Texts: A monodisperse colloid of spherical silica particles with a diameter of approximately 1.0 μm in water at room temperature (25°C) has been produced using the Stöber method. If the particle concentration in the above dispersion is 0.01 vol%, the following calculations can be made: i) Assuming no particle aggregation, estimate the time required for the particles to settle to the bottom of a 10-cm deep vessel. The particle density is ρp = 2.10 g/cm³. ii) Again, assuming no aggregation, calculate the time required to centrifuge this colloid (i.e., settle out all the particles) in a 10-cm long centrifuge tube spun at 5,000 RPM about an axis 3.0 cm from the top of the tube. iii) Estimate the half-life, t1/2, of the dispersion with respect to rapid (Smoluchowski) aggregation. iv) Consider an aggregate of two of the above particles in "direct" contact. What is the probability that this aggregate will spontaneously break apart due to thermal agitation at T = 25°C? The relevant Hamaker constant is A = 10⁻¹⁹ J.

Use horizontal strips to find the area of the region enclosed by y = 0.75x and x = 3 - y^2. First find the y coordinates of the two points where y = 0.75x meets x = 3 - y^2. lower coordinate y = c = and upper coordinate y = d = [Give coordinates c and d accurate to three decimals.] Then, the area of the region = ?_c^d g(y) dy where g(y) = Evaluate the definite integral to find Area = ?_c^d g(y) dy =

COVID Vaccines: The table below shows the percentage of adults ages 16 to 24 from several countries who favor taking the COVID vaccine in their country. Country Total number of people surveyed % of people who are in favor of the vaccine United States 1002 51% Great Britain 1056 50% France 1102 48% Spain 1006 37% At $\alpha = 0.05$, can you support the claim that the proportion of adults in the United States who favor taking the COVID vaccine in their country is less than the proportion of adults in France who are in favor of the vaccine? Part a) P- value method. 1.) Identify the null and alternative hypotheses. Enter =, <, >, or \text{"not equal"} for $\neq$ $H_0: p_1 - p_2$ $H_1: p_1 - p_2$ 0 0 2.) Find the test statistic: Test Statistic = (Round to two decimal places) 3.) Find the p-value: p-value = (Round to four decimal places) 4.) State the decision about the null hypothesis. (Type Reject or Fail to Reject in the answer box.) $H_0$ 5.) Conclusion: There sufficient evidence that the proportion of adults in the United States who favor taking the COVID vaccine in their country is less than the proportion of adults in France who are in favor of the vaccine. (Type is or isn't into the answer box)
