If two particles are moving towards each other and both particles have a strong positive charge, the both particles will repel each other and the forces will act away from each other.
When two charges approach each other, the magnitude of electrical force that acts between then depends on the nature of the charges. If the charges are like charges, they forces repel each other if they are unlike charges, the forces repel each other.
Hence, if two particles are moving towards each other and both particles have a strong positive charge, the both particles will repel each other and the forces will act away from each other.

(Fill in the blanks)For every force there is one that is_____in size but _________in direction.
Answer: For every force there is a reaction force that is equal in size, but opposite in direction.
Hope it helps:)
For every force, there are 2 components one that is equal in size but opposite in direction.
What is force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

Look at the diagram below.
Ray 1 from the Sun moves through air and falls on the surface of a lake. Ray 2 is a ray which travels from the surface of the lake at the point Ray 1 strikes the lake, and moves towards air. Ray 1 and Ray 2 make the same angle with the surface of the lake. Ray 1 bends towards the vertical when it enters the lake as Ray 3
(Ik this isn't physic's but its the closest i could find)

Describe characteristics and identify oxidation-reduction(redox) reactions.
plz and thx
Answer:
I hope This helps
Explanation:
The majority of oxidation-reduction (redox) reactions share two critical features. One is that a reduction happens in both, while equivalent oxidation occurs; they are combined.
The oxidation - reduction (redox) reactions has the characteristics of changes in oxygen, hydrogen and electrons.
What are the characteristics and identify oxidation - reduction (redox) reactions?Oxidation is the process during the reaction the reactant loses the electron. Reduction is the process during the reaction, the reactant gains the electron.
Redox reaction can be identified by knowing the number of oxidation. It can also be known through the atoms in this process should be bonded as ionic. During the reaction, the increase in oxidation number can be said as oxidation.
The different types of redox reactions are:

Holden is trying to determine the velocity of his race car. He went 20 meters east, turned around, and went 40 meters west. His car was 20 meters from the starting line. This took 5 seconds.
What is the car’s average velocity?
4 m/s east
4 m/s west
12 m/s west
12 m/s east
The average velocity can be found by calculating the total displacement of the car and dividing it by the total time.
The car's average velocity is "4 m/s west".
First, we will find the total displacement as follows:
Total Displacement = 20 m (East) + 40 m (West)
Taking East direction as positive and west direction as negative, we get:
Total Diplacement = 20 m - 40 m
Total Displacement = - 20 m = 20 m (West)
Now, the average velocity of the car will be:
[tex]Average\ Velocity = \frac{Total\ Displacement}{Total\ Time}\\\\Average\ Velocity = \frac{20\ m\ (West)}{5\ s}\\\\[/tex]
Average Velocity = 4 m/s west
The attached picture shows the description of average velocity.

How does centripetal force affect circular motion? A 24-N net force acts on an 8-kg rock. What is the acceleration of the rock?
Answer:
Part 1: As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. This would mean that the force is always directed perpendicular to the direction that the object is being displaced.
Part 2: So a = F / m or acceleration = Force / mass. You then just input your values, so 24 / 8. 24 / 8 = 3.
