Answer:
Us of agricultural fertilizers
Explanation:
Human activities account for over one-third of N2O emissions, most of which are due to the agricultural sector.
Answer:
Greater than
Explanation:
The Wavelength will be higher than what will be heard without any motion on the boat due to the Doppler Effect, which is the change in the frequency of a sound wave whenever there's a relative motion between the source of the wave and observer. The amount of shift in frequency depends on the speed of the source towards the observer; the higher the velocity of the source, the higher the shift.
Answer:
Abstract
A methodology for designing mechanical non-uniform motion generators is presented. The basic requirements for four-bar and six-bar linkages are established and it is shown how the performance can be evaluated by harmonic analysis applied to the output angular velocity function. A means of creating and searching a library of mechanisms based on normalized output functions is presented. B-spline curves are used as a means of defining a desired performance and it is shown how minimum acceleration can be achieved with continuity in the derivatives. Finally, a means of increasing the quality of motion transmission in the selected mechanisms is given. The techniques are used to synthesize a six-bar linkage.
A machine that provides both constant speed and maximum resistance throughout the full range of motion provides an isokinetic type of muscular contraction. This type of contraction occurs when the muscle would contract and shorten at a consistent and constant speed. To have this contraction, special equipment are to be used. An example of an equipment would be an <span>Isokinetic Dynamometer. </span>However, this type of training is said to be one of the fastest in increasing the muscle strength and the muscle endurance. With this training, the muscles being targeted would gain strength consistently and evenly throughout the whole duration of exercise.
