Nope Copper is a better conductor
0.975 is correct, to get the answer you divide the length value by 10.
Answer:
SURE!!!...
But what to calculate!!!....
Answer:
Explanation:
mass of object = m
Mass of planet = M
Radius of planet = R
Height = h
Let the speed of the object as it hits the earth's surface is v.
the value of acceleration due to gravity
g = G M / R^2
where, g is the universal gravitational constant.
Use third equation of motion
where, u is the initial velocity which is equal to zero.
So, 
<span>Density
is a value for mass, such as kg, divided by a value for volume or area.
Density is a physical property of a substance that represents the mass of a certain substance per unit volume or unit area. From the problem statement, we are given the density of the living matter in a particular area and the area. To calculate mass, we simply multiply the area to the density. However, we should remember that the units should be homogeneous or the same and if not, we convert.
Mass = density x area
Mass = 0.10 g / cm^2 (0.125 ha) ( 1x10^8 cm^2 / 1 ha )
Mass = 1250000 g or 1250 kg</span>
