The angle of the drop height was at 90 degrees and the length of the string was at 300 mm.

Angle or Drop Height: Hypothesis: I predict that the larger the angle of drop, the longer period of the pendulum. The independent variable is the drop height. The mass of the pendulum was 100 grams and the string measured 300 mm.
Number – 19g average mass 1.7g 4) If a 4th isotope of beanium, D (green), were added to the pool, how would the average atomic mass change? Mixture of an element and a compound, changing the subscript changes of the compound. 5) Compare your average atomic mass to that group next to you. Why is the number slightly different? Would the difference be larger or smaller sizes were used?
Neon has an atomic number of 10, and a mass of 20.180. Neon has three stable isotopes: neon 20, 21, and 22. These three isotopes comprise 90.92 percent of natural neon, 0.26 percent of natural neon, and 8.82 percent of natural neon, respectively. There are five other isotopes of neon, and they are all
When LiCl is burned the color of the light is an intense red. When BaCl2 is burned the energy is released in packages of light which its color is yellow-green. When BaCl2 is burned the energy is released in packages of light which its color is yellow-green. Data Table 2: Data processing | Metallic Element | Hypothesis | Observation | Sodium ChlorideNaCl | I though that the light of the energy release was going to be red. Because the number of electrons in this compound is no too high in comparison of other compounds.
(c) If you wanted 95 percent of the kernels to pop, what time would you allow? (d) If you wanted 99 percent to pop? A) 2 minutes = 120 seconds z(120) = 120-150)/25= -30/25 = -6/5= -1.2 P(z>-1.2) = 0.1151 B) 3 minutes = 180 seconds z(180) = (180-150)/25=30/25 = 6/5 = 1.2 P(z>1.2) = 0.1151 C) If you want 95% of the kernels to pop, what time would you allow? (.95) = 1.645 x-150 = 25*1.645 x = 41.12 = 150= 191.12 seconds x = 3 minutes and 11.12 seconds D) If you want 99% to pop… (.99) = 2.326 2.326 = (x-150)/25 x = 25* 2.326 + 150 x= 208.16 seconds x = 3 minutes and 28.16 seconds 8.46 A random sample of 10 miniature Tootsie Rolls was taken from a bag. Each piece was weighed on a very accurate scale.
The products have a lower enthalpy than the reactants. III. The products are more energetically stable than the reactants. A. I and II only B. I and III only C. II and III only D. I, II and III (1) 6. The average bond enthalpies for O—O and O==O are 146 and 496 kJ mol−1 respectively.
Results: | | Tension (N) | a (experimental) | a (theoretical) | 0.05 | 0.05 | 0.49 | 0 | 0 | 0.05 | 0.1 | 0.65 | 3.24 | 3.27 | 0.1 | 0.15 | 1.18 | 2.07 | 1.96 | 0.1 | 0.2 | 1.31 | 3.43 | 3.27 | Analysis/Discussion: The results show that the greater the ratio of mass, the acceleration will be also greater. The hypothesis was found to be true. When both masses are the same, the acceleration (both theoretical and experimental) are indeed zero. As the ratio of the masses increased, so did the acceleration. The tension got bigger as the
It was hypothesised that the isolated chloroplasts from silverbeet leaves exposed to while light (Tube 3); the tube wrapped in red cellophane (Tube 6) would have a faster rate of photosynthesis, than the chloroplast kept in the dark (Tube 2), the boiled chloroplast suspension (Tube 4), the addition of DCMU (Tube 5) and the tube wrapped in green cellophane (Tube 7).
