False. A Red Giant evolves from a main sequence star after it commences
Helium fusion and undergoes a great expansion; in the case of our Sun
it would expand to encompass Earth's orbit. Thus, it would have
approximately the same mass (a small amount being expelled in the helium
flash), and vastly greater volume, equating to vastly lower density.
You're welcome :)

Answer:
159241.048 cm³/s
Explanation:
r = Radius = 3×height = 3h
h = height = 16 cm
Height of the pile increases at a rate = 
Differentiating with respect to time
∴ Rate is the sand leaving the bin at that instant is 159241.048 cm³/s
Well, one example is that the weight of the rider puts downward force on the motorcycle, which is absorbed by the suspension or shocks or something.
Answer:
Temperature is also a condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.
Power = (voltage) x (current) =
(120 V) x (8 A) = <em>960 watts</em>
