Suze

Assume that 64.0 cal of heat is applied to a 14 g sample of sulfur at 16°C. What is the final temperature of the sample if the specific heat of sulfur is 0.175 cal/(g·°C)?

Let N N denote the natural numbers {1,2,3,4,...}. Observe a f that satisfies f(1)=1, f(2n)=f(n), f(2n+1)=f(2n)+1 for all n that are natural numbers. Write a algorithm for f(n).

Answer

AB:BC=3:4, so AC=AB+BC=3+4=7; AC:CD=2:1, so AC=2; because we get 2 different length for AC, we change the given ratio AC:CD into an equivalent one where AC=7 as follows: AC:CD = 2 : 1 = 7 : 3.5 (multiply both sides by 3.5) Now we have AC:CD = 7 : 3.5 and...
