Question 5 [12 10 22 marks] (a) In a given inertial reference frame, S', consider a region of space where there is a uniform and constant electric field, E', and zero magnetic field, i.e. B' = 0. The frame S' moves with respect to an observer, in another frame S, with velocity v. Write an expression for the electric field, E, observed in S? Clearly explain any notation (i) and new quantities introduced Write an expression for the magnetic field,...

2.13 Conclusion The theoretical discovery of the Lorentz transformation was an important s the learning process leading to Special Relativity, but its deep meaning was understood before Einstein. In our presentation we have made it clear that the Lorentz transformation can be derived from the two postulates of Special Relativity, which are physically more transparent than what, at first sight, appears "only" as a mathematical transformation. From the physical point of view it is more...

3. Simultaneous? In a reference frame S two very evenly matched sprinters are lined up a distance L apart along the x axis for a race parallel to the y axis. Two starters, one beside each runner will fire their pistols at lightly different times, giving a handicap to the faster of the two sprinters. The time difference in the frame S is T (a) For what range of time differences will there be a reference frame S in which...

this is one question but with multiple choice questions,
sorry.
Problem 1 You're in a spaceship in deep space. Your engines are off, and you're far away from any reference points. a) You release a small ball from rest. The ball remains floating at rest in the same position where you released it. What kind of reference frame are you in? Is there any way to tell if you are moving at all? Let's designate your reference frame as S,...

Question 3 [20 marks] Water (density p1000 kg/m2; dynamic viscosity 0.001 Pa-s) flows steadily through a horizontal, straight pipe with circular cross section of diameter D=0.2 m. The volumetric flow rate is 0.01 m°/s. Argue that this is turbulent flow. [4 marksl а. Pressure drop in the pipe is due to friction. The pressure drop per unit length can be written as Др 4f L with U the average velocity in the pipe and fthe friction factor. Given the pipe...

x=L The rail gun consists of two thick conducting rails connected to a power supply and there is a magnetic field assumed to be uniform and constant in the direction shown. A short conducting bar that is to be (or carry) the projectile is placed across the bars at x -0. The current flows through the bars as shown. The magnetic force on the bar causes it...
