A glass plummet weighs 14.35 g in air 5 points 11.40 g when immersed in water, and 8.95 g when immersed in sulfuric acid. Calcul
elena-s [515]

Answer:

0.865

Step-by-step explanation:

Specific gravity is a ratio of the weight of a substance to the weight of an equal volume of a substance chosen as a standard. The standard for liquid and solids is water while for gas is hydrogen.

Amount of displaced oil = 12.64 g — 9.12 g = 3.52 g

Amount of displaced water = 12.64 g — 8.57 g = 4.07 g

Specific gravity of oil = 3.52 g / 4.07 g = 0.865

Suppose given △ABD and △CBD.
patriot [66]

Answer:

The required result is proved with the help of angle bisector theorem.

Step-by-step explanation:

Given △ABD and △CBD, AE and CE are the angle bisectors. we have to prove that \frac{AD}{AB}=\frac{DC}{CB}

Angle bisector theorem states that an angle bisector of an angle of a Δ divides the opposite side in two segments that are proportional to the other two sides of triangle.

In ΔADB, AE is the angle bisector

∴ the ratio of the length of side DE to length BE is equal to the ratio of the line segment AD to the line segment AB.

\frac{DE}{EB}=\frac{AD}{AB}   →  (1)

In ΔDCB, CE is the angle bisector

∴ the ratio of the length of side DE to length BE is equal to the ratio of the line segment CD to the line segment CB.

\frac{DE}{EB}=\frac{CD}{CB}    →  (2)

From equation (1) and (2), we get

\frac{AD}{AB}=\frac{CD}{CB}

Hence Proved.

What is the constant of proportionality,<br> ?
zalisa [80]
The constant value (often written k) relating amounts that rise or fall uniformly together. It is the ratio of the amounts y and x: k = y/x. Put another way: y = kx. Example: you are paid $20 an hour.
