The complete question is;
A circular coil consists of N = 410 closely winded turns of wire and has a radius R = 0.75 m. A counterclockwise current I = 2.4 A is in the coil. The coil is set in a magnetic field of magnitude B = 1.1 T.
a. Express the magnetic dipole moment μ in terms of the number of the turns N, the current I, and radius
R.
b. Which direction does μ go?
Answer:
A) μ = 1738.87 A.m²
B) The direction of the magnetic moment will be in upward direction.
Explanation:
We are given;
The number of circular coils;
N = 410
The radius of the coil;R = 0.75m
The current in the coils; I = 2.4 A
The strength of magnetic field;
B =1.1T
The formula for magnetic dipole moment is given as;
μ = NIA
Where;
N is number of turns
I is current
A is area
Now, area; A = πr²
So, A = π(0.75)²
Thus,plugging in relevant values, the magnetic dipole moment is;
μ = 410 * 2.4 * π(0.75)²
μ = 1738.87 A.m²
B) According to Fleming's right hand rule, the direction of the magnetic moment comes out to be in upward direction.
The answer would be the one where the left side is less than or equal to 130 because 130 has to be the greatest value and the value of the w's cannot exceed 130, but they can equal it
Explanation:
According to the law of conservation of mass, the masses at the start and finish of a reaction will stay the same. The law of conservation of mass "mass is always constant in a chemical reaction".
- The law is the basis for chemical calculations.
- Masses of reactants and products must be the same to show that mass is always conserved.
- Disparity in the mass could result from loss of mass to the environment or some side reactions that cannot be easily monitored.

At the time of the Fall equinox (always near September 21),
and the Spring equinox (always near March 21), the days and
nights are nearly the same duration.
The shortest days of the year are around the Winter solstice ...
always near December 21.
The longest days of the year are around the Summer solstice ...
always near June 21.
Eclipses can happen on any day or night of the year. They're
totally not connected with the equinoxes or solstices.
