The effects of surface type on the number of bounces Question How does the surface type affect the number of bounces of a tennis ball? Hypothesis If we drop the ball on a softer surface‚ then it will bounce less times than on a hard one. Materials List Floor Jacket Desk Binder (x2) Tennis ball Slow motion camera (phone) Metre stick Procedure Set up equipment (listed above). Drop the ball from a height of 1 metre on the first surface. Film the drop (in slow motion). Count and record the bounces

Surface Tension of Water I. Purpose How does adding soap to water change its surface tension? II. Background Adhesion is the bond between two substances of different makeups. In water‚ adhesion allows it to stick to other surfaces. Cohesion is the bond between two of the same substances. A hydrogen bond is a type of cohesion in water in which the hydrogen atoms of one water molecule being attracted to the oxygen atom of another water molecule. In water‚ each molecule in the middle is pulled

Their government talked to the aliens and made a deal every 1000 years there would be a competition. 10 humans and 10 aliens would compete to the death‚ and whichever side won would be able to live on the surface again.

The concrete and numerical data provided by this report will be helpful in shaping the relationship between the Internet of Things to the hierarchy of social class – specifically the lower working class. Firstly‚ this report can be understood sociologically because it utilizes one of the most important methods used by sociologists:

affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with the acid. This is because the acid only comes in contact with the particles on the surface of the donut. But‚ if you crush

Skimming the Surface of Babbitt Not all of us can have a great escape with that fairy child in our dreams. In Chapter 1 part II of the satirical phenomenon‚ Babbitt‚ by Sinclair Lewis; he really gives you something to ponder. In the previous section Lewis had just ended saying how the city of Zenith was “built-it seemed- for giants”‚ putting this city on a pedestal for its community. This statement is already mocking the citizens of Zenith who are materialistic middle-classmen‚ like Babbitt

between the rate of reaction and the surface area. The larger the surface are‚ the faster the rate of reaction seems to be. However‚ although the grain with the largest surface area (the smallest grain) reached the highest point within the shortest amount of time‚ its end result was still lower then the medium sized grain. The explanation for this result is relatively easy. The rate of a chemical reaction can be increased by increasing the size of the surface area to volume ratio of the solid reactant
