Gravitational constant

idea which is now known as the photoelectric effect; this refers to “...the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light”(McGill). His prediction of the equation, E=hf (energy = Planck’s constant multiplied by the frequency) was tested experimentally and proven to be correct (McGill). This impacted society for years to come because if other scientists wouldn 't have known about it, they wouldn 't have discovered many things that we use…

as RPM increases, height decreases. Experimentally it has been shown that, h=〖Cω〗^(-a) (1) Where h – Final Film Thickness, ω – Spin Speed and C & a are some constants. In this report, Polymer Concentration: The film thickness is inversely proportional to viscosity. Also viscosity is directly proportional to solute concentration. Hence, as the concentration decreases, final film thickness decreases. Concentration…

MT: The scientific method is the best method for determining what the universe around us is and how it works, this is provable based on the amount of evidence science has provided for the claims it has, while other methods rely on “faith” which by definition means you believe something without evidence. BP1: The scientific method has led to the conclusion that based on what we know about the state of the universe today we can demonstrate that the universe must have began with a singularity(a…

Dark matter leaves astronomers and physicists baffled as to what it possibly could be. Scientists design experiments to attempt to figure out what it is, but no one truly knows what composes dark matter. Physicists are so interested in understanding dark matter because it accounts for the formation of the Universe, as observable through studying the distribution of gravity within galaxies (Carnegie). Original attempts at studying dark matter referred to dark matter as baryonic, which is a word…

Even when in a group, participants may experience shifts in attitude and mental sharpness. They may experience a wide range of mental strains from being on a relentless shifting schedule to being confronted with extreme boredom. The constant interaction between whatever crew members are there, and in the case of a solo mission the lack of crew members to talk to can also be a point of stress. This stress has led some astronauts to experience behavioral and cognitive conditions. On top…

Analysis/Discussion: This graph above shows that different heights does affect the speed of a shuttlecock. On the x axis, the data is the height of where the shuttlecock is dropped from, while the y axis is the average speed (m/s). The height where the shuttlecock is dropped increases, as the average speed of each height increases as well. The result of the graph is shown that the line keeps on increasing even if it is not a straight line graph. These results support my hypothesis, which states…

Eggs are the most fragile thing you can find, one drop and they will break. What can we do to protect the egg from breaking when it falls? First, there are many factors that affect the egg when it falls. The factors are momentum, air resistance, pressure, gravity, and angular momentum. The first factor is Momentum; it is the product of the mass and velocity of an object. “P” is the 3D vector stating the object’s momentum in 3 directions of 3D space. Where “V” is the 3D velocity vector giving the…

reservoir is usually a glassware or reagent bottle which contained the analytic sample. It is located at the upper part of the HPLC. It is also known as mobile phase reservoir since the sample will be moved. The flowing of the sample is depends on gravitational pull. The solvent which needed to be analysed is a liquid which consisted of polar and non-polar components and the concentration of respective components is depends on the contents of the sample used. There are some requirements need to…

Acceleration, velocity, and gravity are important concepts that each played a role in this lab. Velocity is defined as the speed and direction of motion of a given object. The equation for this particular concept is: v=d/t which states that velocity equals displacement in respect to time. Acceleration is defined as how quickly and in what direction velocity changes. The equation for acceleration is: a=∆v/∆t in which the variable a represents acceleration, ∆v represents the change in velocity,…

If the mass of an object is held constant, increasing force will increase acceleration. If the force on an object remains constant, increasing mass will decrease acceleration” (How Newton’s Laws of Motion Work). Newton equated forces so that he could differentiate the change in momentum per unit time. Momentum is a characteristic involving…
