<h2>
Answer</h2>
The <u>electron affinity in chemical reaction</u> decides the formation of breakdown of substance
<h2>
Explanation</h2>
Within the chemical reactions, different reactants are come together to make the new compound to complete up to the reaction. The reaction is based on the stability of reactants and the electron affinity of these reactants. The oxidation and reduction process within the reaction is also the main reason to combine or break the substance. For example
The hydron has the ability to lose electron and fluorine has the ability to gain an electron. The strong or weak electron affinity of this element makes the new compound HF.
The electric field depends not on the magnetic field, but change in magnetic field. if the magnetic field is constant. electric field will be zero.
Answer:
We cannot tell from the information given
Explanation:
Given;
mass of the box, m = 5 kg
first force, F₁ = 10 N
second force, F₂ = 5 N
(I) Assuming the two forces are acting horizontally in opposite direction, the resultant force on the box is calculated as;
∑Fx = 10 N - 5 N
= 5 N
Apply Newton's second law of motion;
∑Fx = ma
a = ∑Fx/m
a = 5 / 5
a = 1 m/s² in the direction of the 10 N force.
(II) Also, if the two forces are acting in the same direction, the resultant force is calculated as;
∑Fx = 10 N + 5 N
∑Fx = 15 N
a = 15 / 5
a = 3 m/s²
Therefore, the information given is not enough to determine the acceleration of the box.
Our modern version which is a heliocentric model of the universe also supported by other scientists like Nicholas Copernicus and Johannes Kepler developed theories that conflicted with the Ptolemaic model of the universe developed by Ptolemy in ancient times which assume that the earth is the center of the solar system and all the stars and planets are revolving around it.
<h3>What is a solar system?</h3>
It is a system that collection of all the planets and spatial bodies revolving around the sun because of the gravitational pull of the sun.
Our Solar System is based on a heliocentric model in which the Sun is assumed to reside at the central point of the planetary system.
In other words, the Sun is at the center while the Earth and other planetary bodies revolve around it.
The geocentric model of the universe developed by Ptolemy in ancient times, which holds that the earth is the center of the solar system and that all the stars and planets revolve around it, was in conflict with our modern version, which is a heliocentric model of the universe and also supported by Nicholas Copernicus and Johannes Kepler.

Answer:
Angular speed ω=3771.4 rad/min
Revolution=5921 rpm
Explanation:
Given data
To find
Angular speed ω
Revolution per minute N
Solution
First we need to convert the speed of truck to inches per mile
as
1 mile=63360 inches
1 hour=60 minutes
so
Now to solve for angular speed ω by substituting the speed v and radius r in below equation
To solve for N(revolutions per minute) by substituting the angular speed ω in the following equation
