Answer: 0 miles.

Explanation:

First let's define what the displacement is:

The displacement is defined as the difference between the final position and the initial position.

So, if for example, you start at your house, then go to a store, and then go back to your house, your total displacement will be zero, because the initial position and the final position are the same.

Then when the car reaches the final line, it will be in the same place that it started (because this is an oval track, so the finish line connects with the starting point)

Then the total displacement is 0miles.

Explanation:

The attached image shows the path followed by an airplane that is trying to land. From the figure, it can be seen that initially, its position was 200 m due east, then 150 m due south, 200 m due west, 250 m due south.

(a) The total path covered during its entire journey is called distance.

D = 200 m+150 m+200 m+250 m

D = 800 m

(b) The shortest path covered by an object is called displacement of an object. The shortest path covered is shown by red color. It means that displacement is (150+250) m = 400 m

(c) It is clear from the figure that, the Airplane's displacement is in the south direction.

Answer:

example 5foot 5in

a)65

b)165.1

c) 1.83

Explanation:

a) multiply the amount of feet by 12. thats 60. then add the extra 5 inches. 65 inches in total.

b) multiply your previous answer by 2.54. (there are 2.54 centimeters for every inch) the answer is 165.1

c) a yard is three feet. divide 5foot 5 by 3.

Answer:

Explanation:

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

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.

Answer:

She covers the distance is 12 km.

The magnitude of displacement is 8.6 km.

The direction of her displacement is north east.

Explanation:

Given that,

Christina drives his moped 7 kilometers North and stop for lunch and then drive 5 km east.

We need to calculate the total distance

Using formula of distance

[tex]d=d_{1}+d_{2}[/tex]

Put the value into the formula

[tex]d=7+5[/tex]

[tex]d=12\ km[/tex]

We need to calculate the magnitude of displacement

Using formula of displacement

[tex]D=xi+yj[/tex]

[tex]D=5i+7j[/tex]

[tex]D=\sqrt{5^2+7^2}[/tex]

[tex]D= 8.6\ km[/tex]

The direction of her displacement is north east.

Hence, She covers the distance is 12 km.

The magnitude of displacement is 8.6 km.

The direction of her displacement is north east.

Answer:

Explanation:

The question is incomplete. Here is the complete question.

You move at 3 m/s north, then at 5 m/s directly west. Find your displacement.

The displacement is the distance moved in a specified direction. If you first move 3m/s due to north, this means you moved in the positive y direction hence we can say that y = 3m/s. Then if you move 5m/s directly due west this means you moved in the negative x direction hence we can say that x = -5m/s. The displacement will be gotten using the pythagoras theorem as shown.

D² = x²+y²

D² = (-5)²+3²

D² = 25+9

D = √34 m/s

Hence your displacement is √34 m/s and the total distance covered is 3m/s + 5m/s = 8m/s

Answer:D

Explanation:

The characteristic shared by extrusions, intrusions, and faults is  all are younger than surrounding rocks.

The correct option is fourth.

Extrusion is a process of extruding.

Intrusion is the process of intruding. The forced entry of molten rock or magma into two different rock formations. It is also the intruded magma.

The movement of magma over the surface of the Earth coming out through volcano craters and cracking in the earth's crust forms igneous rock.

The characteristic shared by extrusions, intrusions, and faults is  all are younger than surrounding rocks.

The surrounding rocks are already present. After that the entry of magma occurs which forms new rock. So, in age surrounding rocks are older than the middle.

Thus, the correct option is fourth.

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.

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.

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

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.

Answer: 114.543 i think

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

Explanation:

Answer:

Yes

Explanation:

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:

Distance = 50m

Displacement = 50m to the right

Distance is the total length of a given path. It is a scalar quantity and thus takes no consideration on the direction of the path.

Displacement on the other hand is the change in position of an object. It is a vector quantity and takes consideration on the direction of the object.

From the question:

The swimmer swims half lap by moving from the left end to the right end of a pool that is 50m long.

Distance = total length of the given path = 50m

Displacement = change in position of the swimmer from the left end (0m) to the right end (50m) = 50 - 0 = 50m

Since direction is important in displacement, the complete details of the displacement should be 50m to the right
