describe the motion of an object has an acceleration of 0 m/s2

Answers

Answer:

The object is either traveling at a constant speed or is not moving.

Explanation:

It is not possible for the position of an object to be changing and the acceleration to be zero. Acceleration is the change in velocity divided by the change in time.

There are only two possible situations if the motion of an object has an acceleration of 0 m/s²,

Either the object is at rest or the object is moving at a uniform velocity

What is acceleration?

The rate of change of the velocity with respect to time is known as the acceleration of the object. Generally, the unit of acceleration is considered as meter/seconds².

As we know the rate of change of velocity is known as acceleration

acceleration =change in velocity/change in time

As given in the problem statement the motion of an object has an acceleration of 0 m/s²

Considering that every moving particle has zero overall acceleration. The particle will then experience zero overall applied force.

Newton's first law states that if all forces acting on a moving object are equal to zero, the object will be traveling in a straight line at a constant speed.

When there is no acceleration, the particle's motion will continue in the same direction. Additionally, the particle's velocity will not remain constant if the direction of motion changes.

Thus, If an object's motion has an acceleration of 0 m/s², there are only two possible outcomes: either the object is at rest or it is moving at a constant speed.

Write a explanation explaining why red is a beautiful color is not a hypothesis

Answers

Answer:

Please find the explanation below

Explanation:

A hypothesis in science is a testable explanation that is yet to be tested via experimentation. It is a predictive statement or suggested solution to an observation. A hypothesis aims at finding a possible explanation/answer to a question, which is subject to testing. One important aspect of formulating a hypothesis is that it tends to connect the independent variable with the dependent/measurable variable.

The statement "RED IS A BEAUTIFUL COLOR" cannot be considered a hypothesis because it does not aim to answer a question that can undergo experimental testing. This statement can not be measured via experimentation. The statement is not a possible answer to a question but rather a personal opinion about something.

If, as is typical, each of them breathes about 500 cm3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year

Answers

Answer:

a) 12614.4 m^3

b) 28.8 m

Explanation:

The complete question is

Four astronauts are in a spherical space station. (a) If, as is typical, each of them breathes about 500 cm^3 of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year? (b) What would the diameter (in meters) of the space station have to be to contain all this air?

The average breathing rate is 12 breaths per minute

there are 60 minutes x 24 hours x 365 days in a year = 525600 minutes in a year

if an average human takes 12 breath per minute, then in a year an average human take 12 x 525600 = 6307200 breath

For the four astronauts, the amount of breath = 4 x 6307200 = 25228800 breath in total.

The volume of air per breath = 500 cm^3

1 cm^3 = 10^-6 m^3

500 cm^3 = [tex]x[/tex] m^3

[tex]x[/tex] = 500 x 10^-6 = 5 x 10^-4 m^3

Therefore in a year, the volume of these astronauts breath in a year = 5 x 10^-4 x 25228800 = 12614.4 m^3

b) If the space station is spherical, the volume will be given as = [tex]\frac{4}{3} \pi r^3[/tex]

where r is the radius of the space station

This volume of the space station must be able to contain all the volume of breath produced by the astronauts which is = 12614.4 m^3

Equating, we have

12614.4 = [tex]\frac{4}{3} \pi r^3[/tex]

12614.4 = [tex]\frac{4}{3}*3.142*r^3[/tex]

12614.4 = 4.1893[tex]r^{3}[/tex]

[tex]r^{3}[/tex] = 12614.4/4.1893 = 3011.1

r = [tex]\sqrt[3]{3011.1}[/tex] = 14.4 m

diameter of the space station = 14.4 m x 2 =  28.8 m

Explanation:

usatestprep

The degree of agreement between two or more measurements is what is referred to as a substance's precision. Your measurement is incredibly exact, but not necessarily correct if you weigh the same substance five times and obtain 3.2 kg each time.

What precision vary quite a bit from each other?

The level of agreement between measurements of the same thing is known as precision. Accuracy is not necessary for precision. In other words, it is possible to be accurate without being exact, as well as to be highly precise but not particularly accurate.

As was mentioned before, you can be extremely exact but inaccurate. You can also be precise while being inaccurate. For instance, you have accuracy without precision if, on average, your measurements for a specific substance are close to the known value, but the measurements are far apart.

Therefore, The standard deviation, or the amount and frequency of measurement variation, is what determines precision. A high standard deviation indicates low precision, according to the metric.

Answers

Answer:

Dependent Variable: growth of claw size in mutant lobsters

Independent variable: different amounts of seawater contaminated with Pepsi

Controlled variable: Mutant Lobsters

Explanation:

A dependent variable is one that depends on another factor to get it's result.

An independent variable is one that doesn't rely on another factor/variable to derive it's result.

A controlled variable is one which is constant and remains unchanged throughout the course of the experiment/investigation. Which means it verifies the behavior between the dependent and independent variables.

Now, in the question, the growth of claw size in the mutant lobsters depends on the different amounts of seawater contaminated with Pepsi.

Thus growth of claw size in mutant lobsters is a dependent variable while different amounts of seawater contaminated with Pepsi is an independent variable.

The mutant lobsters would be used throughout the investigation to know the relationship between the dependent and independent variable and wouldn't be changed. Thus, they are controlled variable.

Neglecting air resistance, which of the following statements is true regarding an object in freefall?Lector inmersivo A. An object’s acceleration increases at a constant rate. B. An object maintains a constant velocity. C. An object falls an equal distance in between each second. D. An object’s velocity and acceleration both increase at a constant rate. E. An object’s velocity changes at a constant rate, and its acceleration remains constant.

Answers

Answer:

E. An object’s velocity changes at a constant rate, and its acceleration remains constant.

Explanation:

When an object is in freefall, it implies that the object is falling freely under gravity. If it falls towards the earth surface, the fall is in the direction of the Earth's gravitational force.

At the point of release of the object, its initial velocity is zero because it is at rest. But when released, its velocity increases at a constant rate until it is acted upon by an external force. But its acceleration remains constant, acceleration due to gravity.

Must be 8 letters (Dimensional Analysis escape room)

Answers

Answer: A-B-C-E-G-K-H-I

Explanation:

Ok, we start at A.

16 pints = x gallons.

We know that:

1 pint = 0.125 al

then:

16pint = 16*(0.125gal) = 2 gal.

The second letter is B.

Now we have:

12,320 yd = X mi

And we know that:

1 mi = 1760 yd.

Then 12,320yd = (12,320/1760) mi = 7mi

the letter is C.

Now we have:

432 cups = X gals

and:

1 cup = 0.0625 gal

then 432 cups = 432*(0.0625 gal) = 27 gal.

The next letter is E.

Now we have:

1/4 ton = X pounds.

And 1 ton = 2000 pounds

then 1/4 ton = (1/4)*2000 pounds = 500 pounds

The next letter is G.

Now we have:

3.5 gal = X ounces.

and we know that:

1 gal = 128 oz

Then:

3.5 gal = 3.5*(128oz) = 448oz

The next letter is K.

Now we have:

1/2 day = x minutes.

and we know that:

1 day = 24*60 min = 1440 min

then 1/2 day = (1/2)*1440 min = 720 min.

The next letter is H.

Now we have:

360 in = x yd

And we know that:

1yd = 36 inches.

then 360 in = (360/36) = 10 yd.

The next letter is I

Now we have:

56 cups = x quarts.

and we know that;

1cup = 0.25 quart

then: 56 cups = 56*0.25 quart = 14

So here this ends.

Then the code is:

Answers

Answer:

team A - team B = 450 N - 415 N

                                               = 35 N

Explanation:

net force on the rope is 35 N and the direction is towards A.since the two teams are pulling away from each other with the given forces, the net force can be calculated by subtracting the forces.

The net force on the rope is 35N in right direction

What is Net Force? The net force is the vector sum of forces acting on an object,How to calculate the Net force?The force applied by Team A is 450N to the right (Given)The force applied by Team B is 415 N to the left (Given)We need to find the Net force applied on the rope and the direction

As We know that ,

[tex]F_{net} = F_1+F_2[/tex]

Now as The direction of the Team A is right so the Force applied will be positive, that is 450N

Simultaneously , The direction of Team B is left so the Force applied will be negative , that is -415N

Here,

F1 = 450N

F2 = -415N

[tex]F_{net} = F_1+F_2[/tex]

= 450+ (-415N)

= 450-415

=35N

Hence the net force applied is 35N and as the net force is positive the direction will be right

A long distance runner sees the finish line and accelerates at a rate in 1.2 m/s2 for
the last 3 seconds to win the race. If he was initially running at speed of 3.2 m/s,
how far did he travel?

Answers

Answer: he did travel 15 meters.

Explanation:

We have the data:

Acceleration = a = 1.2 m/s^2

Time lapes = 3 seconds

Initial speed = 3.2 m/s.

Then we start writing the acceleration:

a(t) = 1.2 m/s^2

now for the velocity, we integrate over time:

v(t) = (1.2 m/s^2)*t + v0

with v0 = 3.2 m/s

v(t) = (1.2 m/s^2)*t + 3.2 m/s

For the position, we integrate again.

p(t) = (1/2)*(1.2 m/s^2)*t^2 + 3.2m/s*t + p0

Because we want to know the displacementin those 3 seconds ( p(3s) - p(0s)) we can use p0 = 0m

Then the displacement at t = 3s will be equal to p(3s).

p(3s) = (1/2)*(1.2 m/s^2)*(3s)^2 + 3.2m/s*3s = 15m
