How can you classify map projections in terms of their distortion characteristics? A common method of classification of map projections is according to distortion characteristics – identifying properties that are preserved or distorted by a projection. The distortion pattern of a projection can be visualized by distortion ellipses, which are known as Tissot’s indicatrices. What […]

Why does the solution conduct electricity when the crystals dissolved in water? When a crystal of an ionic compound dissolves in water, the ions separate. Again, the ions are free to move – so a solution of an ionic compound in water also conducts electricity. Which compound has the most ionic character? The greatest the […]

What can charge an insulator? A conductor is a substance that allows charge to flow freely through its atomic structure. An insulator holds charge within its atomic structure. Objects with like charges repel each other, while those with unlike charges attract each other. What is difference between conduction and induction? In conduction, the neutral body […]

What is the slowest spreading ocean? The Gakkel Mid-Ocean Ridge (MOR) is the slowest spreading center on the planet with full-spreading rates between 1.33 cm/yr along the Greenland end to 0.63 cm/yr along the Siberian end. What is the difference between a fast spread and a slow spread? Steep steps in the seafloor that can […]

How many photos should I take of evidence? three photos What are the three types of photographs taken at a crime scene? To accomplish this, all crime scene photography consists of three basic types of photographs: overall, mid-range, and close-up. What are the four types of photos required at a crime scene? What three types […]

Will 30 minutes of cardio a day burn fat? Researchers found moderately overweight men who exercised hard enough to sweat for 30 minutes a day lost an average of 8 pounds over three months compared to an average weight loss of 6 pounds among men who worked out for 60 minutes a day. The overall […]

Is 1 liter the same as 500ml? One Liter is more than 500 mL since one Liter is equal to 1000 mL. What is 500ml away from 1l? Convert 500 Milliliters to Liters 500 Milliliters (ml) 0.500000 Liters (L) 1 ml = 0.001000 L 1 L = 1,000 ml What is 250ml in cups? Metric […]

How would life in a lake be affected if ice sank and lakes froze from the bottom up? If ice sank, lakes would freeze from the bottom up and the fish and other aquatic creatures wouldn’t survive the winter! Since water is good at holding heat, the more water there is, the more heat it […]

What are the natural variables of Helmholtz free energy? The natural variables are temperature, T, and volume, V . If the temperature and volume are held constant, the system will reach the equilibrium state (pressure, P, and entropy, S) with the minimum Helmholtz free energy. What are the four thermodynamic functions? Four important and useful […]

What are the forces that act between nucleons? Nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. They bind protons and neutrons (“nucleons”) into atomic nuclei. The nuclear force is about 10 millions times stronger than the chemical binding that holds atoms together in […]
