How is air pressure usually measured? A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure. What time […]

What is the primary role of frontal lobe?
What is the primary role of frontal lobe? As a whole, the frontal lobe is responsible for higher cognitive functions such as memory, emotions, impulse control, problem solving, social interaction, and motor function. Damage to the neurons or tissue of the frontal lobe can lead to personality changes, difficulty concentrating or planning, and impulsivity. Which […]
What is electronegativity How does it vary in group and period?
What is electronegativity How does it vary in group and period? The tendency of an atom to attract the shared pair of electrons towards itself is known as electronegativity. Electronegativity increases across a period while it decreases down a group. Atomic radius increases down the group due to addition of new shell. How does electronegativity […]

What forms of energy changes take place when a gun is fired?
What forms of energy changes take place when a gun is fired? A bullet stores chemical potential energy in its gunpowder. When the bullet is fired, this chemical energy is converted into kinetic energy and heat. Why does the Dart have a little bit of gravitational potential energy before it is fired? However, the dart […]
What are 4 energy concerns?
What are 4 energy concerns? In this section we examine some problems associated with the use of fossil fuels, fuel wood, uranium, hydro power plants and wind energy….Global warming Rise in mean (average) global temperature. Rising sea levels. Occurrence of weather extremes. Shifting of vegetative zones. What is the world’s energy problem? The energy problem […]
Is gravity created by mass?
Is gravity created by mass? So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight. Does rotation affect gravity? While the spinning of the […]
What is the coldest dwarf planet?
What is the coldest dwarf planet? However, since 2006, Pluto is no longer considered to be a planet because specialists have realized that it is much smaller than we imagined, giving it the status of a dwarf planet. Today, two planets can claim the title of “coldest planet in the solar system”: Neptune and Uranus. […]
