What is the difference between rising and sinking air? Rising air always cools, and, conversely, sinking air always warms. This type of temperature change, which is caused simply by ascent or descent in the atmosphere, is called adiabatic cooling or warming. When air moves vertically, its pressure changes. What is the diff between climate and […]

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 […]

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. […]

What is the relation between frequency and wavenumber? Frequency is a measurement of the number of wave cycles per second. Wavenumber is the reciprocal of the wavelength multiplied by a constant. Although they look the same, the difference is that wavenumber has nothing to do with the velocity of the wave- wavenumber is measured in […]

What is the hottest country in the world? Djibouti How hot is 40 degrees in Australia? In Central Australia, we find extreme temperatures sometimes it may reach up to 50 degrees and cannot see rains for years….Air Temperature. Degree Centigrade Degree Fahrenheit 31 88 35 95 38 100 40 105 Is Australia the hottest place […]

Is any closed conducting path? There must be a closed conducting loop from the positive to the negative terminal in order to establish a circuit and to have a current. When this occurs, the circuit is opened and a closed conducting loop no longer exists. Without a closed conducting loop, there can be no circuit, […]

What will JB Weld not stick to? When fully cured, J-B Weld is completely resistant to water, gasoline, and about every other petroleum product or automotive chemical. For wet-surface or submerged water or gasoline repairs, try our SteelStik or WaterWeld. How long will JB Weld last? CURE AND SET TIME: After mixing the tubes at […]

What is the ultimate original source of energy? The sun Is soil considered a living thing? The job of the organisms is to keep the soil healthy. carbon and mineral matter in the soil, and painting with soil. Soil is a living thing – it is very slowly moving, changing and growing all the time. […]

What is currently the most popular trait theory of personality? Trait theorists attempt to explain our personality by identifying our stable characteristics and ways of behaving. The Five Factor Model is the most widely accepted trait theory today. The five factors are openness, conscientiousness, extroversion, agreeableness, and neuroticism. These traits occur along a continuum. Is […]

Why are light bulbs brighter in a parallel circuit? When the bulbs are in parallel, each bulb sees the full voltage V so P=V2R. Since a bulb glows brighter when it gets more power the ones in parallel will glow brighter. See, the parallel combination of resistors reduces the effective resistance of the circuit. Hence […]
