From the data sheet, the de Broglie wavelength, 𝜆 = h/p = h/(mv) The electron wavelength equals the proton wavelength so: 𝜆 e = 𝜆 p So: h/(m e v e ) = h/(m p v p ) m e v e = m p v p so the electron speed , v...

First, the surds need to be simplified. Surds can be simplified by finding the highest square number that is a factor of the number in the square root.√12 = √(4 x 3) = √4 x √3 = 2√3√75 = √(25 x 3) = √25 x √3...

For nearly three months, the formerly globe-trotting French president has scarcely left the country. Instead he has cleared his diary to criss-cross France, staging nearly a dozen town-hall meetings in a “gr...

This is usually a good idea if you have an integral with two functions multiplied together when one of the functions differentiates to a constant (could take more than one differentiation).For example to fin...

In An Inspector Calls Priestley explores both social and personal responsibility throughout. We can define social responsibility in this instance, as a belief in helping people who may be less fortunate than...
