The hypotheses that was tested in this experiment was diet explicitly comparing between herbivores and carnivores will determine eye size and mandible length. The null hypothesis for this experiment is that there will be no difference in jaw length and eye length when comparing carnivores and herbivores. The prediction for this experiment is that herbivores will have larger eye diameter in order to locate predators and carnivores will have shorter stronger

between the length of a cantilever‚ which may give some insight into the physics of cantilevers. Hypothesis: If one increases the length of a cantilever‚ one would expect there to be an increase in deflection/flexion of the cantilever. Similarly‚ if one increases the mass of the load‚ one would expect there to be an increase in the deflexion/flexion of the cantilever. In addition‚ I predict that proportionality will also occur between the independent and dependent variables. If the length of the cantilever

ways. So I will just give you a few examples. One example is that in softball and baseball each team has 9 players. These sports both have the same positions. A second example is that the bat length is about the same‚ the weight is not the same simply because girls just aren’t as strong as guys are. The bats length is usually around 31-34 inches. Then the last example is that each team

period of a pendulum depends on length‚ mass‚ and amplitude of the swing. THEORY A simple pendulum is an idealized model consisting of a point mass (sometimes called a pendulum bob) suspended by a massless unstretchable string. When the bob is pulled to one side of its straight down equilibrium position and released‚ it oscillates about the equilibrium position. The path of the bob is not a straight line but an arc of a circle with radius L equal to the length of the string. We use as our coordinate

or slower‚ I would prepare several masses (e.g. 20g‚ 50g‚ 100g‚ 200g‚ etc.) that can be attached to a string‚ several strings of varying lengths from 0.1m to 1.0m that are strong enough to support the weight of the masses‚ support for each pendulum‚ a stopwatch‚ and a measuring tool such as a meter stick. Using such materials‚ I would try to measure the length of the pendulum‚ the number of cycles the pendulum goes back and forth‚ the time it takes for the pendulum to do so‚ and the variables that

It is thought that‚ together with enzymes that methylate portions of native DNA‚ restriction enzymes protect cells from DNA of invading organisms cutting such DNA into pieces‚ thereby restricting its activity. In this experiment‚ using agarose gel electrophoresis‚ the number and relative positions of restriction sites for three restriction enzymes‚ EcoR1‚ HincII and PvuII‚ on the circular plasmid pBR322 were mapped by determining the length (in base pairs) of the

p. 4. An isosceles triangle has base 8cm and sloping sides both with length 10cm. What is the base angle of this triangle? Solution Split the base of the isosceles triangle in half. We now have a right-angled triangle of base 4cm and hypotenuse 10cm. We can now find the angle θ as follows A H 4 cos θ = 10 4 = 66.4218... = 66◦ to the nearest degree. 10 cos θ = θ = cos−1 5.
