Explanation:

Which option is potentially environmental benefit of adopting a new technology?

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: It is c.

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:

A remote-controlled, pilot-operated _Relief__ valve is type of pilot-operated relief valve that uses one or more external pilot valves to set the pressure at which the relief valve will open.

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.

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.

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.

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.

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.

Answer:

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.

Explanation:

Answer:

Elements are made up of only one type of atom. Each element has a unique chemical symbol. Elements can be identified by their atomic number.

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

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

Answer:

injecting

Explanation:

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
