A family took a trip in a car traveling East from Greensboro to Wilmington, NC. Use the Graph to answer the questions below.

1: Calculate the average speed of the trip.

2: What was the average velocity of the car?

Note: Please don't put weird stuff or completely off-topic stuff, I really need help for this homework! Thanks!

Answer:

                       Freezing Water         Boiling Water

Centigrade             0                               100

Fahrenheit             32                               212

Kelvin                    273                              373

One needs to know these values for an understanding of the temperature scale

  9/5 C + 32 = F           Check for boiling points

 5/9 (F - 32) = C

Example:

  F = 9/5 C + 32 = 9/5 * 20 + 32 = 68 F

And deg K = C + 273

So 20 deg C = 293 deg K

Answer:

68 F and 293.16 K

Explanation:

T F= 1.8(20) + 32 = 68 F

TK= 20 +273.16 = 293.16 K

Answer:

gravity

Explanation:

its hard to explain its one of the resons we do gravity assists for space probes and such the meteor will catch earths gravity and be pulled in by it if you look at sednas orbit as it gets closer to the sun it speeds up.

The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.

Gravity is defined as the force by which a planet attracts another body towards its center.

Here,

The meteor was moving through space and the speed of the meteor started increasing as it moves closer to the earth.

This is because of the gravitational force of earth that is being exerted on the meteor. Gravitational force of earth is defined as the force of attraction that the earth exerts on another body in its gravitational field and draws them towards the center of the earth.

As the meteor moves towards the earth's , it gets accelerated by the earth's gravitational field such that the speed of the meteor increases and thus it attains more kinetic energy. As a result, the meteor moves faster when it gets closer to earth. This is because of the force of gravity of the earth.

Hence,

The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.

Explanation:

Retrograde motion in astronomy is, in general, orbital or rotational motion of an object in the direction opposite the rotation of its primary, that is, the central object (right figure). It may also describe other motions such as precession or nutation of an object's rotational axis. Prograde or direct motion is more normal motion in the same direction as the primary rotates. However, "retrograde" and "prograde" can also refer to an object other than the primary if so described. The direction of rotation is determined by an inertial frame of reference, such as distant fixed stars.

Retrograde motion occurs when a planet far from another planet and from which it is seen rotates at lower speed, creating the impression that it is "retrograding" with respect to the other planet.

Early astronomers get confused as they viewed the motion in the sky because they tried to explain it in terms of the geocentric theory.

Let suppose that we have a planetary system formed by a star and two planets rotating uniformly around the star. Besides, we assume that both planets are rotating at different velocities, and that planet A is more far away from the star than planet B, then the velocity of the planet A relative to planet B is:

[tex]\vec v_{A/B} = \vec {v}_{A}- \vec {v}_{B}[/tex] (1)

A retrograde motion of planet A occurs when [tex]\|\vec v_{A/B}\|\ne 0[/tex] and if [tex]\|\vec v_{A}\| < \|v_{B}\|[/tex] at least. In other words, retrograde motion exists when speed of planet A is less than speed of planet B, creating the impression that planet A is "retrograding" with respect to planet B.  This question is easy to solve and to explain by considering the star as an inertial framework, base of the heliocentrical model.

Early astronomers were confused and unable to explain the phenomenon due to their adherence to geocentrical model, which assumed the Earth was the center of the solar system.

Answer:

[tex]40.34\ \text{m}[/tex]

Explanation:

[tex]L_1[/tex] = Length of wire = 65 m

[tex]I_1[/tex] = Initial current = 1.8 A

[tex]I_2[/tex] = Final current = 2.9 A

We know

[tex]R\propto \dfrac{1}{I}[/tex]

and

[tex]R\propto L[/tex]

[tex]\dfrac{V}{I}\propto L\\\Rightarrow L\propto \dfrac{1}{I}[/tex]

so

[tex]\dfrac{L_2}{L_1}=\dfrac{I_1}{I_2}\\\Rightarrow L_2=\dfrac{I_1}{I_2}L_1\\\Rightarrow L_2=\dfrac{1.8}{2.9}\times 65\\\Rightarrow L_2=40.34\ \text{m}[/tex]

The length of the wire remaining on the spool is [tex]40.34\ \text{m}[/tex].

Answer:

You can do the reverse unit conversion from cm/s to m/s, or enter any two units below: Metre per second (U.S. spelling: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.

How does the weight of the nose on a paper

airplane affect the distance it will travel

when measured in centimeters?

EXPERIMENT CONCLUSION: (Explain whether or

not your data supports, or fails to support your identified

prediction. Explain why, including facts and details!)

The distance did increase when I added 1 paper clip.

However, I was surprised that the distance decreased

when I added a second paper clip. I believe this

happened because the nose of the plane became too

heavy. When the plane was released, the nose of the

plane descended much quicker. I think the plane was

more balanced in weight when only 1 clip was on the

nose.

Answer:

The speed of the riders on the Singapore Flyer is approximately 0.262 m/s

Explanation:

The dimensions of the tallest Ferris wheel in the world are;

The diameter of the Ferris wheel, D = 150 m

The tine it takes the Ferris wheel to make a full circle, T = 30 minutes = 30 min × 60 s/min = 1,800 seconds

The angular velocity of the Ferris wheel, ω = 2·π/T

The linear velocity of the Ferris wheel, v = r·ω = The speed of the riders

Where;

r = The radius of the Ferris wheel = D/2

D = 150 m

∴ r = 150 m/2 = 75 m

∴ v = r·2·π/T

∴ v = 75 m × 2 × π/(1,800 s) ≈ 0.262 m/s

The speed of the riders on the Singapore Flyer, v ≈ 0.262 m/s

Answer:

A.spontaneous generation

Answer:

W = 76 N

Explanation:

In this exercise you are asked to find the weight of the body.

Mass is a quantity that is invariant, it measures the same everywhere, the weight depends on where it is measured, a simple way to find the weight of a body is

          W = g m

where g is the constant of the place, in this case we have the weight of the body on Mars and its mass which is constant on Earth and on Mars

            W = 3.8 20

            W = 76 N

5) the law of energy conservation states that energy is neither created nor destroyed, therefore what happens is that you use energy and transform it into another type of energy,

Explanation:

4) This exercise is asked to give some examples of thermal and electrical energy transfer

the transfer of thermal energy occurs when we grasp a hot or cold body due to the difference in temperature between the body and us there is an exchange of heat, for example when drinking a cup of hot coffee there is a transfer of energy from the cup to the hand .

If we take a can of cold soda there is a transfer from hand to can.

Electrical transfer occurs, for example, when a current passes through a light bulb, it becomes incandescent and gives light.

In all modern electrical appliances there is transformation of electrical energy

5) the law of energy conservation states that energy is neither created nor destroyed, therefore what happens is that you use energy and transform it into another type of energy,

For example, when you lift a box, the potential energy of the box increases with height, but the energy of the person decreases because it does work that is negative.

In amusement park rides, the energy accumulated in one part of the game generally with height is transformed into energy of movement in another part of the game, but the total energy remains constant.
