A sinusoidal electromagnetic wave is propagating in vacuum. At a given point P and at a particular time, the electric field is in the +x direction and the magnetic field is in the -y direction. If the intensity of the wave at point P is `p` W/m2, what is the rms electric field Erms at that point? (c = 3.00 × 108 m/s, μ0 = 4π × 10-7 T ∙ m/A, ε0 = 8.85 × 10-12 C2/N ∙ m2) Round your answer to 1 decimal place.

ABC is a straight line with AB = BC = 0.`d` nm. BP is perpendicular to ABC and BP = 0.80 nm. Charges of +3.2 × 10–19 C are placed at A and C, and a charge of –3.2 × 10–19 C is placed at B. Find the electric potential (units of Volts) at point P. Round to two decimal places.

Officers patrolling in vehicles can expedite response time to calls quicker than other means of patrolling such as foot, bike or horseback in rural areas. However the other modes of patrol can be better in dense populated or busy city areas.
