Total Solids and Carbohydrates
Total Solids
The dried matter that remains after moisture removal is
commonly referred to as total solids.
TS = 100 - Moisture
Total Soluble Solids
The part of total solid soluble in water constitute the total soluble
solid

22.7 polarization
The electric field oscillates along a direction perpendicular to the
direction of wave travel
The direction of the E field defines the polarization of the EM wave
A single EM wave is linearly polarized

NORMAL SOLUTION
Section I
A normal solution is a solution that contains an equivalent weight of solute in one liter of solution.
The mathematical expression is given in Eq. 1.

NAME _
1. A rectangular loop of wire is 20 30 . It has a resistance of 0.5 and a mass of 3 . Gravity causes
this loop to fall vertically into a magnetic field. The magnetic field has a strength of 2 and is directed
perpendicular to the loop (into the page

1. Drawings. Physics is about real things and you must at least have a mental picture of
a situation before using Physics to analyze it. An actual drawing is even better, and
can be an aid in underst

1. A circuit composed of resistors and inductors is shown here. Because of Faradays law and Lenzs law, the
current in an inductor cannot change instantaneously. When the switch is open, the circuit is not complete and
all of the labeled currents ar
