In order to determine the maximum speed of an emitted electron, we must first find it's kinetic energy from the energy of an incident photon and the work function of the metal surface (the minimum energy ...

The total area of the circle is pi*r^2 = 36 piThis means that the sector is 1/12th of a circle.A circle has 360 degrees and so the angle of the sector wil be 360/12 = 30 degrees.

Roads may become unstable or dangerous near cliff edges, the building of safer ones inland can increase traffic due to large, slow vehicles going to or from the work site. This may increase noise and air ...

The force of resistance should be taken away from the driving force to result in a total force of 900N driving forwards.Then use F=ma, rearranged so that a = F/m, to result in an acceleration of 1.34 m/s^...

Theatre in Jacobean England acted as a form of didactic allegory, namely a means of teaching the public social lessons. In the case of William Shakespeare's 1605 play Othello, the play emphasises...
