Question 10 (1 point) You mix (4.00x10^2) cm of liquid 1, with a density of (1.00x10^0) g/cm3, and (3.5x10^2) cm3 of liquid 2, with a density of (8.500x10^-1) g/cm3. Calculate the average density in kg/m3 to 2 sf. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answer Question 11 (1 point) A travelling wave moving along a string has an equation of y(x,t) = (3.00x10^-3) cos ( (4.582x10^3)x -(5.9050x10^2)t ) Assuming all parameters are in SI units, calculate how far the wave propagates along the x-axis in (5.500x10^1) seconds. Calculate your answer in metres to 3.0 significant figures Note: Your answer is assumed to be reduced to the highest power possible. Your
