What is the height of the ocean? Its elevation is 400 meters (1,312 feet) below sea level. However, if depth were measured from the ocean floor, the Challenger Deep in the Pacific Ocean would be the lowest place on Earth. It measures 11,034 meters (36,200 feet) below sea level. Why is the sea not flat? […]
How dangerous is ground-level ozone?
How dangerous is ground-level ozone? Breathing elevated concentrations of ozone can trigger a variety of responses, such as chest pain, coughing, throat irritation, and airway inflammation. It also can reduce lung function and harm lung tissue. Ozone can worsen bronchitis, emphysema, and asthma , leading to increased medical care . How can ground-level ozone be […]
Does heat affect light?
Does heat affect light? Heat does not directly affect the light, but it does indirectly interact with light in two ways. Heat causes a slight change in the refractive index of the medium. Why does heat make things blurry? As the hot and cool air mix, light that’s traveling through the air goes in and […]
What is the most active element in Group 17?
What is the most active element in Group 17? FLUORINE What are the horizontal rows called? Each box represents an element and contains its atomic number, symbol, average atomic mass, and (sometimes) name. The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups. Groups are labeled at […]

Are factors that the experiment is changing?
Are factors that the experiment is changing? The things that are changing in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. What part of an experiment does not change? Control […]
What is the unit of Hall coefficient?
What is the unit of Hall coefficient? The two most widely used units for the Hall coefficients are SI units, m3/A-sec = m3/C, and the hybrid unit Ohm-cm/G (which combines the practical quantities volt and amp with the cgs quantities centimeter and Gauss). How do you calculate Hall effect? Hall Voltage for Positive Charge Carriers […]
What is an example of an inexhaustible resource?
What is an example of an inexhaustible resource? Inexhaustible Natural resources – Inexhaustible resources of energy are those sources, which will not exhaust in future. These are unlimited. Bio-mass is one of the inexhaustible sources of energy. Examples – Air, water and sunlight. Is water an inexhaustible? Ex-as in summer season the river gets dried […]
How does heat move away from the earth?
How does heat move away from the earth? Energy is transferred between the Earth’s surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection. […]
