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:
a) 89300
b)
Explanation:
To find the Reynolds number, we use the formula:
Re = VD / v
Therefore, For part (a)
we are given:
D= 0.1
V= 10 * 0.1(m/s) = 1m/s
Substituting the figures in the formula, we have:
Re = 89,300
For part (b)
We are given:
;
;
Therefore,
;
Explanation:
is it that they all have wires

A
Explanation:
because Farmers in hilly areas grow crops on terraces built on the hillsides.
Answer:
Length of beam = 10in
Explanation:
We first calculate the maximum shear force.
Calculating for V, we have:
V = 3200Ib
P = 3200 *2
P = 6.4k
Let's now use the equation for the load for a length.
Using the stress equation,
Inputting figures in the equation, we have:
Solving for L, we have:
L = 10in
Length of beam will = 10in
