Does light travel faster in glass than in water? In water, the refractive index is 1.3 and in glass, it is 1.5. Therefore, light travels faster through water, than it travels through glass. Why does light pass through glass? Photons pass through glass because they are not absorbed. And they are not absorbed because there […]
Is energy released when two hydrogen atoms form a covalent bond?
Is energy released when two hydrogen atoms form a covalent bond? The amount of energy released when the bond is formed is called the bond energy. Formation of a covalent bond releases the bond energy, which means that as the bond forms, the energy of the atom decreases. In the diagram below you can see […]
Can 0 degrees freeze water?
Can 0 degrees freeze water? We’ve all been taught that water freezes at 32 degrees Fahrenheit, 0 degrees Celsius, 273.15 Kelvin. Scientists have found liquid water as cold as -40 degrees F in clouds and even cooled water down to -42 degrees F in the lab. How cold is hot ice? Although it looks like […]
Do transistors amplify voltage?
Do transistors amplify voltage? A transistor can amplify current and it can amplify voltage and it can do BOTH at the same time. A transistor can also amplify the voltage is “sees” on the base. It does this in common-emitter mode where the emitter is connected to the 0v rail and the collector has a […]
What happens to extra electrons in a charged object when it becomes grounded?
What happens to extra electrons in a charged object when it becomes grounded? Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer of […]
Will the next force be equal to zero?
What are the components of centripetal force?
What are the components of centripetal force? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the centripetal force […]
Do not use your horn directly behind a or a horse rider on the side of the road?
What was the most important finding of the Miller-Urey experiment?
What was the most important finding of the Miller-Urey experiment? Careful analysis revealed that through a series of reactions, many complex molecules had been produced. Among these were amino acids – special molecules of life that we once thought could only be built inside the bodies of living creatures. This was a pivotal breakthrough in […]
Are Airboats noisy?
Are Airboats noisy? But according to the preliminary draft of the scientific study, even an airboat fitted with a muffler exceeds 90 decibels at open throttle. The reason is that as power increases, the propeller makes more noise than the motor. “I think everybody understands there has to be some kind of muffling system,” Huffman […]
