Acontainer weighs 8 lb when empty, 49 lb when filled with water, and 58 lb when filled with glycerin. find the specific gravity of the glycerin.

1.185

Explanation:

Hello

The specific gravity, consists of the ratio  that exists between the density of one substance and the density of another reference substance(water) ,the water is used in this case.

The specific weight of a substance is defined as its weight per unit volume

Let

Step 1

find the weight of the  water

(1)weight of the container= 8 lb

(2)weight of the container + weight of the water=49 lb

from(2)

weight of the water=49 lb -weight of the container

weight of the water=49 lb -8 lb

weight of the water=41 lb

Step 2

find the volume of the container using the weight of the water

the volume of the water = volumen of the container

Step 3

Find the weight of the glycerin

(1)weight of the container= 8 lb

(3)weight of the container + weight of the glycerin=58 lb

from(3)

weight of the glycerin=58 lb -weight of the container

weight of the glycerin=58 lb -8 lb

weight of the glycerin=50 lb

Step 4

Find the weight of the glycerin

Step 5

find the specific gravity if the glycerin

have a great day

i think i backed my dad

a true.

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.
