Answer:
0.168°C
Explanation:
The frictional force between the palms enables rubbing and initiates the heat deposed.
The energy generated per rub is;
The force × distance
Hence we have; 71.3 N×0.0750m
Hence for 11 rubs we have; 11× 71.3 N×0.0750m= 58.82J
Now this heat acquired by the tissue is the same as mass of tissue × specific heat capacity of tissue × temperature rise;
Expressed mathematically as;
58.82=0.100 kg×3500 J/(kg · °C)×∆T
∆T= 58.82/ 0.100 ×3500 =0.168°C
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.
Answer:
Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.
