the upward force the desk pushes on the book.
from the free body diagram of the book, it is clear that on the book, there are two forces acting.
1) normal force F by the desk in Upward direction.
2) force of gravity by earth in downward direction.
The Upward normal force by the desk on the book balances the force of gravity by earth in downward direction. that is why the book remains stationary on the desk.
Answer:
Explanation:
Six waves passes by under 60second interval
Since it has 6 waves,
Then, it correspond to 3 wavelength
Then,
The period of each Each wavelength is 60 / 3
Then, period = 20seconds
From the relationship between frequency and period
f = 1 / T
f = 1 / 20
f = 0.05 Hz
The most common price control is setting a fixed rent price to protect the tenants. There are other alternatives to this price control. Also, price control should be carefully implemented.
Rent regulation is a term that refers to a set of laws that focus on ensuring that individuals have access to rented housing.
The rental regulation system has a principe that is:
- Price controls: Set a rent price and set the increase in a percentage of it (the rent is $ 100 and the annual increase is 5%)
There are alternatives price control such as:
- Price according to the type of property: Set a rental price according to the type of property and its benefits (for example pool, garage, garden, etc)
- Price according to the number of tenants: Set a rental price according to the number of people who will inhabit the property
Generally, tenants are allowed to raise the value of the rent each year by a minimal proportion. This is necessary to avoid that the landlord does not increase the rental value in large amounts because the tenant will not have access to the rented house.
However, governments should be careful with this regulations because they can negative afect the landlord by limiting his rights over the property.

The gravitational force between two objects doesn't ONLY depend on the product of their masses. It also depends on the distance between them.
I'm not even going to work out the numbers for my example. I'm just going to state without proof that at the top of the 2nd frame, the gravitational force between you and your bowling ball is greater than the gravitational force between you and the whole darn Andromeda galaxy ! My reasoning is based on the fact that your bowling ball is maybe 1 foot from your center of mass, whereas the Andromeda galaxy is more like 2.5 million light years from it. That right there is going to give your bowling ball a big advantage when it comes to gravity !
