An airplane is trying to land on the runway using the path below. Vectors and Scalars Questions – NAT 5 What is the total distance traveled by the airplane? m What was the magnitude of the airplane's displacement? m What was the direction of the airplane's displacement? Please abbreviate
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.
Christina drives his moped 7 kilometers North. She stops for lunch and then drives 5 kilometers East. What distance did she cover? Please include the number and unit. 8.6 km What was the magnitude of her displacement? Please include the number and unit. What was the direction of her displacement? Please abbrieviate (N, S, E, W, etc.)
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.
A swimmer swims a half lap, moving from the left end to the right end of a pool that is 50 meters long. What is the Distance and Displacement?
Distance = 50m
Displacement = 50m to the right
Explanation: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
Answer:
The distance is 50m and the displacement is also 50 m
Explanation:
the swimmer traveled 50m =distance
the swimmer was now 50m away from the start=displacement
Assuming that the hill on the left will provide all of the potential energy for the ride, would this roller coaster actually make it around the loop?
Thanks!
No, this roller-coaster would not able to make it around the loop because the hill would need to be higher than the loop's highest part,
The potential energy stored in the roller coaster from the first hill is not sufficient to make around-the-loop.
What is mechanical energy?The sum of all the energy in motion (total kinetic energy) and all the energy that is stored in the system (total potential energy) is known as mechanical energy.
The expression for total mechanical energy can be given as follows
ME= PE + KE
The roller coaster would not be able to complete the loop because the hill would need to be higher than the highest point of the loop, and the potential energy stored in the roller coaster from the first hill would not be enough to complete the circle.
Therefore, the correct answer is option A.

finoccientific method
Answer: No.
Explanation:
A scientific theory is an explanation of some aspect of the natural world that can be tested several times, and follows the scientific method. And, when possible, theories are tested with experiments.
Now, a scientific theory must meet some criteria, and one of those is that it must be supported by several (and independent) strands of evidence.

What can make an engine stop working?Engines generally stop suddenly if they suffer from a lack of fuel or sparks. An engine that can stop dead without prior warning and has probably had an instant ignition failure although when it locks solid it's more probably to have seized.
There are two ways to stop a diesel engine, remove the fuel pump fuse or cut off the fuel or the air. The easy way to stop a boat engine is to cut off the air.
The most general reasons for poor engine combustion because of broken valve seals, overused piston rings, holes within cylinders, and forcing air to leak out.
Assuming it's a gasoline-powered vehicle when removing a fuse or breaker for the ignition or fuel injection, the car wouldn't start. An engine can be disabled by cutting off the fuel pump fuse or relay if equipped.

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

Must be 8 letters (Dimensional Analysis escape room)
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:
A-B-C-E-G-K-H-I
If multiple measurements are taken and they vary quite a bit from each other, the measurements are
Answer:
precise
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.

A cannonball is fired horizontally at the same time a ball being dropped from the same height How do the times it takes them to hit the ground compare?
Answer:
The cannonball and the ball will both take the same amount of time before they hit the ground.
Explanation:
For a ball fired horizontally from a given height, there is only a vertical acceleration on it towards the ground. This acceleration is equal to the acceleration due to gravity (g = 9.81 m/s^2). A ball dropped from a height will also only experience the same vertical acceleration downwards which is also equal to g = 9.81 m/s^2.
Therefore both the cannonball and the ball will take the same amount of time to hit the ground if they are released/fired from the same height.

If a car races around a 2.3 mile oval track 220 times, what is the displacement of the car in meters when it crosses the finish line.
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.
