For which object would a geologist use carbon 14 dating to determine age? The correct answer is – the first object, the animal skull. The radiocarbon dating, also referred to as carbon -14 dating, is used for the determining of the age of an object containing organic matter based on the properties of the radiocarbon. […]
Why does a rocket keep accelerating?
Why does a rocket keep accelerating? As the rocket velocity increases, it encounters air resistance, or aerodynamic drag, which opposes the motion. Drag increases as the square of the velocity. The thrust of the rocket must be greater than the weight plus the drag for the rocket to continue accelerating. Do Newton’s laws apply in […]
Why do electrons do not fall in nucleus?
Why do electrons do not fall in nucleus? Quantum mechanics states that among all the possible energy levels an electron can sit in the presence of a nucleus, there is one, which has THE MINIMAL energy. This energy level is called the ground state. So, even if atoms are in a very very called environment, […]
What are the three types of pain receptors?
What are the three types of pain receptors? Within the central nervous system, there are three types of opioid receptors which regulate the neurotransmission of pain signals. These receptors are called mu, delta, and kappa opioid receptors. What are the two types of pain fibers? Each of the spinal nerves emerging from the spinal cord […]
What is another word for isotope?
What is another word for isotope? What is another word for isotope? element form variant version What is the correct statement about isotopes? Isotopes of only heavier elements are radioactive in nature as they have large difference in the number of protons and neutrons. Thus, we can conclude that the statement isotopes of the same […]
How do you fight a polar bear?
How do you survive freezing temperature without heat?
How do you survive freezing temperature without heat? Here are a few tips to stay warm and happy this winter with no heat: Reduce as much heat loss as possible. Put blankets over all the windows and outside doors, and bean bag draft busters at the base of every door. Adding Insulation Supercharges Your Walls. […]
How do you protect a Mosfet from a short circuit?
How do you protect a Mosfet from a short circuit? The voltage across the internal resistance can be sensed using simple comparator or even a transistor, which switches on at a voltage of around 0.5V. You can thus avoid the use of a sense resistor (shunt), which usually produces an undesirable extra voltage drop. The […]
What are the rules for a series circuit?
What are the rules for a series circuit? In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a […]
