What is the relation between CP CV and R? where cp is the specific heat coefficient at constant pressure, cv is the the specific heat coefficient at constant volume, gamma is the ratio of specific heats, and R is the gas constant from the equation of state. Is gamma CP a CV? gamma = cp […]
How accurate is a spectrophotometer?
How accurate is a spectrophotometer? The minimum is not sharp and good results can be expected in a transmittance range from 0.2 to 0.6 or an absorbance range from 0.7 to 0.2. An inspection of the graph below indicates that transmittance values of 0.1 and 0.8 are the outside limits between which one can expect […]
Is a Van de Graaff generator dangerous?
Is a Van de Graaff generator dangerous? Preliminary cautions: The Van de Graaff can produce a spark that is simply irritating or quite dangerous. A spark several centimeters long can be the equivalent of 100 000 volts or more. What is the principle of the Van de Graaff generator? The Van De Graaff generator works […]
What is the law of electric charges?
What is the law of electric charges? Things that have the same charge push each other away (they repel each other). This is called the Law of Charges. Things that have more electrons than protons are negatively charged, while things with fewer electrons than protons are positively charged. Things with the same charge repel each […]
How do you do apparent weight?
How do you do apparent weight? The apparent weight of an accelerating object is the vector sum of its real weight and the negative of all the forces that produce the object’s acceleration a = dv/dt. wapparent = wreal – ma. How do you use apparent in a sentence? Certain problems were apparent from the […]

These include, but are not limited to, Protein Energy Malnutrition, Scurvy, Rickets, Beriberi, Hypocalcemia, Osteomalacia, Vitamin K Deficiency, Pellagra, Xerophthalmia, and Iron Deficiency. How do you know if your body is lacking vitamins? 8 Common Signs You’re Deficient in Vitamins […]
What is the relationship between light and photography?
What is the relationship between light and photography? The relationship between the light, the subject and the viewer is at the heart of Lighting. The photographic subject can transmit, absorb or reflect photons (light particles). What is light and why it is important to photography? Lighting is a key factor in creating a successful image. […]
Are Push Ups anaerobic?
Are Push Ups anaerobic? Aerobic exercise (also known as cardiovascular exercise) builds your endurance. Anaerobic exercise typically means activities such as weightlifting and push-ups and sit-ups, which builds muscle and physical strength through short bursts of strenuous activity. Is speed aerobic or anaerobic? In most forms of speed training, including sprinting on the track or […]
What is a experiment simple definition?
What is a experiment simple definition? An experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Uses of experiments vary considerably between the natural and human sciences. What is basic experiment? A simple experiment is […]
What is the electric flux through a cube of 1 cm?
What is the electric flux through a cube of 1 cm? Therefore, the net charge enclosed within the cube is zero. Therefore, electric flux is zero. What are the three basic properties of the electric charge? In this section, we will learn about three such properties of point charges; the additivity of electric charge, the […]
