Answer:
Mass , momentum and mechanical energy
Explanation:
There are two types of collision.
1. Elastic collision: in case of elastic collision no energy is loss in form of heat and sound .
The momentum and the kinetic energy is conserved.
2. Inelastic collision: in case of inelastic or partially elastic collision, some of energy is lost in form of heat or sound. Here momentum and mechanical energy is conserved.
Mass of a system is always conserved.
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 .

<h3>The mass of the body is 7.38 kg</h3>
Given,
- Acceleration of the object = 3.4 m/s²
- Net force = 25.1 N
We need to find,
Using Newton's first law of motion .
- Force = Mass × Acceleration
➵ 25.1 = Mass × 3.4
➵ 25.1 ÷ 3.4 = Mass
➵ Mass = 7.38 kg
An electromagnet is a type of magnet in which the magnetic field is produced using the current. The simplest form of an electromagnet is a wire wrapped around in a coil.
The strength of magnetic field of such magnet is given with this equation:
Where N is the number of loops in the coil, I is the strength of the current flowing through the coil, L is the length of the coil, and
is <span>permeability of the electromagnet core material.
From this equation, we can see that increasing both the current and number of loops will increase the strength of the magnet.
Both BLANKS should be
Increase. When you use the additional battery you will have more voltage and more voltage means more electricity.</span>
