HELP!!! I keep getting this question wrong and I dont know why! The answer I get is 0.011m^3?!
Because gasoline is less dense than water, drums containing gasoline will float in water. Suppose a 300-L steel drum is completely full of gasoline.
What total volume of steel can be used in making the drum if the gasoline-filled drum is to float in fresh water?
Express your answer using two significant figures.
Homework Answers
Gasoline and steel densities have range of values. So the final answer will depend upon selection of density value. I have taken avarage values.

For the BJT bias circuit shown, what value of Rc in kilohms is needed to allow the maximum possible peak-to-peak signal swing on the collector without clipping? Use Vcc-9V, Vee--7V, Vb-1.2V, and Re -9.9k2. Assume that to keep the transistor in the forward-active region, the base-collector junction cannot be forward biased. Use B 20 and Vbe(on) 0.7V. Neglect the effects of base-width modulation. Vcc...

Equivalent forces derivation problem. Derive the formula for F_3 in terms of the experimentally measured quantities m_1, m_2, theta_1, and theta_2 [Answer: F_3 = m_1 gcostheta_1 + m_2gcostheta_2.] Make sure you understand how this formula was derived.
