Is absolute dating better than relative? In relative dating, fossils are dated according to the depth at which they were buried. While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils. What is the […]

What is the velocity of star?
What is the velocity of star? In the Milky Way, stars usually have velocities on the order of 100 km/s, whereas hypervelocity stars typically have velocities on the order of 1000 km/s. Most of these fast-moving stars are thought to be produced near the center of the Milky Way, where there is a larger population […]
What are the similarities and differences between the somatic nervous system and the autonomic nervous system?
What are the similarities and differences between the somatic nervous system and the autonomic nervous system? The somatic nervous system has sensory and motor pathways, whereas the autonomic nervous system only has motor pathways. The autonomic nervous system controls internal organs and glands, while the somatic nervous system controls muscles and movement. What is the […]
What are the equations of motion in circular path?
Why is there a difference between Celsius and Fahrenheit?
Why is there a difference between Celsius and Fahrenheit? Celsius scale, or centigrade scale, is a temperature scale that is based on the freezing point of water at 0°C and the boiling point of water at 100°C. Fahrenheit scale is a temperature scale that is based on the freezing point of water at 32°F and […]
Does Vantablack absorb heat?
Does Vantablack absorb heat? Vantablack converts light energy over a wide spectral range into heat energy, making it the blackest substance known (99.965% absorption of incident radiation). How much does Vantablack heat up? Vantablack absorbs up to 99.965% of visible light and can be created at 400 °C (752 °F). Can Vantablack boil water? Fun […]
What is the relationship between metallic and ionization energy?
What is the relationship between metallic and ionization energy? Metallic character refers to the level of reactivity of a metal. The metallic character increases as you go down a group. Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to […]
What gases are released when wood burns?
What gases are released when wood burns? When wood is burned, the combustion reaction produces heat and emissions in the form of water, organic vapors, gases, and particulates. The emissions of most concern are carbon monoxide (CO), carbon dioxide (CO2), sulfur oxides (SOx), and nitrogen oxides (NOx). Does burning wood cause global warming? Scientists estimate […]
What is the most dangerous penguin?
What is the most dangerous penguin? Adélie Do penguins think humans are penguins? Penguins have no special fear of humans and will often approach groups of people. This is probably because penguins have no land predators in Antarctica or the nearby offshore islands. Instead, adult penguins are at risk at sea from predators such as […]
