Indicate which of the following are exact numbers. the mass of a stapler? i think its inexact because all staplers are different sizes. Is that correct? Also,the mass of a postage stamp. is that inexact? because they can also be diff. sizes?
Which of the following are exact numbers? a. There are 100 cm in 1 m. b. One meter equals 1.094 yard. c. We can use the equation: F=9/5 C + 32 to convert from Celsius to Fahrenheit temperature. Are the numbers 9/5 and 32 exact or
How much does 1 molecule of bromine weigh? I know the atomic mass for bromine is 79.90 g but I do not know how to use it to figure out the weight of the molecule. The given answer is 2.654x10^-22 but I do not know how to get
John goes to the store to buy some school supplies.He byus a stapler for $6.32, staples for $3.75, pencils for $2.00, and 2 packs of erasers for $0.99 each. He must pay $0.07 tax for every ($1.00)dollar he spends. How much does
A block with mass M rests on a frictionless surface and is connected to a horizontal spring of force constant k, the other end of which is attached to a wall. A second block with mass m rests on top of the first block. The
what is the mass of two moles of NaCl? You look up the exact numbers on the periodic table or some other chart. I will use approximations. 1 mol NaCl = 1 Na + 1 Cl = 23 + 35.5 = 58.5 grams. 1 mols NaCl, then, is 2 x 58.5 = ?? g.
Calculate the molar mass in gmol-1 of h3x.nh20 mass:2.07g volume:21.35 there are 2 equations for concentration: n(h3x.nh20)=c(h3x.nh20) x 250cm3/1000 n(h3x.nh20)= c(h3x.nh20) x 21.35/1000 multiply both sides and make the
In a certain lottery, five different numbers between 1 and 31 inclusive are drawn. These are the winning numbers. To win the lottery, a person must select the correct 5 numbers in the same exact order in which they were drawn.
Let f be a function that has derivatives of all orders for all real numbers. Assume f(0)=5, f'(0)=-3, f''(0)=1, and f'''(0)=4. Write the third-degree Taylor polynomial for h, where h(x) = integral of f(t)dt from 0 to x, about x=0
