Correct answers is D.
Explanation:
Reaction most often happens between two chemicals. But it can also happen with only one chemical. Heating of water is also a reaction.
When we heat the water we bring thermal energy to it. This causes raise of temperature and water starts boiling. This creates water vapour. In this way the amount of water in liquid and gas states changes. This eliminates answers B and C.
Freezing of water is also a reaction. When the water freezes it increases it's volume. This eliminates answer A.
Answer:
a. decrease by a factor of 3.
Explanation:
The intensity of light is inversely proportional to the square of distance.
I ∝1/d^2
or
I= k/d^2
where k is a constant
so, if d becomes 2d , I will be come I/4
Therefore, intensity will a. decrease by a factor of 3.
In my county Contra Costa County, California a property (with a value of greater than 15.00) left abandoned after 3 years the County needs to publish in a newspaper the location of the property and try and locate the lawful owners. Often their may be unpaid property taxes and penalties that need to be paid if the owner is found and wishes to reclaim the property. Sometimes due to deaths of previous owners without a trust or will it is difficult to find if their are any heirs to the property. If no one responds within 45 days of the publication the property will belong to the county and no longer claimed. If you feel you have any property or cash that belongs to you every State has a government site called unclaimed property. You can put in your name or a relatives name and if it belongs to you there is a form to be filled out and if you are the rightful owner you will receive it.
To solve this problem it is necessary to apply the concepts related to the centripetal Force, the Force of the weight produced by the gravity of the star and the definition of the velocity as a function of time (period)
In other words, for balance to exist, the force acting on the body (weight) must be equal to the centripetal force that attracts it in motion. That is to say
The value of the given period is 110min or 6600s.
At the same time we know that the speed of a body depending on its period (simple harmonic movement) is subject to
Finally, replacing this value in the event of gravity we have to
