What should your CO2 level be? Test results. The normal range for CO2 is 23 to 29 mEq/L (milliequivalent units per liter of blood). The blood test often measures blood pH along with CO2 levels to further determine the cause of your symptoms. Blood pH is a measurement of acidity or alkalinity. What percentage of […]
What are the main differences between the Thomson and Rutherford models?
What are the main differences between the Thomson and Rutherford models? The main difference between Thomson and Rutherford model of atom is that Thomson model does not give details about the atomic nucleus whereas Rutherford model explains about the nucleus. What is the difference between Rutherford and Bohr model? The main difference between Rutherford model […]
What is the parallax of error and how could we avoid it?
Which device is used to indicate the direction of current?
Which device is used to indicate the direction of current? The current flows through the ammeter. Note that an ammeter has a very low resistance. How can a DMM be used to determine the direction of flow? When using a multimeter to measure current, the only way that can be used to detect the level […]
What is the minimum ceiling for VFR flight?
What is the minimum ceiling for VFR flight? IFR means a ceiling less than 1,000 feet AGL and/or visibility less than three miles. Low IFR (LIFR) is a sub-category of IFR. VFR means a ceiling greater than 3,000 feet AGL and visibility greater than five miles. What is the minimum VFR? Basic VFR Weather Minimums […]
Why did HAL 9000 go crazy?
Why did HAL 9000 go crazy? Dr. Chandra discovers that HAL’s crisis was caused by a programming contradiction: he was constructed for “the accurate processing of information without distortion or concealment”, yet his orders, directly from Dr. What is the point of the monolith in 2001? The Monolith in the movie seems to represent and […]
What are physical and human features?
What are physical and human features? Places are jointly characterized by their physical and human properties. Their physical characteristics include landforms, climate, soils, and hydrology. Things such as language, religion, political systems, economic systems, and population distribution are examples of human characteristics. Who is the father of physical geography? Eratosthenes Why is physical geography important […]
What is the point estimate formula?
What is the point estimate formula? Once you know these values, you can start calculating the point estimate according to the following equations: Maximum Likelihood Estimation: MLE = S / T. Laplace Estimation: Laplace = (S + 1) / (T + 2) Jeffrey Estimation: Jeffrey = (S + 0.5) / (T + 1) What is […]
Can Atom survive without electron?
Can Atom survive without electron? Electrically neutral atoms can exist with no electrons. So an atom can’t have no electrons as it, by definition has protons and to be neutral must have electrons. You can have an ion, such as a hydrogen ion (you might call it a proton). What would happen if an atom […]
Do vaccines come from cows?
Do vaccines come from cows? The word “vaccination”, coined by Jenner in 1796, is derived from the Latin adjective vaccinus, meaning “of or from the cow”. Once vaccinated, a patient develops antibodies that make them immune to cowpox, but they also develop immunity to the smallpox virus, or Variola virus….Cowpox. Cowpox virus Species: Cowpox virus […]
