Torque on a Current Loop in a Magnetic Field
Learning Goal:
To understand the origin of the torque on a current loop due to the magnetic forces on the current-carrying wires.This problem will show you how to calculate the torque on a magnetic dipole in a uniform magnetic field. We startwith a rectangular current loop, the shape of which allows us to calculate the Lorentz forces explicitly. Then wegeneralize our result. Even if you already know the general formula to solve this problem, you might find itinstructive to discover where it comes from

ANSWER:
=CorrectNow, instead of electrons, suppose that the free charges have
positive
charge . Examples include "holes" insemiconductors and positive ions in liquids, each of which act as "conductors" for their free charges.
Part B
If one replaces the conducting cube with one that has positive charge carriers, in what direction does the inducedelectric field point?
ANSWER:
CorrectThe direction of the electric field stays the same regardless of the sign of the charges that are free to move in theconductor.Mathematically, you can see that this must be true since the expression you derived for the electric field isindependent of .Physically, this is because the force due to the magnetic field changes sign as well and causes positive charges tomove in the direction (as opposed to pushing negative charges in the direction). Therefore the result isalways the same: positive charges on the side and negative charges on the side. Because the electric fieldgoes from positive to negative charges will always point in the direction (given the original directions of</span>
Answer:
The correct answer is B. causes environmental acidification due to production of sulfuric acid.
Explanation:
Sulphur causes environmental acidification due to production of sulfuric acid. For example,
Sulphur can be oxidized to sulphur dioxide according to the equation:
S +O2 ==> SO2
The sulphur dioxide combines with rain water and is washed down in form of weak acid according to the equation;
SO2 +H2O ==> H2SO3
The product is an acid known as trioxosulphate (V) acid which is a sulphuric acid. And so acidification of environment is possible.
Also as Sulfur can be found in the air in many different forms. It can cause irritations of the eyes and the throat with animals, when the uptake takes place through inhalation of sulfur in the gaseous phase. Sulfur is applied in industries widely and emitted to air, due to the limited possibilities of destruction of the sulfur bonds that are applied.
The damaging effects of sulfur with animals are mostly brain damage, through malfunctioning of the hypothalamus, and damage to the nervous system.
Answer:
D. gravity, friction, and an applied force.
Explanation:
There are 4 forces that act on an airplane in motion and they are:
Gravity and drag:
It acts in a downward direction—toward the center of the Earth.
Lift:
It is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.
Thrust:
It is the force that propels a flying machine in the direction of motion.
