What does the egg represent how about the egg shell drifting continent? The egg could be seen as a tiny model of the Earth. The thin shell represents the Earth’s crust, divided into plates; within the shell is the firm but slippery mantle. Move the pieces of shell around. Pull the plates apart and push […]
Is anyone lost in space?
Is anyone lost in space? A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The two worst disasters both involved NASA’s space shuttle. What are the risks of […]
Does the direction of EMF depend on direction of current?
Does the direction of EMF depend on direction of current? Direction of EMF is decided by the construction of the battery cell, it does not depend upon the direction of the current flow. In fact direction of the current flow depends upon the direction of emf. However direction of the voltage drop depends upon the […]
What happens to the electrons in the anode?
What happens to the electrons in the anode? In electrochemistry, the anode is where oxidation occurs and is the positive polarity contact in an electrolytic cell. At the anode, anions (negative ions) are forced by the electrical potential to react chemically and give off electrons (oxidation) which then flow up and into the driving circuit. […]

How do machines help us in everyday life?
How do machines help us in everyday life? Simple machines make the things in everyday life work. These simple machines are used in more complex devices every day, making tasks much easier. Simple Machines. Simple machines make tasks simpler by reducing the amount of effort it takes for humans to perform certain tasks. What are […]
What is a low center of gravity?
Is stellar parallax true?
Is stellar parallax true? Stellar parallax remains the standard for calibrating other measurement methods (see Cosmic distance ladder). Accurate calculations of distance based on stellar parallax require a measurement of the distance from Earth to the Sun, now known to exquisite accuracy based on radar reflection off the surfaces of planets. What is the cause […]

Common examples of data types Boolean (e.g., True or False) Character (e.g., a) Date (e.g., 03/01/2016) Double (e.g., 1.79769313486232E308) Floating-point number (e.g., 1.234) Integer (e.g., 1234) Long (e.g., 123456789) Short (e.g., 0) […]
What is the variable you change?
What is the variable you change? An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as […]
