Does A Heat engine work in cyclic process ? Is it possible to design one ? I read somewhere that an engine work in cyclic process and then I read it is not possible to design an heat engine which works in cyclic process and whose only result is to take heat from a body at a single temperature and convert it completely into mechanical work....

please help I am confused

is the formula for standing waves on super imposing -2a cos(wt) sin (kx) ?

I am doing an experiment with a group of friends. We are making a water aqua lens. ( Google it ). So I want you to hep me write something on it . Points for help can be 1) How it works ? Principle ?

2) Some less know facts . 3) futher use 4 ) introduction .

please help ............10 points will definately will be granted to best answer.

Forty students took part in a Mathematics Olympiad. They had to solve one problem in Algebra, one in Geometry and one in Trigonometry.

The results are tabulated below :

Problem Solved Number of students solving the problems

in algebra 20

in geometry 18

in trigonometry 18

in algebra and geometry 7

in algebra and trigonometry 8

in geometry and trigonometry 9

It is also known that three students did not solve a single problem. Find the number of students who solved all the three problems. Also find number of students who solved two problems.

If Z^2 is a complex number then y=root of Z^2 = +_ Z . Not just mod of z or z. Why ?

1) tan75 = 2 + √3

2) 1/ SecA + TanA = SecA-TanA

1+SinA - cosA / 1+SinA + cosA = tan(A/2)

1) tanθ + tanα / cotθ + cotα = tanθ × tanα

2) SinA/2 × Sin7A/2 + Sin3A/2 × Sin11A/2 = Sin2A × Sin5A

3) ( Cos3A + Cos5A ) + ( Cos7A + Cos15A )

Please Solve All Three problems

My sir said that in uniform circular motion accerleration is zero and there is constant speed but then he said that there is centipital acceleration due to centripital force . I am confused as how can acceleration be zero and then there is a centripal force ? Are they two different things ? (Explain)
