Density- It is a measurement of that how material is packed together tightly.

Its formula is ρ=m/v

where ρ is the density of material

m is the mass

v is the volume  

here we have to find the length of cube's side

a cube of silver has a mass = 21 kg. = 21×10³ [∵1kg = 1000g ]

density of silver = 10.49g/cm³

the length of the cube's side = ?

v=m/ρ

l³ = 21×10³ /10.49 ≈ 2×10³ cm³

l =∛(2×10³)cm³

l = 1.26 ×10 = 12.6 cm

l = 4.96 inches                                       [∵ 1 cm = 0.394 inch ]

the length of the cube's side is 4.96 inches

fgiga [73]

Answer:

Hi,

The correct answer option is; D. Most of the current will flow through one part of the circuit.

Explanation:

A short circuit is a low resistance path in an electric connection between two conductors supplying current in a circuit.

It happens when excess amounts of current flow in the power source through a 'short path'.

Short circuits occur at very high temperatures which is of course caused by the heat produced during dissipation.

An example of application of short circuit is arc welding, where heating is achieved through short circuit.
