Textbook Question
Chapter 1, Problem 1.1DQ
How many correct experiments do we need to disprove theory? How many do we need to prove a theory? Explain.
Expert Solution & Answer
To determine
The number of experiments required to validate any theory.
Answer to Problem 1.1DQ
Any experiment is based on one or another theory and these theories are the combinations of various known facts and various non practical hypothesis of virtual science. Due to certain set of condition and parameters, a particular theory is designed and it changes from time to time and person to person depending upon perception of individual for the same incident.
Explanation of Solution
Any theory derived for any incident is based on certain set of conditions like physical value, apparatus used, method of processing and surrounding. These theories changes by changing any of the factor in the respective way. One cannot validate any theory by certain combination of experiment because by the change of any factor the experiment will not give the same result as it needs to be.
Conclusion: Therefore, there is no definite number of experiments that needs to perform for the validation of any theory as right and wrong

- 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)?arrow_forwardCan the table be solved for and explained?

The shape of a city is roughly a circle with a radius of 5 miles. If the population density for the city is 10,000 people per square mile, what is the population of the city? 11111 Now here's a problem that will stretch your problem solving skills. This time the city is also in the shape of a circle, but the population density is higher towards the center of the city and lower towards the outskirts. The numbers in the diagram represent miles. The population density is 10,000 people per square mile in the inner circle. In the first ring out from the center the density is 8,000 people per square mile, the second ring out it's 6,000, in the third ring out it's 4,000 and in the largest ring it's only 2,000 people per square mile.
