Why do ionic compounds have high melting and boiling points? It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. The greater the charge on the ions, the stronger the forces holding them together. Is K2O covalent or […]
What is the approximate air temperature at the top of Mount Everest?
What is the approximate air temperature at the top of Mount Everest? If we speak mathematically how the temperature decreases with the altitude than the temperature at Mount Everest should be -86.73 C degrees given that the temperature at zero altitude is 0 C degrees. How much colder is it in the mountains? If there’s […]
What is the relationship between a particular latitude and the angle of Polaris?
What is the relationship between a particular latitude and the angle of Polaris? Because the earth is spherical, the position of Polaris relative to the horizon depends on the location of the observer. Consequently, the angle between the northern horizon and Polaris is equal to the observer’s latitude. Will Polaris always be the pole star? […]
What are vital signs for animals?
What are vital signs for animals? Vital signs are measurements of the body’s most basic functions. The main vital signs routinely monitored by veterinarians are body temperature, pulse rate and respiratory rate. Vital signs are useful in detecting or monitoring medical problems. What is the importance of determining the vital signs of an animal? Vital […]
How do we know the shape of Milky Way?
What are the 7 parts of the ocean floor?
What are the 7 parts of the ocean floor? Vocabulary abyssal plain. continental shelf. continental slope. mid-ocean ridge. oceanic trench. seamount. sonar. What does the center slit of your model represent? The center slit represents a Mid-Ocean Ridge 2. The strips of paper represent oceanic crust or seafloor. Seafloor spreading is the creation of new […]
What is the nature of the force between two parallel current carrying wires in same direction?
What is the nature of the force between two parallel current carrying wires in same direction? The force between the two parallel conductors is attractive in nature if the current is flowing in same direction in both the conductors whereas the force is repulsive if the current is flowing in opposite direction in the conductors. […]
What is a medium in terms of writing?
What does Y represent in an equation?
What are 2 types of competition?
What are 2 types of competition? By mechanism. Competition occurs by various mechanisms, which can generally be divided into direct and indirect. These apply equally to intraspecific and interspecific competition. Biologists typically recognize two types of competition: interference and exploitative competition. What is an example of competitive exclusion? The principle of competitive exclusion was proposed […]
