The correct answer is [tex]1.5 m/ s^{2}[/tex]

Explanation:

In general terms, the acceleration refers to how velocity changes or increases. This is measured in meters per second squared ([tex]m/s^{2}[/tex]) or similar units such as kilometers per hour squared ([tex]km/h^{2}[/tex]). Moreover, to calculate acceleration it is necessary to subtract the initial velocity from the final velocity and then divide this into the time. The formula and operation are shown below:

[tex]a (acceleration) = \frac{v (final velocity) - u (initial velocity)}{t (time)}[/tex]

[tex]a= \frac{18 m/s - 0 m/s}{12 s}[/tex]    (Initial velocity is 0 m/s because the car was at rest)

[tex]a = \frac{18 m/s}{ 12 s}[/tex]

[tex]a = 1.5 m/s^{2}[/tex]

According to this, the acceleration of the car was [tex]1.5 m/s^{2}[/tex]

Answer:

Explanation:

efficiency = energy output x 100  / energy input

putting the values

22.3 = 6.25 x 10⁴ x 100 / energy input

energy input = .28 x 10⁶

= 28 x 10⁴ J  

energy that needs to be put into the engine = 28 x 10⁴

Answer:

The resistance of the clock circuit.

Explanation:

In electricity, the potential difference or voltage is the drive force. It is known as the electromotive force in a battery or generator. The potential difference is the difference in the higher terminal and the lower terminal of the circuit. The potential difference forces electrons to move in an orderly fashion, from the higher potential to the lower potential; this flowing electrons is what is called the current of the circuit. When the electrons flow, they meet a certain amount of resistance. This resistance is unique to the material of the circuitry, and does not change in a circuit. The value of the resistance of the circuit remains the same, even when the potential difference of the electrical energy source is depleted, and current stops to flow.

Answer:

8.0 x 10⁻³

Explanation:

(8.0×10⁻³)  - (2.5×10⁻⁵)

= (8.0×10⁻³)  - (2.5 × 10⁻² x 10⁻³)   (factor out 10⁻³)

= 10⁻³  [ 8 - (2.5 x 10⁻²) ]

= 10⁻³  [ 8 - 0.025 ]

= 10⁻³  [ 7.975 ]

= 7.975 x 10⁻³

however we can observe that both original numbers are expressed to 2 significant figures, hence we must express our answer also in 2 significant figures by rounding 7.975 to 8.0, thereby giving us:

8.0 x 10⁻³

Answer:

1.)When you arrive from school and you smell cookies baking in the kitchen your brain will tell you that you are hungry and that you should go to the kitchen at that point your sense organs like your nose helps you to detect that something is baking(cookies)and your nervous system (brain)will tell you that you are hungry and it will command/direct your brain to go to the kitchen then for you to eat the cookies and drink the milk the digestive system is going go help you to chew,swallow and digest the food which has been taken and when you also run to the kitchen at the beginning your brain will direct your skeletal and muscular system because the skeletons and muscles work hand in hand,and when you finish your meal the body will circulate some nutrients or minerals from the food or snack taken to other parts of the body for energy.

2.)When you sleep the whole body is asleep except the heart which needs to continue circulating blood around the whole system and sometimes the brain may not rest when you are sleeping it may continue to do it's work that's why some people usually sleep walk or sleep talk,it means the brain is not at rest and still doing some things....Thank you for the question I hope it is very useful to you.

Answer:

trailers

Explanation:

Some vehicles, like trailers, have different rules for registration and renewal

Before registering a trailer, you will generally need to submit a signed title to verify your ownership. Alternately, you might be able to use a manufacturer’s statement of origin.

You will also need to sign and submit an application for the license and title of the trailer, along with receipts of applicable property taxes. Finally, you will need to pay the registration fees.

Before you make a trip to the DMV, make sure to have two forms of photo ID on hand to verify your identity when you speak with an agent. For example, your driver’s license might serve as the primary form of ID, and a passport could serve as the second.

If you do not have a passport, you could use a military identification card instead. If your only form of photo ID is your driver’s license, be sure to have other forms of identification on hand, such as your birth certificate and the card with your Social Security number.

Hence Some vehicles, like trailers, have different rules for registration and renewal.

Explanation:

Given :

Steve walks from his house 5 km South then turns east and walks 2 km. Then he walks 9 km North to his older sister's house. She gives him a ride to his friend Fred's house 2 km West.

To Find :

The total distance covered by Steve .

Solution :

We know , distance is the actual measurement space between two points .

Now , total distance travelled by Steve is the sum of all distance travelled .

[tex]T=5+2+9+2\\\\T=18\ km[/tex]

So , total distance covered by Steve is 18 km .

Hence , this is the required solution .

The distance Steve traveled is mathematically given as

T=18Km

Question Parameters:

Steve walks from his house 5 km South then turns east and walks 2 km.

Then he walks 9 km North to his older sister's house.

Generally, the total distance has Steve traveled is mathematically given as

T=5+2+9+2

T=18Km

In conclusion, because the distance is the measure of space b/w two points the total distance traveled is

T=18Km

Answer:

  d = 845 m

Explanation:

This is an exercise in kinematics, specifically accelerated motion, let's use the equation

         v² = v₀² + 2 a d

since airplanes start from rest their initial velocity is zero

         v² = 2ad

         d = v2 / 2a

let's calculate

         d = 65² / (2 2.5)

         d = 845 m

this is the minimum distance from the track

Answer:

m = T/10 = (1/10) T

Explanation:

From the question given:

∑F = ma .... (1)

∑F = T – 10m .... (2)

a = 0 m/s²

m =?

Thus, we can obtain m in terms of T as shown below:

From equation (1)

∑F = ma

a = 0 m/s²

∑F = ma = m × 0

∑F = 0

Next, substitute the value of ∑F into equation (2) to obtain m. This is illustrated below:

∑F = T – 10m

∑F = 0

0 = T – 10m

Rearrange

0 + 10m = T

10m = T

Divide both side by 10

m = T/10

m = (1/10) T

Therefore, m is (1/10) T

Answer:

It depends on the amount of pressure needed to cut your material.  Metal is a tougher material to cut though, so the blades must be shorter to create more pressure to break through the metal.  Cloth on the other hand is easier to cut through so the blades can be longer in order to cut more in each snip.
