<span>If the length of the racetrack measures 36 inches and is set at heights of 8 inches, 16 inches, and 24 inches, with the toy car rolling down in times of 7.8 seconds, 7.3 seconds, and 6.6 seconds respectively, this indicates that the height of the racetrack influences the speed of the toy car. The increase in height results in a quicker descent due to the effect of gravity on velocity, which describes the rate of motion. This scenario illustrates motion as a concept representing movement or a position change given certain circumstances over time.</span>

As the height of a sloped racetrack is raised, the velocity of a toy car moving on the track will also increase due to greater acceleration.

Sketch a position-time graph for a bear starting
Sav [3153]
Hopefully this clarifies things. The position remains unchanged over the span of 5 seconds, which indicates that it is at rest while time continues to pass. When the slope turns negative, it illustrates that the bear is moving backward, thus changing its direction.

The electric field in a particular space is = (x + 3.6) N/C with x in meters. Consider a cylindrical Gaussian surface of radius
Maru [3345]

Answer:

a) Ф = 0.016 N / C m, b) q_{int} = 0.14 10⁻¹² C

Explanation:

a) For this scenario, we rely on Gauss's law

          Ф = E.ds = q_{int} /ε₀

As the field points in the x direction, there is no flux through the cylinder walls.

          Ф = E A

         

The area of a circle is

           A = π r

          Ф = E π r

          Ф = (x- 3.6) r

Now, let's compute

          Ф = (3.7 -3.6) 0.16

          Ф = 0.016 N / C m

     

b) Using Gauss's law, we have

             q_{int} = Ф ε₀

 

Where the flow is present on both sides, at the face corresponding to x = 0, the flow is zero

             q_{int} = 0.016 8.85 10⁻¹²

             q_{int} = 0.14 10⁻¹² C
