What increases resistance in a wire? Resistance increases with the temperature of the wire. The hotter wire has a larger resistance because of increased vibration of the atomic lattice. When a material gets hotter the atoms in the lattice vibrate more. What’s the relation between current and resistance? The relationship between current, voltage and resistance […]
Do all elements have isotopes?
Do all elements have isotopes? All elements have isotopes. There are two main types of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes. All artificial (lab-made) isotopes are unstable and therefore radioactive; scientists call them radioisotopes. How do isotopes give off radiation? Radioactive isotope, also called radioisotope, radionuclide, or radioactive nuclide, any […]

How husbands miss their wives?
How husbands miss their wives? Improving your relationship with your husband is the best way to make him genuinely miss you. You can start by considering his point of view instead of focusing only on your own. It’s human nature to think about our own individual needs, but good husbands and wives also think about […]
What is the relationship between transmitted and absorbed light?
What is the relationship between transmitted and absorbed light? The relationship between absorbance and transmittance is illustrated in the following diagram: So, if all the light passes through a solution without any absorption, then absorbance is zero, and percent transmittance is 100%. If all the light is absorbed, then percent transmittance is zero, and absorption […]
What is forward bias?
What is forward bias? Forward biasing means putting a voltage across a diode that allows current to flow easily, while reverse biasing means putting a voltage across a diode in the opposite direction. Why is the base emitter junction forward biased? Forward bias on the emitter to base junction causes the electrons to flow from […]
How do molecules bond with one another quizlet?
How do molecules bond with one another quizlet? A molecule is neutral group of atoms held together by covalent bonds. As atoms near each-other, the charged particles in their valence shells begin to interact. The positive nuclei and the negatively charged electrons in the outer shells are ATTRACTED to one another. What are the two […]
Why is it important to submit assignments on time?
Why is it important to submit assignments on time? Homework provides students with necessary practice in writing, thinking, reading, and problem-solving. Doing homework in time is very important since it will show your professor that you are a serious student who is interested in the subject. If you perform all your tasks on time, this […]
Where did farming begin in the world?
Where did farming begin in the world? The Zagros Mountain range, which lies at the border between Iran and Iraq, was home to some of the world’s earliest farmers. Sometime around 12,000 years ago, our hunter-gatherer ancestors began trying their hand at farming. Where did first farmers come from? Farming is thought to have originated […]
