Aliquid has a specific gravity of 1.1 at room temperature. what is its (a) density at room temperature in kg/m3 (b) specific volume at room temperature in ft3/lbm? (c) if the liquid is placed in a 2 l bottle that has a mass of 157 g, how much will the full bottle weigh?

To solve this problem we will proceed to find the density from the specific gravity. Later we will find the specific volume as the inverse of the density. Finally with the data obtained we will find the total weight in the bottle.

a)

Here,

= Density

= Specific gravity

b)

From the equivalences of meters to feet and kilograms to pounds, we have to

Converting the previous value to British units:

c)

Mass of the liquid in bottle is

Therefore the Total weight

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
