How far can electricity be transmitted efficiently? As of 1980, the longest cost-effective distance for direct-current transmission was determined to be 7,000 kilometres (4,300 miles). For alternating current it was 4,000 kilometres (2,500 miles), though all transmission lines in use today are substantially shorter than this. What are the three parts of the electrical system? […]

Which is not characteristics of minerals? Question 1: Which one of the following is NOT a characteristic of minerals? They are created by natural processes. They have a definite chemical composition. They are inexhaustible. Which of the characteristics of minerals is not a concern of geographers? Answer. It is much hardness of the mineral which […]
How can you increase the efficiency of a solar collector?
How can you increase the efficiency of a solar collector? The radiations coming from the sun’s energy were converted into heat, and then this heat was transferred to the collector fluid, water. A prototype of a solar water heating system was constructed and obtained the improvement of the collector efficiency around 10% by using the […]
What factors contribute to a decrease in population once carrying capacity is reached?
What factors contribute to a decrease in population once carrying capacity is reached? While food and water supply, habitat space, and competition with other species are some of the limiting factors affecting the carrying capacity of a given environment, in human populations, other variables such as sanitation, diseases, and medical care are also at play. […]
When did you find the highest difference in the recorded temperature?
When did you find the highest difference in the recorded temperature? The official highest recorded temperature is now 56.7°C (134°F), which was measured on 10 July 1913 at Greenland Ranch, Death Valley, California, USA. Can the difference between two temperatures be negative? If you were asked “How much higher is the boiling point of X […]
What are two things through which water moves?
What are two things through which water moves? Water in different phases moves through the atmosphere (transportation). Liquid water flows across land (runoff), into the ground (infiltration and percolation), and through the ground (groundwater). Does the phloem transport water? Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from […]
Is it possible for an object to be in motion if no net force is acting on it explain?
Which condition is necessary for enzymes and hormones to function properly in the human body?
Which condition is necessary for enzymes and hormones to function properly in the human body? Enzymes can only work in certain conditions. Most enzymes in the human body work best at around 37°C – body temperature. At lower temperatures, they will still work but much more slowly. Similarly, enzymes can only function in a certain […]
Why are warm windy days the best days to hang out your washing?
