What is the first step of solar system formation? Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the […]

Why did Mendel use pea plants?
Why did Mendel use pea plants? To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits (Figure below). For example, pea plants are either tall or short, which is an easy trait to observe. Mendel also used pea plants because they can either self-pollinate or be cross-pollinated. What are […]
What are the 4 stages of a fire?
What are the 4 stages of a fire? Compartment fire development can be described as being comprised of four stages: incipient, growth, fully developed and decay (see Figure 1). What are the signs of poor housekeeping? Signs of poor housekeeping Cluttered or poorly organized work spaces. Untidy or dangerous storage of materials (e.g. dangerous stacking […]
What is the condition for second order of Spectra?
What is the condition for second order of Spectra? When the pathlength difference is two wavelengths, another bright image occurs (the second order diffraction maximum). If light of a longer wavelength is used, the maxima are at larger angles. When light of multiple wavelengths is used, the different wavelengths(different colors) are separated. How many orders […]
What has the most gravitational potential energy?
What has the most gravitational potential energy? Higher objects (with further to fall) have greater potential energy. The heaviest of 2 objects at the same height has the greatest gravitational potential energy. Is it possible for a system to have negative gravitational potential energy? The gravitational potential energy could even be negative if the object […]
Why position Absolute is bad?
Why position Absolute is bad? Using absolute positioning is far more rigid and makes it difficult to write layouts that respond well to changing content. They’re simply too explicit. Should I use position absolute? In some cases, absolute positioning breaks faster and it’s better to use floats, while in other situations it’s better to use […]
Which one of these four atoms has the most neutrons ABCD?
Which one of these four atoms has the most neutrons ABCD? From the above information, it is visible that Krypton has most neutrons. Hence, the correct answer is Option D. What is the mass defect of oxygen 16 Assume the following? Answer Expert Verified In this case, the total mass of the nucleons is solved […]
What is the importance of lithium fluoride?
What is the importance of lithium fluoride? Lithium fluoride is most widely used as a flux in the production of ceramics, such as enamels, glasses and glazes. Similarly it is also used in brazing and welding fluxes and molten salt chemistry in metallurgy. Does lithium fluoride react with water? Elementary lithium is not very water […]
What parts of Canada are missing gravity?
What parts of Canada are missing gravity? Gravity in the Hudson Bay area and surrounding regions, including Quebec, is lower than it is in other parts of the world. For more than 40 years, scientists have tried to figure out what’s causing large parts of Canada, particularly the Hudson Bay region, to be “missing” gravity. […]
