please do it in guss method no other way Solving problems in Physics, we must always use GUESS method.Guess stands for: Guess: G Here you write down what is given in the questionUnknown: U Here you list what you have to calculate, to solve for.Equations: E here you list all the formulas you need to use to solve the problemSubstitution: S This first letter S in the word, you will just substitute what is given in theformula. You do not calculate anything. The calculations will occur at the second S: Solve. Whatis very important here is to carry with you the units of measure in the formula. Not only thenumbers. This is very important, once again.Solve: S The last step, second S, you will solve what you plugged in the first S for Substitution.Very important here is to manipulate the units of measure such that the final units of measureto be proved by your work. This part is very important, since you will allow you to verify thatwhat you do is correct. For example, you calculate for…

For example, dimensional analysis could be used to determine the number of nickels in 3432.35 dollars. 34 dellar • To begin, write down the starting value, 3432.35 dollars. This can also be written as a fraction: Next, convert dollars to cents. This conversion involves a simple conversion factor: delar Note that the "dollar" unit should appear on the bottom of this conversion factor, since "dollars" appears on the top of the starting value. • Finally, convert cents to nickels. This conversion also involves a simple conversion factor. . This time "cents" should be on the bottom of the conversion factor, S centa since it was on top of the previous conversion factor. • Combining these expressions gives us 1 nickel 5 centa 3432.35 dollars ) (100 cente 1 dollar • Finally, cancel units. Since dollars are divided by dollars, and cents are divided by cents, both of these units can be canceled. Multiplying through gives the final result: 1 nickel 5 centis 3432.35 dollars 100 conts 68, 647…
