You have been given a block of some kind of plastic.  The block floats when placed in water but it sinks when placed in alcohol.  In which liquid is the buoyant force greater?     In the water     In the alcohol     Same block, same buoyant force     The material of the block needs to be known to answer the question.

A 1.00-MΩ voltmeter is placed in parallel with a 75.0-k Ω resistor in a circuit.                                                                                                            (a) Draw a circuit diagram of the connection. (b) What is the resistance of the combination?(c) If the voltage across the combination is kept the same as it was across the 75.0-k Ω resistor alone, what is the percent increase in current?(d) If the current through the combination is kept the same as it was through the 75.0-k Ω resistor alone, what is the percentage decrease in voltage? (e) Are the changes found in parts (c) and (d) significant? Discuss.
