Why red is more energetic than yellow? Since, red light has lower frequency than yellow, yellow has higher momentum than red, not mass. In a way, it’s the momentum of photons which cause the radiation pressure. If the hotter an object, the brighter it glows (more energy), then why is a blue flame less visible […]
What happens to current If voltage is doubled?
What happens to current If voltage is doubled? if you increase the voltage (or electrical pressure) in a circuit then the current (flow of electrons) will increase in direct proportion, eg if you double the voltage the current flow will double. What if both voltage and resistance are doubled? and if the voltage and the […]
What are the advantages and disadvantages of coal power?
What are the advantages and disadvantages of coal power? Coal energy is an affordable energy source because of the coal’s stable price compared to other fuel sources. Coal is easy to burn. Coal produces high energy upon combustion. Coal energy is inexpensive. Why should we not use coal? In 2012, coal accounted for 37.4% of […]
What is the difference between loudness and frequency?
What is the difference between loudness and frequency? Frequency (the number of vibrations or sound waves per second) is measured in Hertz (Hz). A sound that is 4,000 Hz (like the sound the letter “F” makes) has 4,000 waves per second. Intensity (loudness) is the amount of energy of a vibration, and is measured in […]
How long was the era of nuclei?
How long was the era of nuclei? 380,000 years What did the first Dying stars create? The nucleosynthesis that occurs during the explosion of a supernova produces elements with a higher atomic number than iron, which cannot be created by nuclear fusion. When the first stars died out this way, brand new elements, including gold, […]

There may be a greater chance of chlamydia affecting fertility if you have repeated infections or if it goes untreated and causes a condition called Pelvic Inflammatory Disease […]
What are the three functions of the Golgi apparatus?
What are the three functions of the Golgi apparatus? The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations. As the secretory proteins move through the Golgi apparatus, a number of chemical modifications may transpire. What would happen to the life of cell if there […]
When carbon reacts with a small amount of oxygen?
When carbon reacts with a small amount of oxygen? When carbon is oxidized in a small amount of oxygen, the principle product formed is carbon monoxide (CO), when the oxidation occurs in a higher concentration of oxygen, the principle product formed is carbon dioxide (CO2). What happens when carbon reacts with excess of oxygen? Carbon […]
Can fossils be found anywhere?
Can fossils be found anywhere? For example, many fossils form when plant and animal remains are buried by mud, sand, or soil. This helps to preserve the remains long enough for them to form fossils. Still, fossils can be found just about anywhere. From the tops of mountains to the depths of the seas, fossils […]
