Which force is most important in tug of war? The normal force is the force with which the two surfaces are pushed together. In the case of this simple tug of war above, the ground pushes up with a force equal to the gravitational weight of the person. This means that heavier people will have […]
What is the difference between sea surface temperature and hurricane strength?
What is the difference between sea surface temperature and hurricane strength? Development of a tropical depression into a mature hurricane requires heat energy from the ocean surface. For this reason, hurricanes do not usually develop over land or outside of the warm tropical oceans where the sea surface temperature (SST) is colder than ~26.5°C (~80°F). […]
Which process is involved when the oceanic crust plunges down into the mantle?
Which process is involved when the oceanic crust plunges down into the mantle? subduction What happens to old oceanic crust as new molten material rises from the mantle? What happens to old oceanic crust as new molten material rises from the mantle? It is recycled back into the mantle through the process of subduction. The […]
What is cyclone in simple words?
What is cyclone in simple words? In meteorology, a cyclone refers to any low pressure area with winds spiralling inwards. Cyclones rotate clockwise in the Southern Hemisphere and anti-clockwise in the Northern Hemisphere. Cyclones are also referred to as hurricanes and typhoons. What are the types of cyclones? There are two types of cyclones: Tropical […]
What are the main parts of nuclear power station?
What are the main parts of nuclear power station? 2.2 Components of a nuclear power station The fuel. The elements that undergo the fission are generally uranium (U) or plutonium (Pu). The control rods. A nuclear fission reaction at criticality can be maintained by controlling the critical mass (as you heard about in Week 1). […]
How does tectonic uplift occur?
How does tectonic uplift occur? Uplift, in geology, vertical elevation of the Earth’s surface in response to natural causes. Uplift of the Earth’s surface also has occurred in response to the removal of Pleistocene ice sheets through melting and wastage. What is the difference between uplift and subsidence? Terms in this set (2) What is […]
What determines if a bond is covalent or ionic?
What determines if a bond is covalent or ionic? Compounds containing two elements (so called binary compounds) can either have ionic or covalent bonding. If a compound is made from a metal and a non-metal, its bonding will be ionic. If a compound is made from two non-metals, its bonding will be covalent. Why KCl […]
Why are there only odd harmonics?
Why are there only odd harmonics? When are they a problem Most electrical loads (except half-wave rectifiers) produce symmetrical current waveforms, which means that the positive half of the waveform looks like a mirror image of the negative half. This results in only odd harmonic values being present. Why 3rd harmonics is dangerous? The third […]
