What makes good internal validity? Internal validity is the extent to which a study establishes a trustworthy cause-and-effect relationship between a treatment and an outcome. In short, you can only be confident that your study is internally valid if you can rule out alternative explanations for your findings. What is an example of reliability? The […]
What is it called when a compound breaks apart into its separate elements?
What is it called when a compound breaks apart into its separate elements? Decomposition reaction. A chemical reaction that occurs when a single compound breaks down into two or more elements or new compounds. How will you know if a substance is a compound? If it is pure, the substance is either an element or […]

How does frequency affect loudness?
What are 2 characteristics of covalent compounds?
What are 2 characteristics of covalent compounds? Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds. What is a covalent bond in biology? Covalent bonds, which hold the atoms within an […]
Do cell phones emit ionizing radiation?
Do cell phones emit ionizing radiation? Cell phones emit low levels of non-ionizing radiation when in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy. As stated by the National Cancer Institute, “there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans. […]
What are the 3 stages of water treatment?
What are the 3 stages of water treatment? Wastewater is treated in 3 phases: primary (solid removal), secondary (bacterial decomposition), and tertiary (extra filtration). What are the main points to treat sewage? Primary Treatment In the first of the three steps, the goal is to separate the organic matter and sludge from the rest of […]
Why amplitude is maximum at resonance?
Why amplitude is maximum at resonance? Resonance is the phenomenon that occurs when we force such system to vibrate/oscillate at its natural frequency by a periodic input of some external driving force(i.e; by applying some external force periodically). So this extra energy adds to the amplitude of the system. And the amplitude rises more. What […]
