Answer:
water can be used as displacement to calculate the volume of a solid object.
Answer:
magnitude = 161.3m, ∅ = 32.9°
Explanation:
Vector addition always works the same. Add two vectors by adding their respective components.
vector A: ![\left[\begin{array}{c}85.0&0.0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D85.0%260.0%5Cend%7Barray%7D%5Cright%5D)
vector B:![101.0\left[\begin{array}{c} cos60.0&sin 60.0\end{array}\right] =\left[\begin{array}{c}50.5&87.5\end{array}\right]](https://tex.z-dn.net/?f=101.0%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D%20cos60.0%26sin%2060.0%5Cend%7Barray%7D%5Cright%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D50.5%2687.5%5Cend%7Barray%7D%5Cright%5D)
Adding vector A and B: ![\left[\begin{array}{c}85.0&0.0\end{array}\right] +\left[\begin{array}{c}50.5&87.5\end{array}\right] = \left[\begin{array}{c}135.5&87.5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D85.0%260.0%5Cend%7Barray%7D%5Cright%5D%20%2B%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D50.5%2687.5%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D135.5%2687.5%5Cend%7Barray%7D%5Cright%5D)
The magnitude of any vector
is given by the Pythagorean theorem:

In the case of the vector A+B:

The angle ∅ of the vector can by found by using trigonometric functions:
For instance, the angle ∅ for a vector
is given by the equation:

The direction ∅ can be found by solving the trigonometric function.
In the example of vector A+B:

Solving for ∅:

So when two forces act in opposite directions, they combine by subtraction. If one force is greater than the other force, the overall force is in the direction of the greater force. Overall Force. In any situation, the overall force on an object after all the forces are added together is called the net force.
