Answer:
Air drying
Explanation:
Sanitation is the set of measures that aims to preserve or modify the conditions of the environment in order to prevent diseases and promote health, improve the quality of life of the population and the productivity of the individual and facilitate economic activity. Basic sanitation is a right guaranteed by the Constitution as the set of services, infrastructure and operational installations for water supply, sanitary sewage, urban cleaning, urban drainage, solid waste and rainwater management.
Sanitation can be carried out in several ways, except for dry air, as this would damage the quality of sanitation and the environment.
Sanitation is important in treated water, sewage collection and treatment services lead to an improvement in the quality of people's lives, especially in child health, with a reduction in child mortality, improvements in education, in the expansion of tourism, in the valuation of properties, in income of the worker, in the cleaning of rivers and preservation of water resources, etc.
For the answer to the question above,
220 m/s
<span>mass of the bullet * velocity of the bullet = mass of the gun * velocity of the gun </span>
<span>0.005 kg * v = 0.52 kg * 2.1 m/s </span>
<span>-> v = (0.52kg * 2.1 m/s) / 0.005 kg = 218.4 m/s
</span>I hope my answer helped you. Have a nice day!
A vector is a quantity or phenomenon that has two independent properties: magnitude and direction.
Answer:
statement B is true
Explanation:
since same force is applied by the compressed spring on both masses so their rate of change of momenta must be same and since the lighter block has lesser mass so it must have greater velocity to have an equal change in momentum as of heavier mass.
By relation: 
, 
comparing momenta of above two equations we get
KElighter (2) = KEheavier (4)
KElighter = 2 KEheavier
