Can a valid argument have a false conclusion? So it is possible for a valid argument to have a false conclusion as long as at least one premise is false. A sound argument really does have all true premises so it does actually follow that its conclusion must be true. 3. If a valid argument […]
Are Diamonds cleave smoothly?
Are Diamonds cleave smoothly? Even though diamond is the hardest natural material, it can chip and fracture in the course of normal wear. Diamond is formed in the cubic crystal system and has four perfect cleavage directions. A cleavage plane is the weakest direction in the molecular arrangement of the crystal. Do diamonds block radiation? […]
Do astronomers use reflecting or refracting telescopes?
Do astronomers use reflecting or refracting telescopes? A refractor uses lenses within a tube to refract (bend) light. It’s the type of long telescope which you might imagine old-time astronomers, like Galileo, using. Reflectors, on the other hand, use mirrors instead of lenses to reflect light. Most modern observatories use reflectors because their telescopes are […]

Why do we need controls?
Why do we need controls? Controls allow the experimenter to minimize the effects of factors other than the one being tested. It’s how we know an experiment is testing the thing it claims to be testing. This goes beyond science — controls are necessary for any sort of experimental testing, no matter the subject area. […]

Is 2h2 O2 2h20 a balanced equation? Yes, the equation is balanced. There are the same number of Hydrogen (H) and Oxygen (O) atoms on both sides of the equation. What is the balanced equation for ammonia and oxygen? NH3+O2–>NO+ H2O. Which element should you balance last? hydrogen How do you read a balanced chemical […]
How far back can carbon dating date?
How far back can carbon dating date? C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to approximately 50,000 years ago, although special preparation methods occasionally make accurate analysis of older samples possible. […]
What is the function of non striated muscle tissue?
What is the function of non striated muscle tissue? Smooth Muscle Tissue is also known as non-striated muscle or involuntary muscles controlled by the Autonomous Nervous System. Functions of non-striated muscle: It stimulates the contractility of the digestive, urinary, reproductive systems, blood vessels, and airways. What is the main function of striated muscle? Striated muscles […]
What does an alpha level of .05 mean?
What does an alpha level of .05 mean? What Is the Significance Level (Alpha)? The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is […]
What is the angle between electric field and dipole moment at an equatorial point?
What is the angle between electric field and dipole moment at an equatorial point? What is the angle between the electric dipole moment and the electric field on the equatorial line of the dipole? On equatorial line, the direction of electric field is reversed to that of angle of axial line. Therefore, the angle between […]
