perpendicular to the coil area. I would say and you don't actually know the magnetic flux since the area is not given, but a change in area is given.

I think it is the problem with "makes an angle of 50 degrees with the direction perpendicular to the coil" and magnetic flux is defined as BA not B delta A. The equation should be e.m.f = -N dBA/dt = -NBdA/dt where dA is the area changed.

I think you are right 5 times a day means 0.2 day for a complete revolution...

anyway, you can change the result of Newton ring. Just view at the bottom of the ring. the transmission of light should be opposite to the surface

I remember in the pase , both H-1 and O-16 were used to define the "relative" mass of other natural isotopes/atoms

By bernouili equation Pa+1/2pva^2 = Pb =1/2pvb^2 1/2pvb^2-1/2pva^2 =Pa-Pb deltaP = 1/2pvb^2-1/2pva^2 deltaP * A =Lift force I think your method is correct

of course, which is energetically favourable.

Indeed, these three factors are just provided you as explanations :)

An element of atomic number 82 and mass number 214 decays radioactively to an element of atomic number 82 and mass number 210. making use of mathematics. a beta decay got and increase in proton number but has no change in the mass number so. 214-210 = 4 => from 1 alpha decay 82-2 = 80 +2 = 82...

the acceleration is not directly proportional to the displacement but a constant acceleration (assume there is no air resistance) there is no equilibrium position between the extreme ends... (as well as force= 0) and the direction is downward besides at the pt where the ball rebounces... it is...

in fact, it(the effective force constant) can be written as 1 over summation 1/k

in theoretical degree, it is possible. by repeating the fractional distillation of a solution of ethanol and water, you will finally get about 96% of ethanol solution in terms of purity. Then, using CaO to help you remove the remained water. but in fact, it does not exsit. by both environmental...

Both. They have different angles in both the first and second maxima. c) (10^-2/6000)sintheta =n(520*10^-9) sintheta cannot exceed one so calculate the n your own you should calculate and do homework yourself. I am to guide you, not to help u finish your homework

it seems work to me...

sketch... I don't think you need to do that:devil:
