So you need to find the resulting length between the two distances. If you look at the two vectors as components of a right triangle then you can use Pythagorean theorem to solve for the last side. it is simply
which equals 165.5
Answer:
C = 74.53°
Explanation:
Let the magnitudes of 5.00 and 9.00 be vectors A and B respectively, hence the dot product of this vector is defined as
A.B = |A||B|cosC; let C be the angle between the vectors
12 = 5×9 cos C
Hence cos C = 12/45
C = cos^-1(12/45)
C = 74.53°
Answer:
The strategy we would like you to learn has five major steps: Focus the Problem, Physics Description, Plan a Solution, Execute the Plan, and Evaluate the Solution. Let's take a detailed look at each of these steps and then do an sample problem following the strategy.
Answer:

- <u> equal to the weight of the fluid that the body displaces</u>
Explanation:

<em>Archimides' principle </em>states the definition of buoyant force.
These are the imporant features of the buoyant force that you need to know:
- Except for the very special vacuum condition, every body is immersed in a fluid.
- The body is subject, at least, to two forces, its weight and the buoyant force.
- The weight is the result of the gravitational attraction exerted by the planet, and is equal to the mass of the object by the gravitational acceleration (approximately 9.8 m/s² on Earth). It is directed vertically downward.
- The <em>buoyant force </em>is the vertical upward force that the fluid exerts on the object and is equal to the weight of the volume of fluid displaced by the object.
- The volume of fluid that the body displaces is equal to the immersed volume of the body.
Acceleration represents the change in velocity.
