From what we know, we can confirm that this ratio (turning up the volume by one click relative to the TV's overall volume) can be quantified as the Weber fraction.
<h3>What is the Weber fraction?</h3>
This fraction describes the ratio needed for change to a stimulus in which the change is just barely noticeable. This question is a prime example in that it seeks to find out just how low of a difference is needed in TV volume in order for the difference to be noticeable.
Therefore, we can confirm that this ratio (turning up the volume by one click relative to the TV's overall volume) can be quantified as the Weber fraction.

Answer:
25 x 9/5 = 45 degrees Fahrenheit
Explanation:
(1) Doubling of the current through the wire will result in doubling of its magnetic field.
The magnetic field around a wire is a function of the current I and radial distance r
(with mu denoting the magnetic permeability of the medium). So, B is directly proportional to I. The field magnitude will double with the doubled current from 5A to 10A
(2) Using the same formula as in (1), we can see that the magnetic field is inversely proportional to the radial distance from the wire. So, a particle at 20cm will experience half the magnitude compared to a particle at 10cm.
(3) Answer
If a particle with a charge q moves through a magnetic field B with velocity v, it will be acted on by the magnetic force
So, a particle with charge -2uC will experience a magnetic force of same magnitude but opposite direction (and perpendicular to B) as compared to a particle with a charge of 2uC
Mass and gravitational field
Answer:
Explanation:
Both increase in temperature and availability of water drives physical and chemical weathering and increases their rate.
Increase in temperature causes rocks to expand and molecules are more free to move about. Constantly heating and cooling of a rock can lead to mechanical fracturing or cracks developing.
A high amount of rainfall facilitates chemical weathering. Chemical weathering is the decomposition of rocks.
The main agent that is important for natural chemical processes to occur is the presence water.
Water contains some other dissolved substances in it.
This is evident in tropical regions of the world
