The purpose/question that needs to be answered is why is the lamp not working.

A reasonable hypothesis would be that the light bulb is burned out. The experiment would be to change the light bulb (with a new one) and turn on the lamp to see if the lamp turns on. For data, one would just observe if the light comes on or not. This type of problem does not lend itself to being graphed. There are no measurements that need to be taken. The data can be observed by turning on and off the lamp to see if the problem has been fixed. The dependent variable is the lamp (whether it lights ...

The USA today is one of the oldest news sources in America. The paper operates as a flagship operation of its parent company Gannett Company. It was in late 1982 and is currently being printed at thirty-seven different site across the United States. The paper has five additional printing stations internationally where it prints its international papers. The paper has managed to stand out through the use of a dynamic design that stands out from other newspapers. USA Today uses concise reporting coupled with colourized images and graphics to pass its information to its readers. The newspaper combines America’ ...

If a fuel mixture can be represented by the general formula CxH2x, prove that the stoichiometric gravimetric air/fuel ratio is 14.8:1.

The combustion reaction for a given fuel mixture will look as follows:

CxH2x + 1.5x(O2 + 3.76N2) → xCO2 + xH2O + 1.5x*3.76N2 The molar ratio is 1.5x:1, to find the gravimetric ratio, the masses of the air and fuel should be found. This can be done by multiplying molar ratio with molar weights of the fuel and air. m(fuel) = 12*x + 2x*1 = 14x m(air) = 1.5x(16*2 + 3.76*14*2) = 1.5x*137.28 = 205.92x The gravimetric stoichiometric air/fuel ratio then is 205.92x:14x = 14.71:1 The dry exhaust gas analysis from an ...

Q1. Explain the regulation of the cell cycle

Every cell is regulated by particular checkpoints to ensure that the daughter cells are exact duplications. This is to help guarantee that cell mutations are not passed on to the next generation of cells. In eukaryotic cells, there are three main checkpoints. These are points at which cell replication can be halted until certain conditions are met (Boundless, 2016). The first checkpoint is near the end of the G1 phase. It is here that DNA gets evaluated and checked for damage. If damage has occurred, it either gets corrected or gets prevented from moving on to the next phase ( ...

When an oocyte and spermatozoa fuse, the process is referred to as fertilization. The gametes are haploid at that stage and grow further into a diploid zygote. There is a difference in the forms that the process can be made possible. It can be through the natural mode that occurs in vitro or can happen outside the body in vivo (Hill, 2016). Research studies have been done adequately to ensure that circumstances that support life out of the womb can be created for a while before a transfer is done to the womb for future growth and development. For ...

A Supernova is typically the resultant of the explosion of a star. It occurs when a there is a change in the core or the center of a star. Supernovas burn only for s short period of time, but they enable scientists to discover many things about the universe. For instance, a kind of supernova has led them to discover that the universe is constantly expanding and growing and that too, exponentially. They also help to distribute elements all around the universe. It so happens that if a star explodes it throws out debris and star’s elements all ...
