How do you set up dimensional analysis problems? Set up each problem by writing down what you need to find with a question mark. Then set it equal to the information that you are given. The problem is solved by multiplying the given data and its units by the appropriate unit factors so that only […]
Is Ursa Minor the North Star?
Is Ursa Minor the North Star? Ursa Minor, though, is almost entirely represented by the Little Dipper. The most famous star in the Little Dipper is Polaris, which is currently known as the North Star or Pole Star, as it appears to be aligned with Earth’s axis, or Celestial Pole. How do you identify Ursa […]
How many red blood cells and white blood cells are in a single drop of blood?
Can two persons have same voice?
Can two persons have same voice? Although some people might sound quite a bit alike, no two voices are ever exactly alike. We each have a unique voice because so many factors work together to produce that voice. The pitch of your voice is largely determined by the length and tension of your vocal cords. […]
How does photon interact with matter?
How does photon interact with matter? Photons interact differently in matter than charged particles because photons have no electrical charge. give up their energy via secondary interactions (mostly ionization). The interaction of photons with matter is probabilistic, while the interaction of charged particles is certain. What happens if an incident photon collides with a moving […]
Are there any full blooded aboriginal peoples left 2020?
Are there any full blooded aboriginal peoples left 2020? Yes there are still some although not many. They are almost extinct. There are 5000 of them left. There are 468000 Aboriginals in total in Australia in which 99 percent of them are mixed blooded and 1 percent of them are full blooded. What is wrong […]
Is current directly proportional to voltage?
Is current directly proportional to voltage? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is relation between voltage and current? […]
What factors influence potential and kinetic energy?
What factors influence potential and kinetic energy? Since the state of motion of an object can change with time, the kinetic energy of an object can also change with time. The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to […]
What is the use of Natrium 24?
What is the use of Natrium 24? Sodium 24 is used as an electrolyte tracer to follow the path sodium takes in a person’s body to see if their uptake levels are within normal ranges, while sodium 22 is used in nuclear medicine imaging for positron emission tomography. Sodium -24 can also be used in […]
What is difference between paramagnetic and diamagnetic?
What is difference between paramagnetic and diamagnetic? Atoms with all diamagnetic electrons are called diamagnetic atoms. A paramagnetic electron is an unpaired electron. Diamagnetic atoms repel magnetic fields. The unpaired electrons of paramagnetic atoms realign in response to external magnetic fields and are therefore attracted. Why zinc is diamagnetic? Answer. Answer: Diamagnetic means the orbitals […]
