What factors effect the tipping of a car as it rounds a bend. Mass, Centre of mass, Velocity, and radius of curve, width of wheels. Am i missing anything?

Consider 2 players, of which 1 has one more coin than player 2. Both throw all their coins simultaneously and observe the number of heads. If all coins are fair what is the probability that player 1 obtains more coins than player 2? Equal a priori states same probability over all coins, 1/2...

spot on micromass. Can your method be generalised?

Im looking for a method of evaluating large logs without the use of a calculator, such as, log102750. Using properties of logs i can reduce the problem to 750*10y=2. However this requires an estimate on the value y which is going to incure a significant error in my final result. Im...

many thanks.:-)

Is there any method to show that their are infinitley many prime numbers?

Ok, so i have the 2nd part regarding the propogation vector. I can use the angle of refraction, from snells law, to find the x and y components of the transmitted waves propogation vector, with the new magnitude 3/2. As the mgnitude in meda one was 1. Howver i am still baffled with how i can...

I have 2 questions that need help with, Considering the following plane wave, E= 30 (0.866 i + 0.5k)exp{i(-0.5x + 0.866z)} firstly how can i deduce the direction of the electric field oscillations? And finally, if the wave is incident on a dielectric interface between medium of Er=2...

thanks

Trying to answer a question that state an experiment results shows uncertainty of 8 parts in 1010. Can anyone shed some light on the meaning. I don't understand. Thank you

Thank you for the reply. So the derivative of the sum of x's is invalid as x is undefined.i.e. the number of terms. Its time i brushed up on the rules of differentiation. Also you say the function is not well defined between R and R, can you explain what this means as i don't understand?

Ok, So i have a problem understanding conflicting results of a derivative, Consider the derivative of x2, which is 2x. However, if x2 is expressed as a sum of x's such that f(x) = x + x + x + x ... (x times), the derivative of f(x) becomes = 1 + 1 + 1 + 1 ... (x times.) = x Hence the...

i am new to the forum and am not farmiliar with the syntax for drawring shapes as of yet. i have been assuming that this problem can be solved, however it maybe that it can't and the answer is a proof that the criteria can't be met. Like i said i have no idea how to approach this except for...

yeah.

I am assuming the shapes must be asymmetrical or be combined to form an asymmetrical picture. This is because the intersect of the axis of symmetry due to the four shapes will form a point between the four shapes, preventing each individual shape from having at least one common border with the...
