Lead-acid battery

Picture this, you are walking home from a friends house when all of the sudden you are assaulted. Visualize the person who assaulted you. Are they predominately muscular, strong-boned and lean? Is a persons body type even something you would consider when thinking of a reason for the assault? The theory of somatotyping states that a person’s body type is linked to their likelihood of committing a crime or deviant act. Using this theory a connection can be drawn between body type and assault.…

Problem: The research questions being examined in this investigation is, How can we generate electricity by using Potatoes to light an electric bulb? Background Information: How does a potato battery work? The copper (Cu) particles pull in electrons more than the zinc (Zn) molecules. On the off chance that you put a portion of copper and a piece of zinc in contact with each other, numerous electrons go from the zinc to the copper. As they focus on the copper, the electrons repulse each other.…

My research paper is about electrolytes, carbohydrates, and proteins. I am going to be explaining what they are, why we need them, and what are good sources of them. And the big question that I am hoping to solve is why are they so helpful. Why are they so important to the human body. The definition of an electrolyte is “any fluid that conducts electricity, such as this new saltwater solution, is known as an electrolyte solution; the salt ions of which it’s composed are then commonly referred…

In this Duracell ad, it is promoting their batteries. In America, culture staying connected to everyone is important. The underlying fear that one day you might get disconnected is real. Duracell battery’s will help stabilize the fear and give you a backup plan for the unexpected. The ad is selling batteries for everyday use. It is also promoting the long endurance of this specific brand. Beside selling batteries this ad is selling the fear of old toys coming back to haunt us. In the…

Group Experiment Theory Our experiment tests multiple smartphones’ battery life and answers the question of how long do our batteries really last. Since having a smartphone is used as a resource for most of us, it can really affect our everyday lives. Our group wanted to find out the truth about how much battery percentage our apps use on one full charge. One reason we chose this experiment is because the data is accessible to us and easy to track. Additionally, since our group members happen…

DISCUSSION: In this investigation, the effect of electrolyte concentration, depth of electrode immersion in electrolyte, and distance between electrodes in electrolyte, on the current flow through copper electrodes were tested. Table 1 and Graph 1 display the results when increasing electrolyte concentration. Evident in Graph 1, the results contained scatter, and consisted of an outlier in the sample in which the ratio of NaCl: deionised water was 10:30mL. The outlier and scatter may have been…

The solar cell that will be included in the watch will supply enough power to charge the battery on the fitness watch. This enables the fitness tracker to run off solar power and allows the consumer to keep the watch on constantly. Another addition that will be made is incorporating an artificial intelligence (AI), this will interpret the user’s…

Metal electrodeposition is the process of reduction reaction and crystallization of metal ions in an electrolytic cell according to the mechanism of electrolysis. Electrodeposition is one of the main methods for improving and enhancing the metal substrate property. Now, in order to overcome the defect of single electrodeposition with shortcomings of cracks, pores, pits, pocking and so on, the modern new techniques sprang up such as jet electrodeposition [1], ultrasonic vibration assisted…

1M aniline and two different concentration solutions of H2SO4 on a stainless steel substrate. The capacitance properties of polyaniline (PANI) films, have been determined and examined in the selected media of two different concentrations of H2SO4 acid using cyclic volammetry technique. Cyclic voltammetric measurements have shown that PANI films grown by cycling the potential between -0.2V and 1 V in 1M H2SO4 and 2M H2SO4 on SS electrode. The electrochemical characterization of the electrode…

In the passage, “Energy Story”, it explains electricity to the audience by showing how it affects us, and how we depend on it in everyday life. The passage proceeds to explain atoms and what their relationship to electricity is. It continues to talk about electrons and atoms, and describes how within the atoms are electrons, and when the electrons move between the atoms, a current of electricity is created. A description of an experiment the passage used was describing how the chain was similar…
