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 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. […]
What is the difference between salt and sugar dissolving in water?
What is the difference between salt and sugar dissolving in water? The oppositely charged ends of polar water molecules attract the ions and pull them away, resulting in dissolving. Sugar is made from sucrose molecules which are larger and more complex than the ions in salt (See Teacher Background Lesson 1.2). When sugar dissolved in […]
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? 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 […]
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 […]
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 […]
What did Penzias and Wilson discovery prove?
What did Penzias and Wilson discovery prove? Penzias and Wilson had spotted the CMB, the predicted thermal echo of the universe’s explosive birth. The landmark find put the Big Bang theory on solid ground, suggesting that the cosmos did indeed grow from a tiny seed — a single point — about 13.8 billion years ago. […]
