What are the two main
categories of particles and
antiparticles?
Answer:
Particles can be classified as hadrons – baryons and mesons – and leptons, each with its anti-particle, and they should know that interactions between these particles can be described in terms of transfer of other particles known as vector bosons.

Benjamina started her walk from the front door of her ground-floor apartment. She walked 6 meters to the corner of the building and then turned the corner and walked 10 meters to her friend’s apartment. Identify the difference between the distance she walked and her displacement.
Answer:
The change in her position (from beginning to end), along with the direction, is considered her displacement.
Explanation:
Answer:
The change in her position ( from beginning to end), along with the direction, is considered her displacement. This value is a measurement and a direction. The total distance along the path from her starting point to her endpoint is considered her distance. This value is a measurement only.

Psychology is not considered a natural science. While it deals with the study of the human mind and behavior, psychology is generally classified as a social science rather than a natural science.
What are natural sciences?Natural science is a branch of science that deals with the study of the natural world, including the physical, chemical, and biological aspects of nature. It is a systematic and empirical approach to understanding the natural phenomena that occur in the universe. Natural sciences include subjects such as physics, chemistry, biology, geology, and astronomy, among others.
These sciences use the scientific method to investigate and explain the behavior of the natural world, relying on observation, experimentation, and analysis of data to formulate theories and laws that can explain natural phenomena. Natural science plays a critical role in our understanding of the universe and has contributed immensely to technological advancements in various fields. Therefore, option (B) is correct.

A wheelbarrow of mass 20 kg accelerates from rest and reaches speed of 10m/S2 in 5 seconds.its force?
Answer:
[tex]\boxed {\boxed {\sf 40 \ Newtons}}[/tex]
Explanation:
We are asked to find the force of a wheelbarrow. According to Newton's Second Law of Motion, force is the product of mass and acceleration.
[tex]F= \ m \times a[/tex]
1. Calculate AccelerationThe mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.
[tex]a= \frac{v_f-v_i}{t}[/tex]
The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).
[tex]v_f=[/tex]10 m/s [tex]v_i=[/tex]0 m/s t= 5 sSubstitute these values into the formula.
[tex]a= \frac{ 10 \ m/s-0 \ m/s}{5 \ s}[/tex]
Solve the numerator.
[tex]a= \frac{10 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= 2 \ m/s/s[/tex]
[tex]a= 2 \ m/s^2[/tex]
2. Calculate ForceNow we know the mass and acceleration of the wheelbarrow
m= 20 kg a= 2 m/s²Substitute the values into the force formula.
[tex]F= 20 \ kg \times 2 \ m/s^2[/tex]
[tex]F= 40 \ kg*m/s^2[/tex]
Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our answer of 40 kilogram meters per square second is equal to 40 Newtons.
[tex]F= 40 \ N[/tex]
Answer:
40 N
Explanation:
We know that
F = ma
and
a = (v - u)/t
So,
F = m(v - u)/t
F = 20(10 - 0)/5
F = 20(10/5)
F = 20(2)
F = 40 N

In vector diagrams, what does the length of the arrow tell you?
Answer:
The length of the arrow tells you the size of the quantity in the vector diagram.
The direction of the arrow simply tells you the direction
Answer and Explanation:
A vector in this sense is a thing that has both magnitude (length) and direction.
Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.
This doesn't give any information about where you started or any information about where you ended up after those 2 hours.
This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.
Velocity is a vector.
Look on a map at where you are right now. Call that the center of the circle. Draw the circle with a 10 mile radius around where you are now.
The length of the arrow represents all of the possible places you could be after a two hour walk.
Which direction the arrow was pointing is what allows your friends to meet you there without checking along a ~63 mile path to find you or searching ~314 square miles to find you if you slowed down or stopped off along the way.
Does a fan that is not spinning have energy?
Answer:
Yes, when dealing with electricity as long as there is an input source there is always built up energy waiting to be used also known as kinetic energy. The fan is not spinning but if it were turned on it would spin instantaneously.
Explain an experiment you could run to test the Big Bang theory, including the design and execution, and any observations you can make of the world around you related to the scientific theory. And explain how the observations support of refute the theory!!! Will mark branliest
The big bang theory or great expansion explains the formation of the universe from a point with very high density where matter and space were created, it can be observed in an experiment
The Big Bang theory that can be adapted with some home experiments, specifically the expansion can be measured using an experiment with inflating balloons.
Materials
deflated balloons
marker
thread
measuring tape
Description of the experiment
The stars or galaxies are marked repeatedly with an initial separation and this distance is measured by a thread the length and the thread with a meter, this is used as measured by the fact that the surface is curved.
The balloon is inflated and measurements of the separation are made, observing that as the volume of the balloon increases (time increase) the separation of the galaxies increases
The increase in distance is explained by the Big Bang theory or great expansion.
There is also astronomical evidence:
* The redshift of the hydrogen spectral lines that is explained by the Dopler effect, which is a move away from objects
* Background radiation in the microwave range that comes from everywhere and would be the residue of a large initial explosion.

A bowling lane is 18 meters long. How long would it take a 1.5 m/s bowling ball to
roll down that lane?
16.5 seconds
16.5 meters
12 seconds
27 seconds
27 meters
12 meters
Divide distance by speed:
18 meters / 1.5 meters/ second = 12 seconds
Answer: 12 seconds
A bowling lane is 18 meters long. it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane, therefore the correct answer is the third option
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
The mathematical expression for velocity is given by
velocity= total displacement/Total time
As given in the problem a bowling lane is 18 meters long and the ball is moving with a velocity of 1.5 m/s in the roll-down lane we have to find the time period for the bowling ball to roll down that lane
Total displacement = 18 meters
the velocity of the ball = 1.5 m/s
time =?
By substituting the values in the formula of the velocity
1.5 = 18/t
t= 12 seconds
Thus , it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane
