Stokes' law is very important for preparing suspensions. On the subject, tick the correct alternative. A - According to Stokes' law, the larger the particles of solid particles, the greater the viscosity. B - The sedimentation velocity of particles in a suspension is inversely proportional to the diameter of the particles and directly proportional to the viscosity of the medium. C - The Stokes equation was based on an ideal condition, in which irregular particles in a little diluted suspension are deposited

A 45 grams (0.045 kg) golf ball of diameter equal to 43 mm fell into a 2m deep lake. Neglect inertia at the moment of impact. Assume viscosity of 1.12x10-3 Ns/m2 , water density of 1,000 kg/m3 and Cd=0.5. Sphere volume equals 4π r³ /3. 1. How long will it take from the moment it hits the surface until it gets to the bottom? 2. If one estimates the Cd with Cd=24/Re formula, the settling velocity would be unrealistically large. Why?
A tentative rule was given about tipping in Testing Experiment Table 8.4, where if a vertical line passing through the object's center of mass is within the object's area of support the object does not tip. According to the rule, the full box of crackers in the following experiment, which has a width of 13 cm and a height of 20 cm, was seen to tip at an angle of: θc=tan−1(13 cm/20 cm)=33∘θ According to the rule, at what angle will a box with the left half filled with crackers begin to tip? Assume the box is light-weight and that the contents remain in the configuration in
