Answer:
i believe there is something wrong in your question
Explanation:
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

Answer:
3.004A
Explanation:
The voltage across an inductor is expressed as:
![V=IX_L\\V=I(2\pi fL)](https://tex.z-dn.net/?f=V%3DIX_L%5C%5CV%3DI%282%5Cpi%20fL%29)
Given
f = 270Hz
V = 48V
L =0.053 H
Get the current
270 = I (2*3.14*270*0.053)
270 = 89.8668I
I = 270/89.8668
I = 3.004A
Hence the current in the inductor is 3.004A
