How does water affect a magnetic field? Why doesn't Mars have a magnetic field? Why do planets have magnetic fields? Why does Mercury have a magnetic field? Why must soft iron be used with an electromagnet? Why do magnets lose their magnetism when heated?
Magnetic Fields Magnetic fields are known to have an effect on many animals including Monarch Butterflies, lobster, sharks, and birds. These animals are able to detect magnetic fields and use them to alter their direction as needed. Answer and Explanation:1 ...
Dry industrial hemp seed was exposed to static magnetic fields ranging from 65 ± 3 to 505 ± 8 mT for 2 h prior to seed germination. Germination was performed at 13.6 ± 0.7 °C, a temperature that is representative of the germination temperatures of industrial hemp in the U.S. state ...
Water economicsEfficiencyRebound effectComputable general equilibriumGovernments stimulate efficiency measures to save water resources, particularly in areas with high water stress and those that experience droughts. However, economic theory and some empirical studies tell us that the effects of efficiency ...
[69]) is needed, since the local fields and dielectric properties are not well represented by mean values assumed in Fig. 5. 4.2. Asn-221 mutants Similar experiments with strains N221T, H, I, S, P and D have shown dramatic effects on the thermodynamic parameters measured in the presence...
This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour, trap heat from the sun and therefore warm the earth. Without the 'greenhouse effect', the earth would be about thirty-three degrees Celsius cooler than it is. So, we need those gases. ...
Rain or fresh water prevents the deep convection process of the ocean. Deep convection occurs only when the salinity difference between shallow and deep water is small. Although a mere few inches of rain are added to the ocean, such has a great impact because of the ocean's salinity. Thus...
The Mpemba effect is the name given to the assertion that it is quicker to cool water to a given temperature when the initial temperature is higher. This assertion seems counter-intuitive and yet references to the effect go back at least to the writings of Aristotle. Indeed, at first thought...
What effect does adding soap to water have on the surface tension of water?Question:What effect does adding soap to water have on the surface tension of water?Surface tensionWater molecules have the tendency of being attracted to each other. The inward attraction makes water to ap...
