Gold in its pure form is too soft to be used for most jewelry. Therefore, the gold is mixed with other metals to produce an allo
Novay_Z [31]

Answer:

Explanation:18kt alloy contains

i) 75% of gold

rhogold=19.3g/cm^3

=75/100×19.3

=14.475g/cm^3

ii) 16% of silver

rhosilver=10.5g/cm^3

=16/100×10.5

=1.68g/cm^3

iii) 9% of copper

rhocopper =8.90g/cm^3

=9/100×8.9

=0.801g/cm^3

Overall density of 18kt gold

=(0.801+1.68+14.475)g/cm^3

=16.956g/cm^3

=17g/cm^3 to 3s.f

what is the percent efficiency of a light bulb that emits 14 joules of light for every 60 joules of electric energy thst enters
jasenka [17]
If you're using the bulb as a source of light, then it's. 14/60 = 23.3% efficient.
If you're using it to heat a bird nest or a hamster cage, then it's. 46/60 = 76.7% efficient !
It just depends on your point of view, and what you consider 'useful' output.

The piece of wood shown above has a mass of 20 grams. Calculate its volume and density. Then
kozerog [31]

We have that The Density and Volume is given as

\rho=0.67\\\\\V=30cm^3

The factors that affect Density are Mass and Volume

From the question we are told that

The piece of wood shown above has a mass of 20 grams.

Wood parameters

2cm

5cm

3cm

Generally the equation for the Volume  is mathematically given as

V=L*B*H\\\\\V=2*5*3\\\\V=30cm^3

Generally the equation for the Density is mathematically given as

\rho=\frac{m}{v}\\\\\\rho=\frac{20}{30}\\\\\rho=0.67

Therefore the factors that affect Density are Mass and Volume
