C and D are both possible.
But we have no idea which one is correct based on the given illustration, because you didn't give the illustration.
Aswer:
False, the values of the distance traveled and the displacement only coincide when the trayectorie is a straight line. Otherwise, the distance will always be greater than the offset.
Although these terms are used synonymously in other cases, they are totally different. Since the distance that a mobile travels is the equivalent of the length of its trajectory. Whereas, the displacement will be a vector magnitude.

Answer:
Tension on each chain: 30.28N
Explanation:
We start by drawing a free-body diagram of all the forces acting on the flower pot. These are:
1) the weight of the flower pot which is the product of the pot's mass time the acceleration of gravity "g" (pictured in green and represented by in the diagram), and
2) the two tensions in the chains, which since they are symmetric, are of the same size, pictured in red color and represented by the letter "T" in the diagram.
We also decompose the tensions T in two components each (a vertical component V and a horizontal component h) which are pictured in blue.
All vertical forces must cancel out since the object is in static equilibrium, so:
The horizontal components h are equal, and since they act in opposite directions, they indeed cancel out.
Now to calculate the tension, we use the fact that we know the angle between T and the component V. They in fact are related via the cosine of the angle because they are the hypotenuse and the adjacent side in a right angle triangle:
Answer:
(a) The equivalent resistance is 18.06 Ω
(b) The current in each resistor is 0.665 A
Explanation:
Given;
first resistor, R₁ = 2.25 Ω
second resistor, R₂ = 5.90 Ω
third resistor, R₃ = 9.91 Ω
Equivalent resistance;
2.25 Ω + 5.90 Ω + 9.91 Ω
18.06 Ω
The current in each resistor;
For series connection, current is the same in every resistor.
V = I(R₁ + R₂ + R₃)
