An electron is to be accelerated in a uniform electric field having a strength of 4.58×106 V/m. (a) What energy in keV is given to the electron if it is accelerated through 0.562 m? (b) Over what distance would it have to be accelerated to increase its energy by 58.0 GeV? Draw a diagram and show your parameters and all your work.

The elevator starts from rest at the first floor of the building and comes to a complete stop at the 6th floor. It can accelerate at 6 ft/s² and then decelerate at 2 ft/s² Determine the shortest time is takes to reach the 6th floor, which is 60 ft above the ground. Draw the v?t and s?t graphs for the motion of the elevator.

assume the shadow cost is $52 per hour. For B7, assume allocated fixed costs of $1391 and variable costs of $13 per unit. B7 uses 0.13 hours of inspector time per unit and has a demand curve of V = 1000 - 28P. What is the optimal price to charge for B7? The answer must be rounded to cents

QUESTION 2 In Derry v Peek 14 App.Cas. 337 (House of Lords, 1889) the Court held that there was not a fraudulent representation made by the tramway company. With reference to the issues before the court in that case, do you think that in 2020 it would be more desirable to sue under S 18 of the Australian Consumer Law? Explain your reasons.

9-25 l!:IJ Assume the auditor plans to test controls over the shipment and recording of sales transactions. Identify the controls that the auditor ,vould expect to find to achieve the objective that all transactions are recorded correctly, and in the correct period. For each control identified, indicate ho,v the auditor ,vould test whether the control operated effectively.

Let f(x) = −x^4 − 4x^3.

(i) Find the intervals of increase/decrease of f.

(ii) Find the local extrema of f (values and locations).

(iii) Determine the intervals of concavity.

(iv) Find the location of the inflection points of f.

(v) Sketch the graph of f. (You can choose your own scale for the graph)

a) Given a vector field à = zỹ +(3y + 2)2 î in cartesian coordinates, determine whether it is solenoidal (V · À = 0), conservative (D x X = 0)

ii) Calculate integral A*dl , where the contour C is the unit circle (r=1) traversed in anticlockwise direction

A uniform electric field is directed out of the page within a circular region of radius R = 2.50 cm. The magnitude of the electric field is given by E = (3.50 × 10-3 V/m•s)t, where t is in seconds. What is the magnitude of the magnetic field that is induced at radial distances (a)1.50 cm and (b)6.50 cm?
