What is the difference between clay and sand? The largest, coarsest mineral particles are sand. These particles are 2.00 to 0.05 mm in diameter and feel gritty when rubbed between your fingers. Silt particles are 0.05 to 0.002 mm and feel similar to flour when dry. Clay particles are extremely fine — smaller than 0.002 […]
Which two player positions are the only ones that can shoot?
Which two player positions are the only ones that can shoot? Goal Attack (GA) and Goal Shooter (GS) are the only players allowed to shoot and score goals. Shots must be taken within the shooting circle, sometimes referred to as the D or semi-circle. Can you bounce the ball off the post in netball? A […]
How is work related to internal energy?
How is work related to internal energy? The relationship between the internal energy of a system and its heat and work exchange with the surroundings is: E = q + w (The form of work will be restricted to gaseous, PV-type for this discussion.) Interestingly, both q and w are not state functions. What is […]
Do metals have low resistivity?
Do metals have low resistivity? Any impurity whether metallic or non metallic increase the resistivity of metals. Even an impurity of low resistivity will increase the resistivity of metal….Required Properties in high Low Resistivity or High Conductivity Conducting Material. Sl No. 4 Metals Aluminum Chemical Symbol Al Resistivity (µΩ -cm) 2.65 Which of the following […]
What are the three ways heat can be transferred?
What are the three ways heat can be transferred? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer […]
What is an example of prime meridian?
What is an example of prime meridian? The prime meridian is a reference line through Greenwich, England that measures longitude east and west. An example of prime meridian is zero degrees longitude. The meridian from which longitude is measured both east and west; 0° longitude: it passes through Greenwich, England. Why was Greenwich chosen as […]
How do you find the internal energy of an ideal gas?
Does volcanic ash poison water?
Does volcanic ash poison water? The USGS adds, “closer to the volcano, water-soluble components that cling to particles of glass and crystals in the ash may lead to chemical changes,” which can temporarily make the water too toxic to drink. Smaller pieces of ash in particular pose significant problems for fresh water supplies. Does volcanic […]
Which of these is an example of freshwater wetlands?
Which of these is an example of freshwater wetlands? Marshes, bogs, and lakes are examples of freshwater wetlands. Are all wetlands freshwater? Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish, or saltwater. The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, […]
Why did AM radio die out?
Why did AM radio die out? The decline in AM audio was due more to regulation than to method of modulation. One aspect of radio not understood by most listeners is the concept of occupied bandwidth, or the amount of spectrum that a station uses to transmit its signal. Are old radios dangerous? Vintage radio […]
