A block of mass m2=20.0kg on a frictionless horizontal surface is connected to a ball of mass m1=10.0kg by a lightweight cord over a lightweight frictionless pulley. A force of magnitude F=200.0N at an angle=27° with the horizontal is applied to the block slides to the right. Determine the magnitude of the acceleration of the two objects and the tension on the rope? KPa=0.3

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
