Answer:
P = 2 pi (L / g)^1/2
P2 / P1 = (8 / 2)^1/2 = 2
The period would be twice as long or 5.6 sec.
Information provided:
Length of wire, L = 320 m
Current through the wire, I = 120 Amps
Earth's magnetic field acting on the wire, B = 5.0*10^-5 T
Angle at which the magnetic field acts, Ф = 60°
By definition;
Force on the wire, F = LBI Sin Ф
Substituting;
F = 320*5*10^-5*120*Sin 60 = 1.663 N
Physical property
Dissolve
Explanation:
A physical property of salt is that it will dissolve in water.
A salt is an ionic compound consisting of positive ions such as metallic, ammonium and complex ions and negative ions such as acid radicals and complex ions.
The physical property of substance tells us everything about a substance when no change is occurring to its constituents.
- Solubility is an example of physical property of matter.
- Generally, like substances will dissolve one another.
- Salt is an ionic compound, and like water, it is polar.
- Water molecules will aggregate round each salt particle and hydrate them into solution.
