Two particles, both carrying charge 6 C are traveling parallel to each other with velocities of v⃗ =13000i^v→=13000i^ in m/s. They are positioned at the points (0,4,0)(0,4,0) and (0,−4,0)(0,−4,0). What is the magnitude and direction of the magnetic field at (0,4,0)(0,4,0) due to the particle located at (0,−4,0)(0,−4,0)? [Enter the magnitude in answer box 1 and the direction as one of either "in", "out", "up", "down", "left", or "right" in answer box 2. Assume that the xx-axis corresponds to left/right,...

A cue stick exerts a force of 200 N for 10?3 s to a stationary billiard ball (A) with mass m. Then this billiard ball (A) hits another billiard ball (B) with same mass and which is at rest initially. After the collision, the billiard ball (B) moves with a speed vB = p 2 m/s at an angle 45 degree with respect to the axis of the incoming ball (A). Assuming no friction between the billiard balls and the...

Problem #3: Biochemical Oxygen Demand (BOD) and Stream Quality A wastewater treatment plant designed for a community of 45,000 people has a flow of 100 gal/person/day and a BOD5 loading of 0.2 lb/person/day. The upstream characteristics of the receiving waters are: stream flow rate = 20 cfs and BOD5 = 2 mg/L The water quality standards require the in-stream BOD5 to be less than 7 mg/L in this stretch of the river. The minimum BOD removal efficiency that the treatment...
