I believe that the correct given values are:
density = 755 kg/m^3
volume = 640 cm^3
First let us convert volume to m^3 units.
volume = 640 cm^3 * (1 m / 100 cm)^3 = 6.4 x 10^-4 m^3
so the mass is:
mass = 755 kg/m^3 * (6.4 x 10^-4 m^3)
<span>mass = 0.4832 kg = 483.2 g</span>
Answer:
b
Explanation:
it loses energy due to friction because if it hits objects the objects slow it down and which causes it to start slowing down
A). No. The entire poster is already covered with atoms,
but they're too small to see.
B). No. What's "life-size" of an atom ? It's too small to see,
and that's the whole problem.
D). No. Atoms are too small to see even with a microscope.
C). Yes ! A model of an atom, big enough to see, would help
get <em><u>some</u></em> of the important ideas across.
Answer:
When muscles are required to work harder than they're used to or in a different way, it's believed to cause microscopic damage to the muscle fibres, resulting in muscle soreness or stiffness. DOMS is often mistakenly believed to be caused by a build up of lactic acid, but lactic acid isn't involved in this process.
