Answer:
use formula: a= Vf-Vi/t

rearrange: Vf=at

solve: Vf= 4.0m/s squared x 6s

Vf = 24 m/s --> sigdigs

Vf = 2.4 x 10^1 m/s

rearrange: Vf=at

solve: Vf= 4.0m/s squared x 6s

Vf = 24 m/s --> sigdigs

Vf = 2.4 x 10^1 m/s

We observe that the ball hangs at an angle of θ=18.0o from the vertical. what is the magnitude of the electric field.

120 degrees Fahrenheit is how many degrees Kelvin?

Which type of weather event is caused by a tropical low-pressure system with strong, sustained winds?

Melody is riding her mountain bike along a trail with multiple hills. At the bottom of the second hill, she has 3200 J of kinetic energy. At the top of the third hill, when she is going the slowest, her potential energy measures 1650 J. Which statement below is true? A. The total amount of energy at the bottom of the hill cannot equal the amount at the top, because some of the energy from the environment is gained. B. The total amount of energy at the top is equal to the amount at the bottowm, but she gained some energy as she traveled due to a higher speed going down the first two hills. C. The total amount of energy at the bottom of the hill cannot be equal to the amount at the top, because some of the energy is lost.

For the elements with the electron affinities given in the table in the introduction, which element is most likely to accept an electron?

An indicator of average kinetic energy is temperature. Temperature is directly proportional to Kinetic energy of the molecules of an element.

**Answer:**

Temperature

**Explanation:**

The energy contained by a body due its motion is known as kinetic energy.From kinetic theory of gases, the average kinetic energy is proportional to temperature. More the temperature, more would be the speed of the particles. Gases having same temperature would have same average kinetic energy.

Thus, an indicator of average kinetic energy is **temperature.**

**Answer and explanation;**

-The diagram at the left represents the Sun (or any other one-solar-mass star) as a hydrogen-burning main-sequence star, with spectral type G and one solar luminosity. The next diagram shows the Sun after it has exhausted its core hydrogen and left the main sequence, making it a sub-giant with energy generated by hydrogen burning in a shell around an inert helium core.

-The third diagram shows the Sun a little later; its energy source is still hydrogen shell burning, but at this point it has expanded in size so much that it is a red giant. The final diagram (far right) shows the white dwarf corpse of a one-solar-mass star; it is hot because it is the exposed core of the dead star, but dim because it is small in size.

The right answer for the question that is being asked and shown above is that: "1-4-3-2." (main sequence-->red giant-->supergiant-->white dwarf). Assume that all four H-R diagrams below represent a star in different stages of its life, after it starts to fuse hydrogen in its core.

1 watt = 1 joule per second

(4 joules/second) x (3600 second/hour) x (8 hour)

= (4 x 3600 x 8) (joule)

To Build The Motor, Faraday Studied Electricity And Magnetism. Hope This helps!

For Invention of "Motor" and "Generator", Micheal Faraday did explore electricity and magnetism, he postulated his three laws of "Electromagnetic Induction" and two laws of "Electro-chemistry".

**In short, Option D) Electricity and Magnetism would be your answer.**

**Answer:**

the work done on the car by the applied force is **75 J.**

**Explanation:**

Given;

initial velocity of the car, v = 4 m/s

applied force in opposite direction, F = 5N

initial position of the car, x₀ = 5 m

final position of the car, x₁ = 20 m

displacement of the car, Δx = x₁ - x₀ = 20 m - 5m

= 15 m

The work done on the car by the applied force is calculated as follows;

W = F.Δx

W = 5 x 15

W = 75 J

Therefore, the work done on the car by the applied force is **75 J.**
