I am not sure what you are asking but..: A series circuit is a circuit with 2 or more bulbs or lights to light. In a series circuit when you take out one bulb (or one goes out) the rest go out as well. A parallel circuit is still multiple lights, but because of the way it is set up makes it so when you take out one bulb (or one goes out) all of the rest stay lit.
Answer:
D. The total energy of a system can increase only if energy enters the
system
energy must be conserved--it cannot be created or destroyed.
so, if the energy of a system increases, that energy must have come from somewhere
hope this helps!!
The variety of species in an ecosystem is known as biodiversity.
Answer:
The change in temperature of 576.9°C will produce an elongation of 9 inches per feet in steel.
Explanation:
The formula for linear expansion of a material is:
ΔL = αLΔT
where, ΔL = change in length
L = Original length
ΔT = Change in temperature
α = coefficient of linear expansion
For steel, α = 13 x 10^-6 /°C
L = 100 ft
ΔL = (9 in)(1 ft/12 in) = 0.75 ft
Therefore,
0.75 ft = (13 x 10^-6 /°C)(100 ft)ΔT
<u>ΔT = 576.9°C</u>
