In the figure puck 1 of mass m₁ = 0.50 kg is sent sliding across a frictionless lab bench, to undergo a one-dimensional elastic collision with stationary puck 2. Puck 2 then slides off the bench and lands a distance d from the base of the bench. Puck 1 rebounds from the collision and slides off the opposite edge of the bench, landing a distance 5d from the base of the bench. What is the mass of puck 2? (Hint: Be careful with signs.) -5 d- Number i |d- Units

C2 C1 XS R 5. From the figure above, a pair of charged capacitors are given C1 and C2 = 2 µF which are charged with a battery of 12 V. Determine then, how much charge between both capacitors is left after the switch has closed for over 1ms? How much is left for the capacitors C1 and C2? Lastly, determine the . 1 μF current of the circuit after this time.

Hi, I have a question regarding electromagnetism. The question is as follows:   An aluminum rod has a resistance of 1.590 Ω at 20.0°C. Calculate the resistance of the rod at 102°C by accounting for the changes in both the resistivity and the dimensions of the rod. The coefficient of linear expansion for aluminum is 24.0 ✕ 10-6 (°C)−1.
