Two-dimensional waves are waves that have the ability to travel in more than one dimension. Such waves are those that can travel around corners. Examples of two-dimensional waves are sound waves and water waves. Two-dimensional waves can be illustrated on a ripple tank, which is a glass-bottomed water tank. Dark...

Heat is one of the most important concepts of thermodynamics. Heat concept is very closely related to work concept. Heat and work are both forms of transfer of energy. The difference between heat and work is that they are different forms of energy transfer. Heat is associated with direct contact...

Hydroelectric power is a clean source of renewable energy. This beneficial power source has been utilized in developed nations such as the US for many decades but its potential has not been fully realized in third-world countries. Due to its relatively low operating expense, local farm irrigation, flood prevention and...

The following characteristics should be followed to resolve the trilemma: 1) no competition with food crops and not causing land clearing, 2) reduction of the greenhouse effect and 3) no environmental pollution biofuel production technology (Tilman et al. 2009). Such solutions would help to exclude interference of crops with biofuel,...

Ohm law is attributed to a German physicist known as George Ohm who ascertained the relationship within any DC electrical circuit that exists between current, resistance, and voltage. In electrical engineering, the relationship in Ohm’s law states that, the potential difference in any ideal conductor must be proportional to the...

Ohm’s law was developed in 1827 stating that “the current flowing through a conductor is directly proportional to the potential difference across its ends” (Sardar 90). In other words, the current that flows through a conductor at constant temperature is directly proportional to the potential difference across the ends of...

Theory In order to achieve static equilibrium, various conditions have to be met. Among these conditions are the resultant force and its angle of application. Therefore this experiment intends to examine and investigate these factors and conditions necessary for the static equilibrium. According to Newton’s first law, the static equilibrium...

Essence The purpose of the linear motion lab experiment was to analyze the graphical relationship of position and velocity with respect to time. Therefore, in order to meet this purpose, this lab employs a motion detector or sensor which uses pulses to detect the position of an object relative to...

1) Define “centripetal force”. How is it related to “centrifugal force”? Centripetal force is the force that keeps objects moving at a uniform speed along a circular path. This is directed along a circle's radius, towards the center of the circle away from the object. Centrifugal force is the lack...

Question One The equation derived in the lab manual is hereby recalled as; a=(F_M-F_m)/(M+m) =(Mg-mg)/(M+m) =[(M-m)/(M+m)]g Therefore to determine whether this equation makes sense, we will equate each of the masses to zero. Experimentally, when one mass is equated to zero, say, by removing all the pennies in one mass,...

Isaac Newton first published his Universal Law of Gravity in the journal, Philosophiæ Naturalis Principia Mathematica, in July of 1687. The story goes that one day, Newton was sitting underneath an apple tree when an apple suddenly fell to the ground. He considered the problem with this, wanting to understand...
