Question 1 a) A 70 mm diameter and 0.20 m long cylindrical body slides vertically down in a 72 mm diameter cylindrical tube. The space between the cylindrical body and the tube wall is filled with oil of dynamic viscosity 2.5 Ns/m². Determine the velocity of fall of the cylindrical body if its weight is 16N.

1.1 A company compares two temperature instruments daily: one coupled to a processor computer and the other used for visual control. Day-to-day variation is expected. On each of three days, the two instruments are used to measure the temperature. Ideally, these two instruments should agree. How many factors are there in this experiment? What are they? List the levels for each factor.

Need help with these two questions. for the first question please do the whole conversion process. And include all steps and units please and thanks
