Why do pencils look bent in water? A:It all has to do with the fact that light travels more slowly in water than it does in air, and that causes the light to bend when it goes from water to air, or vice versa. And that makes the pencil look like it bends slightly where […]
What is the IQ of a koala?

Despite looking very cute and cuddly, koalas are considered neither smart nor intelligent and even considered as dumb. Are koalas the dumbest animal? #8 Dumbest Animals in the World: Koala But most of that is because their brain levels […]
Which of the following is the example of d6 low spin complex?
Which of the following is the example of d6 low spin complex? Examples of low-spin d6 complexes are [Cr(CN)6]3− and Cr(CO)6, and examples of high-spin d6 complexes are [CrCl6]3− and Cr(H2O)6. How do you know if a ligand is a strong or weak field? Ligands that bind through very electronegative atoms such as O and […]
What did vision scientist James Foster find when he tested dung beetles ability to navigate over a lunar month?
What did vision scientist James Foster find when he tested dung beetles ability to navigate over a lunar month? It turns out that dung beetles rely specifically on the polarization of light – the orientation of the light waves – to orient themselves. Researchers led by James Foster from Lund University in Sweden set out […]
What will happen when two bodies of different temperature are placed in thermal contact?
What will happen when two bodies of different temperature are placed in thermal contact? If two objects at different temperatures are brought in contact with each other, energy is transferred from the hotter object (that is, the object with the greater temperature) to the colder (lower temperature) object, until both objects are at the same […]
What are the negative effects of renewable energy?
What are the negative effects of renewable energy? All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions. What […]
Is concrete a viscoelastic material?
Is concrete a viscoelastic material? The mechanical behavior of concrete under dynamic loading is viscoelastic, while it is nonlinear elastic under quasi-static conditions. What is viscoelastic material used for? Viscoelastic materials are used in automobile bumpers, on computer drives to protect from mechanical shock, in helmets (the foam padding inside), in wrestling mats, etc. Viscoelastic […]
Can someone look better in person than photos?
Can someone look better in person than photos? No, some people really do look better in person. The thing about pictures is that they’re static, which is a little bit of a mindbend when you think of how much motion the average human face articulates on a daily basis. There’s also the interplay of lighting, […]
How does energy flow in a food chain?
How does energy flow in a food chain? Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers. They are then eaten by tertiary consumers and in a long food day these can be eaten by quaternary […]
