Answer:
The value is [tex]I= 0.0597\ A[/tex]
Explanation:
From the question we are told that
The length of the solenoid is [tex]l = 15 \ cm = 0.15 \ m[/tex]
The number of turns is [tex]N = 100[/tex]
The magnetic field of the earth is [tex]B = 5* 10^{-5} \ T[/tex]
Gnerally magnetic field is mathematically represented as
[tex]B = \frac{\mu_o * N * I }{ l }[/tex]
=> [tex]I= \frac{Bl}{ \mu_o *N }[/tex]
=> [tex]I= \frac{ 5 *10^{-5} * 0.15}{4\pi *10^{-7} *100 }[/tex]
=> [tex]I= 0.0597\ A[/tex]

Why is the value of a substance’s specific gravity always the same numerically as its density?
Because it is always the substance’s density divided by the density of water which is 1 g/cm 3
Because it is always the substance’s density multiplied by the density of water which is 1 g/cm 3
Because specific gravity is the inverse of density
Because these represent the same measurement
Answer:
Because it is always the substance’s density divided by the density of water which is 1 g/cm 3
Explanation:
The density of water is 1g/cm³;
Specific gravity = [tex]\frac{density of substance}{density of water}[/tex]
Since specific gravity is a relative comparison of a substance density with that of water, the values always the same.
Density of water is 1 and it will have no effect on the density of the substance.
The only difference is in the units. The density of a substance will have a unit but that of the specific gravity will have no unit.
Numerically, dividing by 1 has no implication.
Answer: the answer is C
Explanation:Specific gravity is the density of a substance divided by the density of water. Since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density
