That statement may be considered true. 'Specific gravity' is the ratio of
the density of a substance to the density of a reference substance. The
reference substance is nearly always water, and the ratio of the density
of water to the density of water is obviously ' 1'. So there you are.
Answer:
Elastic potential energy store - which is the energy transferred to a spring as it's stretched.
Answer:
Explanation:
A wonderful (NOT) mixed unit problem
convert mph to m/s
v = 10 mi/hr(5280 ft/mi)(12 in/ft)(2.54 cm/in) / (100 cm/m) / (3600 s/hr)
v = 4.4704 m/s
KE = ½(0.006)4.4704²
KE = 0.05995342848 J
KE = 0.06 J
<span>The speed of light changes as it passes from one medium to another medium due to the difference in the density of the two media. This is the reason for refraction of light also.</span>
