How do you calculate accelerating potential? The kinetic energy of an electron accelerated through a potential difference of V volts is given by the equation: ½ mv2 = eV where e is the electron charge (1.6×10-19 C) [You must be given the electron charge and Planck’s constant in order to answer this question]. What is […]
Which tools should be used to record the most?
Which tools should be used to record the most? Manometer and thermometer are tools that should be used to record the most complete data about a gas. A manometer is an instrument for measuring the pressure of a fluid, consisting of a tube filled with a liquid while a thermometer is a device that measures […]
Why does voltage drop when resistance increases?
Why does voltage drop when resistance increases? Voltage and Resistance are the independent variables, the current is the dependent variable. If you increase the voltage, the current increases proportionally. If you hold the voltage constant but increase the resistance, the current decreases proportionally. What happens to the voltage if resistance increases and current is constant? […]
What are the 10 dimensions of health and wellness?
What are the 10 dimensions of health and wellness? 10 Dimensions of Wellness. Physical. Although some of us may have the flexibility of time while working from home, avoid neglecting our physical wellbeing. Nutrition. It is important to have two to three regular meals a day and not over-eat. Medical and Psychological Health. Social. Environmental. […]
Can we create protons?
Can we create protons? One can obtain a proton by stripping an electron from a hydrogen atom because hydrogen consists of one proton and one electron. This is known as ionization. At Fermilab, we take hydrogen and add an extra electron. This results in negative hydrogen ions. Do protons die? To the best of our […]
Which is stronger alpha helix or beta-sheet?
Which is stronger alpha helix or beta-sheet? Alpha Helix structure of DNA is more stable than Beta pleated Sheet structure. It is stabilized by the regular formation of hydrogen bonds parallel to the axis of the helix; they are formed between the amino and carbonyl groups of every fourth peptide bond. Which is more stable […]
What is adaptive radiation explain with an example?
What is adaptive radiation explain with an example? Adaptive radiation is the relatively fast evolution of many species from a single common ancestor. Adaptive radiation generally occurs when an organism enters a new area and different traits affect its survival. An example of adaptive radiation is the development of mammals after the extinction of dinosaurs. […]
How does an inductor discharge?
How does an inductor discharge? When the current through an inductor is increased, it drops a voltage opposing the direction of current flow, acting as a power load. In this condition, the inductor is said to be discharging, because its store of energy is decreasing as it releases energy from its magnetic field to the […]
Why the Mercator projection is wrong?
Why the Mercator projection is wrong? Mercator maps distort the shape and relative size of continents, particularly near the poles. The popular Mercator projection distorts the relative size of landmasses, exaggerating the size of land near the poles as compared to areas near the equator. Why does Greenland look so big on a map? However, […]
What are the symptoms of depression in the DSM-5?
What are the symptoms of depression in the DSM-5? DSM-5 Criteria for Major Depressive Disorder Depressed mood. Loss of interest/pleasure. Weight loss or gain. Insomnia or hypersomnia. Psychomotor agitation or retardation. Fatigue. Feeling worthless or excessive/inappropriate guilt. Decreased concentration. What is criteria for major depressive disorder? Diminished interest or loss of pleasure in almost all […]
