2) water friction or FLUID friction. LESS friction DUE to streamline shape.

As far as influencing local climate directly, I would SAY the two most important HUMAN activities are city building and AGRICULTURE.“Urban warming” is a phenomenon caused by replacing local vegetative cover with things like roads and highways, concrete bridges, brick buildings with asphalt roofs, and parking lots full of metal cars. All those things absorb sunlight, then radiate it back into the local atmosphere, often making it considerably hotter locally than it would be with trees and grass.In much the same way, agriculture CHANGES the GROUND cover. Cutting down a thick forest to plant grain, or grazing rich, green pastures to the point of barrenness, changes the way the ground absorbs and radiates the sun’s heat back into the local atmosphere.This gets at the heart of a two-pronged solution to climate change: planting trees. Trees not only take carbon dioxide out of the atmosphere in general, but they also provide locally sourced shade and ground cover.

Thermodynamic temperature is a measure of the kinetic energy in MOLECULES or ATOM s of a substance. ... The kelvin is the unit of temperature in the International System of Units ( SI ). One kelvin is FORMALLY DEFINED as 1/273.16 (3.6609 x 10 -3 ) of the thermodynamic temperature of the triple point of pure water (H 2 O).

The electric field of an electromagnetic wave in free space is given byE→ =10cos(10 7 t+kx) j^ V/m, where t and x are in seconds and metres RESPECTIVELY. It can be inferred that(i) the wavelength λ is 188.4 m.(ii) the wave number k is 0.33 rad/m.(III) the wave amplitude is 10 V/m.(iv) the wave is propagating along +x direction.Which one of the following pairs of statements is correct?MEDIUMHelp best friendStudy laterVIDEO EXPLANATIONANSWERAs given: E= 10cos(10 7 t+kx)COMPARING it with standard equation of e.m. wave,E= E 0 cos(ωt+kx)Amplitude, E 0 =10 V/m and ω=10 7 rad/s∵C=vλ= 2πωλ or λ= ω2πc = 10 7 2π×3×10 8 =188.4 MALSO,c= kω or k= cω = 3×10 8 10 7 = 0.033The wave is propagating along y direction.How satisfied are you with the answer?This will help us to improve betterMore Questions by difficultyEASYMEDIUMHARD

It is certain that fossil fuels are likely to be exhausted sooner or later. It is rather satisfying that Fossil Fuels sustained the global energy needs till date. Although there were no serious issues of this generation initially, gradual awareness on Environment posed many problems, over the last few DECADES. This awareness has gained considerable MOMENTUM with Climate change in the forefront.It is thus time for introspection on the way power is generated globally today and to address critical problems on hand. How long can we continue? OR are we to be seriously looking at options before us much more seriously than addressing them superficially?Here is an attempt answering some of the above questions:What are the options?Power plant managers of today need an open mind t all the FOLLOWING options for a BETTER and CONTINUED operation. In fact, many more novel ideas could stem from the experience we gain along, which may prove much more effective and therefore, plan periodically.Explanation:I hope it will help you :)

The higher the calorific VALUE of a fuel, the more is its EFFICIENCY. ... When a gaseous fuel burns, it gives off a great deal of energy. And unlike other SOLID and LIQUID fuels it does not leaves any ash. and it produces very little air pollution.

fficient of performance is given by,where is the heat USED and is work done.In the question,Then, coefficient of performance,Hence 4 is the answer. More about coefficient of performance:-The refrigerator is doing work in order to absorb a quantity of heat from sink  (objects in refrigerator) at low temperature and to supply a quantity of heat into SOURCE (ATMOSPHERE) at high temperature.Then work done is,Negative SIGN for is because the heat is absorbed by working substance.Thus coefficient of performance,For a carnot refrigerator,This implies, coefficient of performance,We can write coefficient of performance as,by dividing both numerator and denominator each by We KNOW that efficiency,Thus, coefficient of performance,

frictionThe force responsible for changing the state of MOTION of objects in all these examples is the force of FRICTION. It is the force of friction between the surface of the BALL and the ground that brings the moving ball to rest.A SIMPLE case of dynamic equilibrium occurs in constant velocity motion across a surface with kinetic friction. In such a situation, a force is applied in the direction of motion while the kinetic friction force exactly opposes the applied force.hope it is helpfulmake me as brineliest.....
