9. Calculate the mass of displaced water when a piece of 30
cm thick iceberg with surface area 1000 cm floats on
Gener
water (density of ice = 0.9 g/cm' and density of water = 1
gm/cm').

10. A rectangular body is dipped into water as shown in the
figure. The upper or lower surface area of it is 2 m´. Find out the upthrust acted
by water (density of water is 1000 kg/m'.

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit

If a balloon is taken outside on a very cold day, what will occur?

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.
