Physics Assignment for Class Xi

7. Draw a diagram of this set up. Use arrows to depict the movement of each substance in the

E. What would happen if you dropped the object into the beaker while using the Archimedes’ Principle method instead of submerging the object?

I will be doing this experiment to understand density of water compared to the volume of an object. D=m/v=mass/volume

9. Apply: Think about a small helium tank that can fill 50 balloons. What must be true about the helium in the tank compared to the helium in the balloons?

B. In Part I, when adding the needle to the water, which approach worked best to balance the needle on the water—the vertical or horizontal placement? Explain your answer.

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

Scaled radius of Mercury: 2.44 x 103 Km * (1 cm/6.96 x 104 Km) = 0.04 cm

heavy duty samples as well as your dimensional measurements (length and width in cm) from Part III of this experiment, calculate the height, or thickness, of each sample of aluminum using the formula V l x w x h. In the formula, V stands for volume, l for length, w for width, and h for height. Once again, you will have to use your algebraic skills to manipulate the formula, to solve for height. You must show all your work. (15 pts)

Step 2: The volume of both tanks is equivalent to 84,780. You utilize the recipe, and module the numbers to get the answer.

3. The volume of a fixed mass of a liquid sample increases as the temperature rises from 20 to

In order to minimize errors and to "place" the solutions in the same environment, the same volume should be extracted from each solution using the syringes.

2. Fill a flask with pure water (0% sugar), another with 0.2M water, another flask with 0.4 M water, and another flask with 0.8M water.

The volume of a small test tube and a thin-stemmed pipet were determined in this section of the lab. Water was poured into a small test tube until the water reached the very top edge of the test tube. The test tube was then emptied into a plastic 25 mL graduated cylinder and volume was measured and recorded into data table 3. A think-stemmed pipet was completely filled with water. Drops were carefully counted and emptied into the empty plastic 25 mL graduated cylinder until the water level reached 1 mL. The number of drops in 1 mL was recorded into data table 3. The thin-stemmed pipet had a total volume of 4 mL and that was also recorded into data table 3.

Task Description:The world communicates by making extensive use of the electromagnetic spectrum. For the average person this is commonly accessed using radio waves. These radio waves may be over the AM or FM radio wave bands or the radio waves that transmit our television signals. Not only are people always within a ‘phone call of each other anywhere in the world they are also able to find out exactly where in the world they are by use of

b) An empty beaker was weighted. Then, water was filled in the beaker. The temperature was recorded at uniform intervals.
