Are noble gases each a different color? Each of the noble gasses glows in its own colour when exposed to high voltage; for example helium becomes pink, krypton glows yellow/green, xenon shines in lavender blue and argon in light blue. What does argon smell like? Argon has no smell. It is a colorless gas. It […]
Is angular momentum conserved rolling without slipping?
Is angular momentum conserved rolling without slipping? In rolling motion without slipping, a static friction force is present between the rolling object and the surface. A rigid rotating body has angular momentum directed along the axis of rotation. 11.4: Conservation of Angular Momentum. In the absence of external torques, a system’s total angular momentum is […]
How does a dimming mirror work?
How does a dimming mirror work? Technology. In auto dimming mirror technology, a forward-looking sensor detects low ambient light from headlights behind the car and directs the rear-view sensor to look for glare. The mirrors darken automatically in proportion to how bright the glare is, then clear once the glare is no longer detected. Why […]
Which compound becomes less soluble in water as the temperature of the solution is increased a HCl B KCl C NaCl D nh4cl?
Which compound becomes less soluble in water as the temperature of the solution is increased a HCl B KCl C NaCl D nh4cl? Thus, out of the given options HCl is a covalent compound, therefore, HCl is the compound that becomes less soluble in water as the temperature of the solution is increased. Why does […]
Why onion has no chloroplast?
Why onion has no chloroplast? The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onion fruiting body (bulb) is used for storing energy, not photosynthesis. The vacuole is prominent and present at the center of the cell, surrounded by cytoplasm. Do plant cells have chloroplasts and mitochondria? Plant […]
What are examples of lava plateau?
What are examples of lava plateau? The magma that comes out through narrow cracks or fissures in the crust spread over large area and solidifies. These layers of lava sheets form lava or volcanic plateaus. The Antrim plateau in Northern Ireland, The Deccan Plateau in India and the Columbia Plateau in the United States are […]
Which of the following is a white crystalline solid?
Which of the following is a white crystalline solid? Magnesium Oxide is an ionic compound, formed by the transfer of electrons from one element to the other. Since it is an ionic compound, MgO is solid. It is also white and crystalline in nature. What is meant by a crystalline solid? Crystalline solids consist of […]
What is ionized helium?
What is ionized helium? Singly ionized helium is an atom that has lost one of its electrons. We must expect its remaining electron to act like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom; number of protons in the nucleus, so the nuclear charge. What […]
Why is area and perimeter important?
Why is area and perimeter important? Perimeter and Area. Perimeter and area are two important and fundamental mathematical topics. They help you to quantify physical space and also provide a foundation for more advanced mathematics found in algebra, trigonometry, and calculus. What is the importance of perimeter in real life? In everyday life area and […]
Can a person live without bone marrow?
Can a person live without bone marrow? It is the blood cell ‘factory’. Healthy bone marrow releases blood cells into the bloodstream when they are mature and when required. Without bone marrow, our bodies could not produce the white cells we need to fight infection, the red blood cells we need to carry oxygen, and […]
