How gamma rays are used in medicine? Gamma rays are high energy electromagnetic waves which are only stopped by thick lead. This means they can easily pass through medical equipment, such as syringes. As gamma rays pass through the packaging and syringe, they will kill viruses and bacteria which contaminate the syringe. How do doctors […]
When two current-carrying parallel conductors do they attract?
When two current-carrying parallel conductors do they attract? So if you have two current-carrying, parallel wires with magnetic fields circling around them in the same direction, they will attract each other, as shown in the tutorial; at the point at which their respective magnetic fields intersect, they are traveling in opposite directions, and opposites attract. […]
What are the 2 types of comets?
What are the 2 types of comets? There are two categories of comet, based on the amount of time they take to orbit the Sun. Short-period comets take less than 200 years, and long-period comets take over 200 years, with some taking 100,000 to 1 million years to orbit the Sun. What is the difference […]
What are the limitations of descriptive statistics?
What are the limitations of descriptive statistics? Descriptive statistics are limited in so much that they only allow you to make summations about the people or objects that you have actually measured. You cannot use the data you have collected to generalize to other people or objects (i.e., using data from a sample to infer […]

What are three differences between a spreadsheet and a database?
What are three differences between a spreadsheet and a database? Difference between Spreadsheet and Database : Spreadsheet Database It is an interactive computer application for organization, analysis and storage of data in tabular form. It is an organized collection of data generally stored and accessed electronically from a computer system. It stores less data. It […]
What electromagnetic wave is harmful to humans?
What electromagnetic wave is harmful to humans? Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ionizing, and these pose their own special hazards: see radiation poisoning. The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. […]
What are the three steps of inductive reasoning?
What are the three steps of inductive reasoning? Generalizing and Making Conjectures First, observe the figures, looking for similarities and differences. Next, generalize these observations. Then, we form a conjecture. Finally, in some situations, we can apply your conjecture to make a prediction about the next few figures. What are some examples of inductive and […]
What is high Reynolds number?
What is high Reynolds number? The Reynolds number is a dimensionless number. High values of the parameter (on the order of 10 million) indicate that viscous forces are small and the flow is essentially inviscid. What is the problem in Modelling flows with high Reynolds number? The viscous regions in high Reynolds number flows are […]
Can hydrogen be found in the atmosphere?
Can hydrogen be found in the atmosphere? Hydrogen is found in great quantities on Earth combined with other elements, such as in water and hydrocarbons, but it is barely present in our atmosphere, which contains just 0.00005%. Which position of the Earth represents a Solstice? Middle of summer How many minutes of daylight do we […]
