional area of each artery is 
Therefore the Cross-sectional area at the end is
Applying the previous equation we have then
The ratio of the velocities then is
Therefore the factor by which the velocity of blood will reduce when it enters the smaller arteries is 0.1349
