Hi,

The goal of a theory is to explain natural and physical phenomena.

Hope it helps you...

Pls mark brainliest if it helps you...

(Answered by Benjemin)

We can define theory as:

"A logical-deductive or inductive and organized set of ideas that explain a given phenomenon, where the deductions are based on observations".

With this, we can see that the correct option is "To explain natural and physical phenomena"

Now let's explain this a little bit more.

Here we want to see the goal of a theory.

So, what is the end of a theory?

A theory wants to explain something. Someone sees a phenomenon, and in a need to understand it, uses the information that he/she has to try to explain it. Then he/she proceeds to do experiments to test if the theory is correct.

Concluding, the correct option is:

"To explain natural and physical phenomena"

Answer:

C

Explanation:

Options A and B are not even pointing in the direction as the vectors in the question so they shouldn't even be considered.

Option C looks like the closes since vectors A and B are pointing in a similar direction (negative x-axis)

The best representation for the resultant vector representing the resultant R=A+B would be option C because the result is represented by the closing side of the triangle, therefore the correct answer would be C.

The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.

Examples of vector quantities are displacement, velocity acceleration, force, etc.

As given in the problem we have to find out the resultant vector from the sum of vector A and vector B,

The resultant of the vector can be calculated with the help of the triangle law of the vector addition in which the sum is given by the closing side of the triangle.

Thus, the correct answer is option C.

When a car is traveling north, its acceleration vector can point south when it is slowing down.

A vector quantity has both magnitude and direction. The direction of a vector is always shown by the direction to which the arrow points.

If the car is travelling north, the direction of the acceleration vector will continue to point northwards.

However, when the car slows down, the direction of the accelerating vector will now point southwards.

The work-energy theorem explains the idea that the net work - the total work done by all the forces combined - done on an object is equal to the change in the kinetic energy of the object. After the net force is removed (no more work is being done) the object's total energy is altered as a result of the work that was done.

This idea is expressed in the following equation:

is the total work done

is the change in kinetic energy

is the final kinetic energy

is the initial kinetic energy

Explanation:

By the statement, Efficiency of a machine is 60% it is meant that 'The work output is 60% of the work input'. If you apply 100J of energy for a machine, it will be able to life load of 60 J only

A law is created using a theory

The correct answer is B.

Theories are constructed after there is numerous data collected during the experiment.

Theory construction is simply a process of formulating and bringing together different components of theories into a single form that is more meaningful.

These theories are usually supported by evidence (data) gathered from many experiments.

In addition, these theories may answer the basic questions of our universe such as;

Explanation:

The explanation here is a little differe because we are starting from rest. So, everyone does physics a little differently, but what I would start with is trying to find the accelaration. I've given the formula, now you are able to plug this into the displacement formula where you Velocity Initial = 0m/s (Since you are starting from rest) and V final = 6.00 m/s...

You just plug numbers into the formula after solving for accelaration and do some simple algebra! I hope this helps! I am attaching a new pdf for visuals! If you can't open it let me know! Also there is a star by accelaration because I didn't know if I spelled it right, sorry!

Density = 1 g/cm³ ...... 1000 Kg/ m³

acceleration due to gravity = 10 m/s²

Height = 50 cm......0.5 m

after collecting the data, use the formula to solve

pressure = pgh

= 1000 × 10 × 0.5

= 5000 Pa

Answer:

0.1 mm

Explanation:

Given data :  A stack of paper contains 500 sheets of paper.

The stack has dimensions of 0.297 m x 21.0 cm x

50.0 mm.

To Find : What is the thickness of one sheet of paper

So,

1 m = 1000 mm

1 m = 100 cm

1 cm =  10 mm

The stack has dimensions of 0.297 m x 21.0 cm x 50.0 mm.

0.297 m = 297 mm

21 cm = 210 m

297 mm * 210 mm are paper length width

Hence 50 mm is thickness of 500 sheets

-  thickness of one sheet of paper = 50/500  = 1/10 mm

= 0.1 mm

Hope It Helps :)

The thickness of one sheet of paper would be 62.37 ×10⁻⁶ meters.

The volume of the stack of paper in cm³ would be  0.031185 mm³.

Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis.

As given in the problem a stack of paper contains 500 sheets of paper. The stack has dimensions of 0.297 m x 21.0 cm x 50.0 mm.

The volume of the stack  =  0.297 m x 21.0 cm x 50.0 mm

                                          = 0.000297 mm×2.1 mm x 50.0 mm

the thickness of one sheet of paper = 0.000297 mm×2.1 mm x 50.0/500mm

                                                           =62.37 ×10⁻⁶ meters

The volume of the stack of paper = 31.185 cm³
