- This is a multiple question with 4 parts so all parts need to be answered & not against community guidelines. You can just give me the number of the question and the letter of the answer that goes with it.PLEASE HELP ASAP. PHYSICS ALGEBRA With exact decimals!One mole of Gold (Au) atom has a mass of 197 g. We know that the density of gold is 19.30 g/cm3 in room temperature. Using those numbers, answer the following questions: a) What is the mass of a single gold atom in kg? b) Assume that gold atoms sit in a perfect cubic crystal structure. Estimate the distance between two gold atoms in meters. c) If we have a gold cube of 6 cm on each side, how many atoms can we fit along the edge of each side of the cube? d) What would be the mass, in kilograms, of the gold cube we discussed in part (c) (measuring 6 cm on each side)?
- (a) A car speedometer has a 5% uncertainty. What is the range of possible speeds when it reads 90 km/h? (b) Convert this range to miles per hour. Note 1 km = 0.6214 mi.Can the table be solved for and explained? I answered the uncertainty correctly but I am not sure where I am going wrong in the begining.Please solve correctly. Thank you!!

What is the implied precision of the number 1.928×10^4 s? A. The number is precise to the nearest hundred seconds B. The number is precise to the nearest second. C. The number is precise to the nearest ten secondsa) You wish to compare the two experimental results the physicist got, so you decide to find the percent difference between these two values using the standard equation you learned in physics class: Substitute the following values for E1 and E2 and calculate the percent difference using the formula given below: E1 9.96 m/s2 E2 9.72 m/s2 Percent differnce___Determine the absolute uncertainty for the calculated value in the following scenarios. Express as (computed result) ± (absolute uncertainty) (units). You measure the volume of a stainless steel sphere by placing it into a100 mL graduated cylinder with an uncertainty of 1 mL, with 20 mL ofwater initially. After the sphere settles, the graduated cylinder now reads22 mL. What is the volume with uncertainty? Please use the formula I posted ! Thank you!
