Answer:
1) A> B, 2) A = B, 3) A> B
Explanation:
When a figure is given the number of significant figures to determine the precision or uncertainty the number
1) the uncertainty in the number with three significant figures is less than the number with two significant figures
statement A 2.6
statement B 2.57
A> B
2) decalration A
2,567 + 3,146 = 5,713
with two figures it remains
5.7
statement B
2.6 + 3.1 = 5.7
A = B
3) for the product the result is with the number that has the least significant figures
statement A
rectangles area
2.536 * 1.4 = 3.6
statement B
2.536 * 1.41 = 3.58
A> B
Stephen`s Law:
P = (Sigma) · A · e · T^4
P in = P out
e = 1 for blacktop;
1150 W = (Sigma) · T^4
(Sigma) = 5.669 · 10 ^(-8) W/m²K^4
T^4 = 1150 : ( 5.669 · 10^(-8) )
T^4 = 202.875 · 10^8
![T = \sqrt[4]{202.857 * 10 ^{8} }](https://tex.z-dn.net/?f=T%20%3D%20%20%5Csqrt%5B4%5D%7B202.857%20%2A%2010%20%5E%7B8%7D%20%7D%20)
T = 3.774 · 10² =
377.4 KAnswer: Equilibrium temperature is 377.4 K.
False) high intake of alcohol and sugar increases the triglycerides.
227kj Because The first thing to do here is to calculate the energy of a single photon of wavelength equal to
527 nm
, then use Avogadro's number to scale this up to the energy of a mole of such photons.
