On introducing a polarimeter tube 40 decimeter long and containing sugar solution of unknown strength, it is found that the plane of polarization is rotated through angle 25o. Find the strength of sugar solution in gm /cm3 . Specific rotation of sugar solution 50o per centimeter per unit concentration.
Answers
Answer:
( ELECTROMAGNETIC,LIGHT) - OR POLARIZATION - AS IT PASSES THROUGH AN OPTICALLY ACTIVE FLUID SUCH AS SUCROSE WHICH IS NEARLY IDEAL SUGAR FOR TESTING AND CALIBRATION. THAT'S WHY SUCROSE SOLUTION IS USED FOR CALIBRATION OF POLARIMETER.
Explanation:
Measuring principle
A polarimeter is an instrument which measures the angle of rotation by passing polarized light through an optically active (chiral) substance. To measure optical rotation, a Light Emitting Diode (LED) produces a beam of ordinary light.
Answer:
In the aerospace industry, a frustum is the fairing between two stages of a multistage rocket (such as the Saturn V), which is shaped like a truncated cone.
...
The conical Frustum formulas in terms of r and h is as follows: Volume of a conical frustum = V = (1/3) * π * h * (r12 + r22 + (r1 * r2)).In geometry, a frustum (plural: frusta or frustums) is the portion of a solid (normally a cone or pyramid) that lies between one or two parallel planes cutting it. A right frustum is a parallel truncation of a right pyramid or right cone.
Explanation:
To find a unit vector with the same direction as a given vector, we divide by the magnitude of the vector. For example, consider the vector v = (1, 3) which has a magnitude of . If we divide each component of v by we will get the unit vector uv which is in the same direction as v
