Answer:
Between 2.0 s and 4.0 s (B and C)
Between 5.0 s and 8.0 s (D and E)
Between 10.0 s and 11.0 s (F and G)
Explanation:
The graph shown in the figure is a velocity-time graph, which means that:
- On the x-axis, the time is plotted
- On the y-axis, the velocity is plotted
Therefore, this means that the object is not moving when the line is horizontal (because at that moment, the velocity is constant, so the object is not moving). This occurs in the following intervals:
Between 2.0 s and 4.0 s (B and C)
Between 5.0 s and 8.0 s (D and E)
Between 10.0 s and 11.0 s (F and G)
From the graph, it would be possible to infer additional information. In particular:
- The area under the graph represents the total distance covered by the object
- The slope of the graph represents the acceleration of the object
The answer is supposed to be during the summer in Richmond,
the angle of the sun at noon from the vertical is 14 degrees which is equal to
Richmond's latitude of 37.5 degrees minus Earth's slope of 23.5 degrees. While in the winter, the angle of the sun at
noon from the vertical is 61 degrees.
Answer:
The equilibrium points include
x₁ = - 1.177
x₂ = 0
x₃ = 1.177
Explanation:
At equilibrium, the sum of forces acting on a body is equal to zero.
F(x) = ax (b − cx²) [a = 8.97, b = 7.83, c = 5.65]
F(x) = (abx - acx³)
= (8.97×7.83)x - (8.97×5.65)x³
F(x) = 70.2351x - 50.6805x³
At equilibrium, F(x) = 0
70.2351x - 50.6805x³ = 0
x(70.2351 - 50.6805x²) = 0
x = 0 or (70.2351 - 50.6805x²) = 0
70.2351 - 50.6805x² = 0
50.6805x² = 70.2351
x² = (70.2351/50.6805)
x² = 1.385840708
x = ± 1.177
So, x = -1.177, 0 and 1.177
x₁ = - 1.177
x₂ = 0
x₃ = 1.177
