Answer:
<em>The angle between vectors A and B is 116.6°.</em>
Explanation:
<u>Geometric Addition of Vectors</u>
The geometric construction of the situation stated in the question is shown in the image below.
The angle between vectors A and B is the sum of 90° and θ.
Angle θ can be found by working on the right triangle of side lengths 8 and 4, and angle θ.
We use the tangent ratio:
The opposite leg to θ is 4 and the adjacent leg is 8, thus:
Calculating the angle:
Thus the required angle is 90° + 26.6° = 116.6°
The angle between vectors A and B is 116.6°.

Answer:
x = 0.327 m
Explanation:
Block 2 of mass 1.00 kg is at rest
spring constant = 200 N/m
Block 1 of mass 2 kg moving at 4 m/s
m₁ v₁ = (m₁ + m₂)V
2 x 4 = (2 + 1) V
V = 2.67 m/s
loss of kinetic energy = gain elastic potential energy
x = 0.327 m
hence, the spring compressed distance is equal to x = 0.327 m
Chinook salmon work to maintain a stable internal environment despite changes in external conditions by the process called homeostasis. Homeostasis is important because salmon, like all living organisms, depend on the proper functioning of its cells to ensure its survival and the ability to reproduce.

Answer: The answer would be C. When Octopus eject the water out, the water acts with an equal force on the octopus in opposite direction.
Explanation:
An octopus propels itself forward in the water by ejecting water backward through a funnel in its body.
