What are three common indicators? The three most common indicators are: Litmus, Methyl orange and Phenolphthalein. What are the two types of indicators? Type of indicators Input indicators. These indicators refer to the resources needed for the implementation of an activity or intervention. Process and output indicators. Process indicators refer to indicators to measure whether […]
What is the RMS voltage of the source?
What is the RMS voltage of the source? The root-mean-square (rms) voltage of a sinusoidal source of electromotive force (Vrms) is used to characterize the source. It is the square root of the time average of the voltage squared. The value of Vrms is V0/Square root of√2, or, equivalently, 0.707V0. Why we use RMS voltage? […]
What is the main cause of climate change?
What is the main cause of climate change? Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”. Are cars or cows worse for […]
How do we see distant galaxies?
How do we see distant galaxies? The most distant galaxies are caught up in the expansion of the Universe, causing distant galaxies to redshift past the point where our optical and near-infrared telescopes (like Hubble) could detect them. Finite sizes and observing times meant that only the galaxies above a certain brightness threshold could be […]
What happens if a consumer is removed from a food web?
What happens if a consumer is removed from a food web? If we remove any one level from the food web, all the other levels are automatically affected. For example, if we remove the consumers, producers will have no predator and hence will grow unchecked, while any higher level consumer dependent upon these consumers will […]
Where is uranium found naturally?
Where is uranium found naturally? Uranium is found in small amounts in most rocks, and even in seawater. Uranium mines operate in many countries, but more than 85% of uranium is produced in six countries: Kazakhstan, Canada, Australia, Namibia, Niger, and Russia. Is it illegal to build a nuclear bomb? Law or no law, rights […]
What happens to pressure and volume when temperature decreases?
What happens to pressure and volume when temperature decreases? when the temperature of a gas at constant pressure is increased. its volume increases. when the temperature of a gas at constant pressure is decreased, its volume decreases. when the pressure is decreased, the volume increases. How long does a gas pressure test take? 15 minutes […]
What cars will survive an EMP?
What cars will survive an EMP? Most cars will survive an EMP attack, but the vehicle that is most likely to survive is an older model diesel vehicle with minimal electronics. For a surefire way to shield from EMP, building a faraday cage garage for your car would be a useful project. Is it illegal […]
What are the values of good scientist?
What are the values of good scientist? Those surveyed, using a scale from zero to ten, were asked to rate attentiveness, collaborative, courage, curiosity, honesty, humility to evidence, meticulousness, objectivity, perseverance and skepticism with regard to their importance for scientific research. What are the values of attitude? Dissimilarities between Values and Attitudes Values Attitudes Values […]
Is list comprehension faster than for loop?
Is list comprehension faster than for loop? List comprehensions are often not only more readable but also faster than using “for loops.” They can simplify your code, but if you put too much logic inside, they will instead become harder to read and understand. When should you use a function instead of a loop? “Use […]
