Answer:
The answer is 13 however make sure if they ask for a certain measurement like meter answer it by saying 13 meters.
Explanation:
This basically turns into basic algebra if you know the formula for work. The formula for work is W=F*d
Here are the variables that you know 650J=50N*d so you need d.
All you do is divide 650J by 50N and you get a total of 13 (meters since I don't know what they want you to put it in).
A possible source of indoor air pollution is a gas present in some carpets and furniture, which is Formaldehyde and VOCs .
Formaldehyde can cause Cancer due to its exposure through the Furniture. These cause pollution inside the room acting as Indoor Air pollution gas.
By the end of seven days the concentration of formaldehyde in household furniture can be brought back to normal in most of the cases.
Whereas it is also known that it takes about two years for a well furnished newly made home to bring down the levels of evolved gas i.e. formaldehyde.
The following types of cancers are prone due to Formaldehyde:
- Nose
- Throat
- Sinus
Some Volatile Organic Compounds (VOCs) are found in desks in office, cabinet furniture and several products available as furniture. These chemicals are used in manufacture of new carpets harming our health.
VOCs can be removed by using hot water of the given carpet. These cause pollution inside the room acting as Indoor Air pollution gas.
It usually takes two to three days to evolve off the gas.
Hence, a possible source of indoor air pollution is a gas present in some carpets and furniture, which is Formaldehyde and VOCs .

The force of attraction between the opposite charges of the ions in an ionic compound is an ionic bond.
<u>Explanation:</u>
The transfer process of valence electron between atoms referred as ionic bond. This is a kind of chemical bonds which can create two oppositely charged ions. In the presence of ionic bonds, the metal loses electrons and becomes a positive charge cation, while non-metal accepts these electrons and becomes a negative charge anion.
Here, more than 1 electron can be emitted or received to meet the octet principle and the net charge of the compound should be zero. For example: Table salt. In this compound, sodium loses the electron to become , while the chlorine loses the electron to become .
Answer:
98J
Explanation:
Given parameters:
Mass of rock = 5kg
Height = 2m
Unknown:
Work done = ?
Solution:
The amount of work done is given as:
Work done = Force x distance
Work done = Weight x height
Work done = mgH
Now insert the parameters and solve;
Work done = 5 x 9.8 x 2 = 98J
