C. Space.
Radiation is a process by which heat energy is transferred through space.
Explanation:
a. Mechanical advantage = force out / force in
MA = 830 / 100
MA = 8.3
b. Efficiency = work out / work in
0.80 = W / 600 J
W = 480 J
The choices can be found elsewhere and as follows:
<span>a.
copper alloy or bronze casting were first used in Sub Saharan Africa.
b.
Islam became an economic and religious force in West and North Africa.
c.
that abstract thought in humans occurred much earlier than once thought.

Short Answer: YES
Long answer:
Density is generally regardless of how big or small a substance is and is neither dependant on its shape. A statue made of gold and a brick made of gold might have different masses and volume but they have same density.
By universal definition, density of a substance is the mass per unit volume.
D = Mass/Volume
