Answer:
See explanation
Explanation:
Since no figure was given, I'll explain how to theoretically solve this problem.
When a pin is resolved it has 2 reaction forces, one in the horizontal direction and one in the vertical. For this problem you could name these Ax and Ay. These two forces will act where the pin is, with Ax acting in the horizontal direction and Ay acting in the vertical.
When a rocker is resolved, it has one reaction force that acts perpendicular to the surface the rocker is on. This force can be thought of as B and it acts where the rocker is.
If you are determining the value of Ax, Ay, and B you should use static equilibrium and data given on the figure to solve for the reaction forces. The equations for static equilibrium (2D) are
,
, and
.
Answer: Advertising acts in a method similar to a fee. People who watch TV broadcasts must watch ADs. TV stations turn this into money by selling airtime to advertisers.
Explanation:
A non-rival good is a good whose consumption by one person does not reduce the remaining quantity available. An example is a street light.
For non-excludable goods, it is impossible to prevent everyone from enjoying the benefits of the good. An example is a lighthouse. This is where the free rider problem comes in.
A free rider is someone enjoying the benefits of a good without paying for it. When a good is both non-rival and non-excludable, it is convenient for consumers to enjoy the benefit without paying for it.
If TV broadcasts are both non-rival and non-excludable, everybody can choose to become a free rider. Advertising can solve this problem by converting free riders to potential buyers of goods or services advertised during broadcasts. This way, stations can generate revenue by selling airtime.

Answer:
Vector C = 1.334i + 8.671j + 2k or 1.334x + 8.671y + 2z
Explanation:
The concept applied to solve the question is cross product of vector, AXB since vector C is perpendicular to vector A and B and this is solved by applying the 3X3 determinant method.
