(Nitrogen, hydrogen, oxygen, carbon dioxide, and other elements cause weld defects if introduced to the weld pool.) After a while it was discovered that argon has some advantages over helium. Because argon is heavier than helium, less flow rate is needed. The lower flow rate requirement makes argon better for flat welding. Helium is good for overhead, because it is lighter and thus flows upward.
The relationship between Hamstring strength index 60 degree/s and the Shuttle run test is a negative relationship due to r moves away from zero in negative direction and r = −0.149, the strength of this negative relationships would be weak with r -0.5 r=-0.528**, is more significant since p =0.002< 0.01, where r = −0.498** is significant at p =0.004< 0.01. The smaller the p-value in a test of hypothesis the more significant the results are. 8. The researchers stated that the study showed a positive, significant correlation between Quadriceps strength indices and pre- and postoperative functional stability Considering the data presented in the Table 5, do you agree with their statement? Provide a rationale for your answer.
Answer: I think that the plastic ball will be a lot lighter than the steel and golf ball, so that means that the plastic ball will not have as much effect when hitting the bottom of the cup as the golf or steel ball. I think the heavier ball will make the cup go back further because I think the heavier ball will pick up momentum quicker which will make the ball go faster which will make the ball hit the bottom of the cup at more force so it will move the cup further back.

Which wood burns the fastest? In my research I found that because of the lower density of soft woods they burn more quickly than hard woods. When looking for a fast burning wood, I found most sources recommend using soft wood. I also found that the more resin (also referred to as sap) types of wood contain affects how it burns. The combination of high resin content and low density means easy ignition and a lesser burn time.
If true stress is plotted against true strain, the rate of strain hardening tends to become almost uniform, that is, the curve becomes almost a straight line [2]. The strain hardening coefficient of work is defined as the gradient of the straight part of the line. This is closely related to the shear modulus [2]. Therefore, a metal with a high shear modulus will have a high strain or work hardening coefficient. Grain size will also influence strain hardening, and a material with small grain size will strain harden more rapidly than the same material with a larger grain size.
Even though the results under hexane and toluene are similar, the distances of original mixture, first and second fraction are different from hexane and toluene solvent because they have different polarity. As first fraction containing fluorene, which is much non-polar than fluoreone, fluorene in first fraction is much easier to carry by the moving non-polar solvent. Thurs, as the more non-polar the solvent is the longer distance that fluorene will move. Since hexane has larger non-polar carbon-hydrogen single bond groups than toluene, it is much non-polar than toluene. As the result of this, it can explain why the distance of fluorine in hexane is longer (1.3 cm) than the one in toluene (0.5 cm) and due to less non polar toluene has.
Fiber In the comparison between fiber and copper fiber, costs of the fiber cable has come down quite a bit. The cable itself has become easier to install as well since the invention of the flexible fiber which makes it easier to pull the cable through places. The flexible fiber has not become widely used vs. copper yet due to the need for the costs to come down for the connections, the NIC’s. the hub’s, routers and switches. Fiber Advantages The following advantages of fiber over other cabling systems are: (Oliviero 250) Immunity to electromagnetic interference (EMI), higher data rates, longer maximum distances, and better security.
For example, I always try to but Scotty’s toilet paper over other brands because I love the quality and it lasts longer than generic brands. 2. The Law of Supply-The relationship between price and quantity supplied, called the law of supply which can be summarized as follows: “At higher prices, a larger quantity will generally be supplied than at lower prices, all other things held constant. At lower prices, a smaller quantity will generally be supplied than at higher prices, all other things held constant (Miller, 2012, p.58). I’ve noticed that when items go on sale, they go faster than normal, and when it’s gone that’s it.
Therefore the two kinds of fatty acids compete for same enzyme complex; however, monounsaturated fatty acids are formed in greater concentration than VLCSFA. The reduction in the elongation of VLCSFA and a diet low in VLCSFA will slow the demyelination
Puropose The purpose of this experiment is to see whether breaking the alka- seltzer into smaller pieces will decrease the time of making the canister cap pop. Hypothesis My theory about this experiment is that the more we break the reactant which in this case is the alka- seltzer into smaller pieces and then putting it to water will decrease the time it takes to pop the canister cap. This is because of the more we break something into smaller pieces the surface area increases causing more molecules to become available for collision.
