Is Earth 666 destroyed? Earth-666 was destroyed by antimatter during the Anti-Monitor Crisis. Why is it called Earth 616? The main Marvel universe was labeled as 616. Alan Moore chose this designation as a counter to the single-digit numbers for earths in DC. He wanted to emphasize that the main earth was not special. 616 […]
Where do we find the fastest moving galaxies?
Where do we find the fastest moving galaxies? In the center of our Milky Way galaxy, scientists have spotted the fastest star ever detected, moving at more than 8% of the speed of light. Our galaxy’s center features the supermassive black hole Sagittarius A* (Sgr A*), which is as massive as about 4 million suns. […]
Can something have more than one type of energy?
Can something have more than one type of energy? Energy comes in many different types, which can be categorised into two basic forms – kinetic and potential. Energy can never be created or destroyed, but it can be transformed from one type of energy to another. What happens if you drop the skater onto the […]
Do windmills kill bats?
Do windmills kill bats? Dead bats are found beneath wind turbines all over the world. It’s estimated that tens to hundreds of thousands die at wind turbines each year in North America alone. These bats migrate and mate primarily during late summer and early autumn, which is also when the vast majority of bat fatalities […]
Do heavier objects fall faster?
Do heavier objects fall faster? Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. How do you find velocity with time and height? An object is thrown straight up from the top of a building h feet tall […]
What does static pressure mean?
Can you open a digital gun safe with a magnet?
Can you open a digital gun safe with a magnet? Locksmith demonstrated recently at a business meeting in Vancouver, Canada. He showed that, using a rare earth magnet, one can exploit the nickel piece in this Sentry Electronic Safe to get it open without any damage. Are Cannon safes easy to break into? Whether you […]
How do you find the refractive index of water?
How do you find the refractive index of water? The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in […]
What are two types of scientific explanation?
What are two types of scientific explanation? Among the most common forms of explanation are causal explanation; deductive-nomological explanation, which involves subsuming the explanandum under a generalization from which it may be derived in a deductive argument (e.g., “All gases expand when heated; this gas was heated; therefore, this gas expanded”); and … Is Hempel […]
Does speed of sound depend on humidity?
Does speed of sound depend on humidity? The speed of sound is affected by temperature and humidity. Because it is less dense, sound passes through hot air faster than it passes through cold air. Dry air absorbs far more acoustical energy than does moist air. This is because moist air is less dense than dry […]
