Color, Opacity, Hardness

The three properties that can be observed in a substance will be density, physical state, and color.

A kind of matter with predictable chemical composition and physical characteristics is referred to as a chemical substance. According to certain texts, a chemical compound cannot be physically divided into its component parts without rupturing chemical bonds.

A substance's physical property is a quality that can be seen or quantified without affecting the substance's identity. Color, density, hardness, and boiling and melting points are examples of physical qualities. The capacity of a material to go through a certain chemical transition is described by its chemical property.

Explanation:

Given:

Δy = 0 m

v₀ = 20 m/s

a = -10 m/s²

Find: t

Δy = v₀ t + ½ at²

0 m = (20 m/s) t + ½ (-10 m/s²) t²

0 = 20t − 5t²

Answer:

acceleration of the car is 3 m\s^2

Explanation:

from rest means the initial velocity (vi) is zero

time = 5s

final velocity (vf) = 15m\s

a = vf - vi \ t

a = (15-0) \ 5

a= 3 m\s^2

which means that the car is speeding up 3 meters every second

Answer:

3m/s

Simple

Explanation:

Solution,

U=0

Velocity=15m/s

Time=5 sec

Now,

Acceleration=V-U÷T

=15m/s-0÷5

=15m/s÷5

=3m/s

Hence, the acceleratiob of the car is 3m/s.

The time period of a simple pendulum is given by :

[tex]T=2\pi \sqrt{\dfrac{L}{g}}[/tex]

L is length of the pendulum and g is acceleration due to gravity

It is very much clear that the time period depends on the length of the pendulum.

In this problem, there are 100 simple pendulums in a room having identical bobs which are displaced to different extents but only 25 of these pendulums have different time periods. The only reason for 25 pendulums having different time periods is that they have different lengths than the other 75 pendulums.

Answer:

18.9 N or 19 N rounded

Explanation:

m = 0.145 kg

a = 130 m/s^2

F = ma = (0.145 kg)(130 m/s^2) = 18.9 N

Magnitude of the average force

F = 18. 9 N

There are three laws of motion that are  given by  Newton in order to study the Force and Inertia on the objects in motion or rest.

Newton's First Law defines Inertia

The second law gives the definition of Force

Third law states about action reaction pairs on the objects interacting with each other.

According to Newton' s second law of motion we can write equation (1)

[tex]\rm F = ma.....(1) \\\rm Where\; F = Net\; unbalanced\; external\; force\; acting\; on \; the \; system \\\\a = acceleration \; of \; center\; of\; mass\\[/tex]

Now according to the question

we can write

Mass of the baseball = 0.145 kg

Acceleration of the baseball = 130 [tex]m/s^2[/tex]

Magnitude of the average force can be find out by putting in equation (1)

F = ( 0.145 ) ( 130) = 18.85 N [tex]\approx[/tex] 18. 9 N

Explanation:

Answer:

A.) 4.81 seconds

B.) 44.6 m/s

Explanation:

He begins his dive by jumping up with a velocity of 5 (m/s).

Let us first calculate the maximum height reached by using third equation of motion

V^2 = U^2 - 2gH

At maximum height, V = 0

0 = 5^5 - 2 × 9.8H

19.6H = 25

H = 25 /19.6

H = 1.28 m

The time taken for the diver to reach the water from the maximum height can be calculated by using second equation of motion.

Where height h = 1.28 + 100 = 101.28 m

h = Ut + 1/2gt^2

As the diver drop from maximum height, U = 0

101.28 = 1/2 × 9.8 × t^2

4.9t^2 = 101.28

t^2 = 101.28/4.9

t^2 = 20.669

t = sqrt ( 20.669)

t = 4.55s

As the diver jumped up, the time taken to reach the maximum height will be

Time = 1.28 / 5 = 0.256

The time taken for him to hit the water below will be 0.256 + 4.55 = 4.81 seconds

B.) Velocity right before he hits the water will be

V^2 = U^2 + 2gH

But U = 0

V^2 = 2 × 9.8 × 101.28

V^2 = 1985.09

V = 44.6 m/s

A.) The time taken should be 4.81 seconds

B.) The velocity should be 44.6 m/s

Here we used third equation of motion

V^2 = U^2 - 2gH

At maximum height, V = 0

Now

0 = 5^5 - 2 × 9.8H

19.6H = 25

H = 25 /19.6

H = 1.28 m

Here the second equation of motion.

Here height h = 1.28 + 100 = 101.28 m

So,

h = Ut + 1/2gt^2

Since the diver drop from maximum height, U = 0

So,

101.28 = 1/2 × 9.8 × t^2

4.9t^2 = 101.28

t^2 = 101.28/4.9

t^2 = 20.669

t = sqrt ( 20.669)

t = 4.55s

Now

Time = 1.28 / 5 = 0.256

Finally the time should be

=  0.256 + 4.55

= 4.81 seconds

B.)

We know that

V^2 = U^2 + 2gH

But U = 0

So,

V^2 = 2 × 9.8 × 101.28

V^2 = 1985.09

V = 44.6 m/s

Answer: distance = 75ft

displacement = 35ft east

The required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.

To solve this problem, we first need to understand the difference between distance and displacement.

Distance is the total length traveled by an object, regardless of its starting and ending points. In this case, the distance traveled by Maria would be the sum of the distances of each segment of her journey,
Distance = 20 ft + 35 ft + 20 ft = 75 ft

Displacement, on the other hand, is the straight-line distance from the starting point to the ending point, measured in a straight line.

So let's assume the movement of maria on  coordinate where North and East are positive movements and West and south are negative now add the distances,

Displacement =20 + 35 - 20 = 35 ft

Thus, the required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.

The advantages and disadvantages of converting our system of measurement in the united states from the English system to the international system of units

The difference between SI units and english system units.

SI systems,

The SI system uses metre, kilogram and second.

English system,

The english system uses yard, foot, cubit, mile, quart, pint, gallons, etc.

We need to find the comparison between  system of measurement in the united states from the English system to the international system of units

Advantage :

The most advantage of SI unit is that it has only one unit for each quantity. It means, it is never needed to change from one unit to another unit and here is no changing factors for students to memorize.

Disadvantage :

The most disadvantage of english system is that it has more unit for each quantity. It means, it is needed to change from one unit to another unit and here is changing factors most for students to memorize.

Hence, This is required answer.

Transitioning to the International System of Units (SI) offers global standardization, simplicity, and consistency in measurements, promoting scientific accuracy and ease of communication. However, the process involves costs, potential resistance to change, and considerations of cultural and practical factors that need to be carefully addressed for a successful conversion.

Here's a comparison:

Advantages of converting to the SI system:

1) Global Standardization: The SI system is the most widely used system of measurement worldwide, ensuring uniformity and ease of communication in international trade, science, and engineering.

2) Simplicity and Coherence: The SI system is based on a decimal system, making conversions between units straightforward and logical.

3) Consistency and Interchangeability: SI units are based on well-defined standards and physical constants, providing a consistent and unambiguous way to express quantities, and improving the accuracy and reliability of measurements.

4) Learning and Education: Adopting the SI system in education can simplify the learning process for students and facilitate the understanding of scientific concepts, promoting scientific literacy.

5) Compatibility with Technology: The SI system is compatible with modern technology and scientific instruments, enhancing the accuracy and precision of measurements.

Disadvantages of converting to the SI system:

1) Transition Costs: Implementing a change in the entire measurement system can be costly, requiring new standards, education, and recalibration of equipment and infrastructure.

2) Resistance to Change: People who are familiar with the English system may initially resist adopting the SI system, leading to a learning curve and potential confusion during the transition.

3) Cultural Factors: The English system has been ingrained in the culture and everyday life of the United States, and some may argue for preserving the historical tradition of the system.

4) Potential Loss of Precision: In some cases, the SI system may result in rounded or approximated measurements, leading to potential loss of precision compared to the English system.

5) Mixing Units: During the transition period, there might be a mix of both systems, leading to potential errors or misunderstandings when using different units.

In summary, transitioning to the International System of Units (SI) offers global standardization, simplicity, and consistency in measurements, promoting scientific accuracy and ease of communication.
