Consider the circuit shown in the following figure. The emf source has negligible internal resistance. The resistors have resistances R1 = 7.00 Ω and R2 = 2.00 Ω . The capacitor has capacitance C = 6.00 μF . When the capacitor is fully charged, the magnitude of the charge on its plates is Q = 31.0 μC

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
