A spring has a relaxed length of 26 cm (0.26 m) and its spring stiffness is 11 n/m. you glue a 69 gram block (0.069 kg) to the t

op of the spring, and push the block down, compressing the spring so its total length is 16 cm. you make sure the block is at rest, then at time t = 0 you quickly move your hand away. the block begins to move upward, because the upward force on the block by the spring is greater than the downward force on the block by the earth. calculate approximately y vs. time for the block during a 0.27-second interval after you release the block, by applying the momentum principle in three steps each of 0.09-second duration.

Which parameter best defines the primary difference between weather and climate?
LenKa [72]

Answer:

time

Explanation:

weather is the atmospheric condition of a place over a short period of time, while climate is the weather condition prevailing in an area over a long period of time. From the two definitions above we can see that weather is the condition over a short period of time while climate is over longer periods, therefore the primary difference between them is time.

Readme [11.4K]

An electric motor has an effective resistance of 29. 4 ω and an inductive reactance of 42. 6 ω. When working under load. the rms voltage across the alternating source is 442 v.  The rms current will be  8.54 A

AC stands for “Alternating Current,” meaning voltage or current that changes polarity or direction, respectively, over time. AC electromechanical generators, known as alternators, are of simpler construction than DC electromechanical generators.

RMS or root mean square current/voltage of the alternating current/voltage represents the D.C current/voltage that dissipates the same amount of power as the average power dissipated by the alternating current/voltage. For sinusoidal oscillations, the RMS value equals peak value divided by the square root of 2.

I (RMS) = RMS voltage / \sqrt{R^{2}+ X_{L} { ^{2}  }

           =  442 / \sqrt{29.4^{2} + 42.6^{2}  }

           = 442 / \sqrt{864.36 + 1814.76}

           = 442 / \sqrt{2679.12}

           = 8.54 A

Sanitation can be accomplished by all of the means except
Nonamiya [84]

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.
