  1. How long does it take to reduce the capacitor's charge to 10 μ C ?

    the equation to consider is: q = qo e^- (t/RC) then e^(t/RC) = qo/q t/RC = ln(qo/q) t = RC ln(qo/q) t = 10^3*2x10^-5*ln(20/10) =1.386x10^-2 s

  2. The volume of a gas at 27◦ C and 0.32 atm is 29 mL. What volume will the same gas sample occupy at standard conditions?

    Supposing "standard conditions" to be 1 atm and 0◦ C : (29 mL) x (0.32 atm / 1 atm) x (273 K ) / (27 + 273) K = 8.4 mL

  3. A sample of gas in a closed container at a temperature of 83◦ C and a pressure of 8 atm is heated to 333◦ C . What pressure does the gas exert?

    (8 atm) x (333 + 273) K / (83 + 273) K = 13.618 = 14 atm

  7. A sphere block with a mass of 1 kg is pressed back against a spring ?

    With a frictionless surface, the ball merely slides (not rolls); the initial spring energy is converted into PE: ½kx² = mgh ½ * 500N/m * (0.25m)² = 1kg * 9.8m/s² * h → → h = 1.6 m
