What do you include when you communicate your results? It is important to share what you have learned with others. Scientists often find solutions to problems by knowing the results of other scientists’ experiments. Communicating your results is often the first step to clearly identifying a problem and beginning to think about possible solutions. How […]

How long will a capacitor last?
How long will a capacitor last? Capacitors have a limited life span. Most are designed to last approximately 20 years, but a number of factors can cause them to wear out quicker. How fast does a capacitor charge without a resistor? After 5 time periods, a capacitor charges up to over 99% of its supply […]
Do we live in a binary star system?
Do we live in a binary star system? For some time now, astronomers have known that the majority of systems in our galaxy consist of binary pairs rather than individual stars. What’s more, in recent decades, research has revealed that stars like our Sun are actually born in clusters within solar nebulas. What happens when […]
Which number is written correctly in scientific notation?
Which number is written correctly in scientific notation? Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8. […]
What is the coldest metal in the world?
What is the coldest metal in the world? Gadolinium What is the warmest metal? By zapping a piece of aluminum with the world’s most powerful x-ray laser, physicists have heated matter to 3.6 million degrees Fahrenheit (2 million degrees Celsius)—making it briefly the hottest thing on Earth. What is the most hottest thing on earth? […]
How do you calculate the length of a wire?
How do you calculate the length of a wire? To calculate spring wire length per coil, you must subtract the wire diameter from the outer diameter in order to get mean diameter. Once you have calculated mean diameter, multiply it by pi (3.14); this will give you the length of wire per coil. How do […]

What is an S3 gallop?
What is an S3 gallop? The third heart sound (S3), also known as the “ventricular gallop,” occurs just after S2 when the mitral valve opens, allowing passive filling of the left ventricle. A S3 can be a normal finding in children, pregnant females and well-trained athletes; however, a S4 heart sound is almost always abnormal. […]
