I think it's a solar power might seem strange or futuristic but it's already quite common place you might have a solar powered quartz watch on your wrist or solar powered pocket calculator
optical density would increase the refraction angle going in to the material
there may be a relation between opt density and mass density ... kg/m^3
Answer:
Stars are forming in the spiral arms so there are high mass, hot, blue stars in the arms.
Explanation:
An example helps clarify the difference between an analysis, a deter- mination and ... departments analyze samples of water to determine the concentration of ... moles of Cu2+, and cylinder 2 contains 20 mL, or 2.0 × 10.
The heat developed can be calculated using the power rules as follows:
P = I x V = I^2 x R
First solution is to use the given values of I and R as follows:
P = I^2 x R = (2)^2 x 25 = 4 x 25 = 100 watt
Second solution is to use ohm's law to get V, then substitute to get the power as follows:
V = I x R = 2 x 25 = 50 volts
Power = V x I = 50 x 2 = 100 watt
