What are the uses of units in our daily life? Measurement provides a standard for every day things and processes. From weight, temperature, length even time is a measurement and it does play a very important role in our lives. The money or currency we use is also a measurement. And think of the rumble […]
Which solid has the highest melting point?
Which solid has the highest melting point? tungsten Do impurities lower melting point? The presence of even a small amount of impurity will lower a compound’s melting point by a few degrees and broaden the melting point temperature range. Because the impurity causes defects in the crystalline lattice, it is easier to overcome the intermolecular […]
How do you analyze graphical data?
How do you analyze graphical data? Data Analysis & Graphs Review your data. Try to look at the results of your experiment with a critical eye. Calculate an average for the different trials of your experiment, if appropriate. Make sure to clearly label all tables and graphs. Place your independent variable on the x-axis of […]
What is needed for an ecosystem to support the greatest variety of organisms?
What is needed for an ecosystem to support the greatest variety of organisms? Answer: An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems require energy from an external source – this is usually the sun. Plants need sunlight to photosynthesize and produce glucose, providing an energy source for other organisms. […]
What is the intensity for muscular endurance?
What is the intensity for muscular endurance? For experienced lifters who want to improve their muscular strength, aim for 8–12 reps per set for 2–4 sets, with a 2- to 3-minute rest between sets. To improve your muscular endurance, do 15–20 repetitions at no more than 50% of your 1RM, with a 2- to 3-minute […]
When two waves interfere destructively what changes?
When two waves interfere destructively what changes? This is known as destructive interference. In fact, if the two waves (with the same amplitude) are shifted by exactly half a wavelength when they merge together, then the crest of one wave will match up perfectly with the trough of the other wave, and they will cancel […]

What is the difference between subduction zones and hot spots?
What is the difference between subduction zones and hot spots? Subduction zones are areas in which oceanic plates are overridden by continental plates, forcing the heavier oceanic crust deep enough to be melted and recycled as second generation magma. Hot spots provide information about the rates and directions of movement of tectonic plates over geologic […]
How big of a telescope do you need to see planets?
How big of a telescope do you need to see planets? Telescopes that have 4 or 5 inch diameters are great for viewing solar system objects like the planets, our Moon, and Jupiter’s moons. Viewing Neptune and Uranus can be difficult with a scope this small but it’s not impossible. A telescope of this size […]
Why gravitation is always attractive?
Why gravitation is always attractive? In the case of gravity, mediated by spin 2 particles, charge is mass, which is always positive. Thus, q1q2 is always greater than zero, and gravity is always attractive. For spin 0 force mediators, however, there is no restriction on the charges and you can very well have repulsive forces. […]
