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

Answer:

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.

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

Jennifer, who has a mass of 50.0 kg, is riding at 35.0 m/s in her red sports car when she must suddenly slam on the brakes to avoid hitting a deer crossing the road. She strikes the air bag, that brings her body to a stop in 0.500 s. What average force does the seat belt exert on her
Answer:
Average force = 3.5 kN
Explanation:
Given:
Mass of Jennifer (m) = 50 kg
Initial velocity = 35 m/s
Time taken to stop body = 0.5 s
Find:
Average force
Computation:
v = u + at
0 = 35 + a(0.5)
Acceleration (a) = - 70 m/s² = 70 m/s²
Average force = ma
Average force = (50(70)
Average force = 3500 N
Average force = 3.5 kN
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
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
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?
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

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.
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.
