Answers

Answer 1

Answer:

2.5 seconds.

Explanation:

Time equals speed divided by acceleration. gravitational acceleration is equal to 9.8 [tex]\frac{m}{s^{2} }[/tex]. You know that the speed is equal to 24.5 m/s, so plug those values into the equation.

24.5 / 9.8 = 2.5 seconds.

Hope this helps!

Answer 2

Answer:  2.5 s

Time=speed/acceleration

Gravitational Acceleration=9.8 m/s^2

Answers

Answer:

This is required answer.

Explanation:

Given that,

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.

Explanation:

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.

Which of the following is most likely to happen when energy is transferred to an object A) the object will stay exactly the same B)The object Will begin to move C)the force on the object will decrease D) the mass of the object will increase

Answers

Answer:

B. the object will begin to move

Explanation:

If energy is transferred the object will definitely change so it CANNOT be "A". If you add energy the object will have more force so it CANNOT be "C". The mass of an object can't increase just by giving an object energy so it CANNOT be "D"

When energy is transferred to an object, the object is most likely to move either it gains a kinetic energy or it undergo a thermal vibration if thermal energy is applied.

What is energy transfer?

Energy can be transferred from its high energetic area to less . All forms of energy can be transferred like this.For example, heat energy can be transferred through various modes such as conduction, convection, radiation etc.

When an object gain some energy its particles starts to vibrate and move apart. This makes the intermolecular force of attraction between molecules weaker than before and they tend to be more reactive.

The energy transferred to an object does not make any change in mass, or any of its innate properties or does not apply any force. Therefore, option B is correct.

Answers

This means that the body is in rest, as the there is no change in displacement or distance (depending on which graph you are looking at), over time

The position- time graph of an object gives the velocity of the object. If the graph shows a horizontal line along the x axis, the object is stationary.

What is velocity?

Velocity of an object is a physical quantity measuring the distance covered per unit time. It is a vector quantity and thus have a magnitude and direction. Velocity is thus, the ratio of change in distance to the change in time.

v = dx/dt.

A moving object is always associated with certain velocity. Which can be constant or changing. The plot of position v/s time gives the change in position with respect to time. Thus, velocity can be calculated from this.

If the position -time graph shows a horizontal line means there is no change in distance with time and the velocity of the object is zero. Thus, the object is stationary or at rest.

As the earth rotates through one revolution, a person standing on the equator traces out a circular path whose radius is equal to the radius of the earth (6.38×10^6). What is the average speed of this person in meters per second? If we are standing in latitude 43° north what is our average speed?

Answers

Answer:

The average speed will be "1038 mph".

Explanation:

Period for one revolution is:

T = 24 hours

  = 86,400 sec

x = c = 2πr

The given values is:

r = 6.38×10⁶ m

Now,

⇒  [tex]T=\frac{2 \pi r}{v}[/tex]

Or,

⇒  [tex]v=\frac{2 \pi r}{T}[/tex]

On substituting the values, we get

       [tex]=\frac{2 \pi (6.38\times 10^6)}{86,400}[/tex]

       [tex]=464 \ min/sec[/tex]

       [tex]=(464 \frac{min}{sec}) (\frac{3600 \ sec}{1 \ hour} )(\frac{1 \ mi}{1609 \ m} )[/tex]

A horse is grazing for food. It trots rightward 15 m to eat a carrot, then walks rightward 20 m, to another carrot, then turns leftwards to walk 4m, to bite an apple. The horse walks a total time of 74 seconds. What is the magnitude of its average velocity?
(** HINT- you may want to draw this out, remember with VELOCITY direction matters-opposite vectors cancel out-with SPEED direction does not matter).

Answers

Answer:

0.42s

Explanation:

Velocity = Displacement/time

Displacement of the horse is the distance covered in a specified direction

Total distance of the horse towards the right = 15m + 20m = 35m

Total distance of the horse towards the left = 4m

Displacement = Distance towards the right - Distance towards the left

Displacement = 35m-4m

Displacement =  31m

Time taken = 74seconds

substitute the values gotten into the velocity formula

average velocity = 31m/74s

average velocity = 0.42m/s

Hence the magnitude of its average velocity is 0.42s

Which example best represents balanced forces? an elevator stopped on the third floor a basketball shot into a hoop a sled sliding down a snowy hill a tow truck pulling a car out of a ditch

Answers

Answer:

an elevator stopping on the third floor

Explanation:

The example that best represent balanced force as regards this question is an elevator stopped on the third floor.

Balanced force can be regarded as resultant force that has a magnitude of zero when acted on an object. When forces that are been subjected on a body are zero then the force is balanced.In the case of the elevator, immediately it stopped at a particular floor, then it will gave a balanced force, because at that point all forces acting on it becomes zeroWhen a car is pushed from a ditch , the force is acting from a side so its not balanced

Examples of balanced forces are;

The weight of object as well as normal force acting on it can be regarded as been balanced.When pushing a car at both opposite sides with the same forces.A lizard that hangs in vertical position.

Therefore option A is correct, because balanced force exist as the elevator stopped.

long does it take for him to hit the water below? b. What is his velocity right before he hits the water?

Answers

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

Calculation of the time taken and velocity:

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

A car, initially traveling 24.0ft/s, steadily speeds up to 58.0ft/s in 5.40s. Determine all unknowns and answer the following question.

How far did the car travel during this time?

Answers

Answer:

acceleration = 6.29 ft^2/s

distance traveled by car = 405 ft

Explanation:

formula 1 : u = v - (a*t)

where u = initial velocity

v = final velocity

a = acceleration

t = time.

solving for acceleration.

24 = 58 - (a*5.4)

a = (58 - 24)/ 5.4

a = 340/ 54 = 6.29 ft^2/s

formula 2: v = d/t - (a*t/2)

58 = d/5.4 - ((340*54)/20)

d = 405 ft
