What is effect of intensity of light? Intensity cannot change the cut off frequency or stopping potential. High intensity means more number of photons, so chances of hitting to electron by them increase and hence more photo electron are emitted i.e., photo current increases. Why intensity decreases as distance from the light source increases this […]
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 […]
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 […]
Can electrons exist alone?
Can electrons exist alone? Electrons have mass, charge, angular momentum, an intrinsic magnetic moment and helicity, but they have no known substructure. No two electrons can occupy the same space at the same time. They are part of every atom but they can exist separately on their own as well. What happens to the atoms […]
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, […]
What would happen if temperature and precipitation changed in a climate zone?
What would happen if temperature and precipitation changed in a climate zone? Changes in temperature and precipitation can disrupt a wide range of natural processes, particularly if these changes occur more quickly than plant and animal species can adapt. In response, average temperatures at the Earth’s surface are rising and are expected to continue rising. […]
Can you differentiate tangential velocity and tangential acceleration?
Can you differentiate tangential velocity and tangential acceleration? If the tangential velocity is not changing directions, then the object is not moving in a circle. Tangential acceleration results from the change in magnitude of the tangential velocity of an object. An object can move in a circle and not have any tangential acceleration. How do […]
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 […]
Does it matter where you put the dots on a Lewis structure?
Does it matter where you put the dots on a Lewis structure? In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, a simple way of representing those valence electrons would be useful. Again, it does not matter on which sides […]
Had chlamydia for 2 years can I still get pregnant?
Had chlamydia for 2 years can I still get pregnant? Most women who have had chlamydia won’t have any difficulties conceiving that are related to the infection. 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 […]
