Can a plane fly through a storm? All planes are designed to fly through storms and have to comply with safety regulations. A rainstorm is unlikely to cause damage to the aircraft. The only danger of flying through a rainstorm is the risk of freezing rain, but in this case, your plane will most likely […]

Are located in the center of the periodic table? The transition metals make up the middle block of the periodic table. Like the other elements that are grouped together (alkali metals, noble gases), these metals have very similar properties. Professor Stahl and his research group work with many of the transition metals. Below is a […]

Why do long jumpers land sand? Athlete is made to land on the sand after long jump so as to increase the time of impact. This reduces the momentum and force by which he is landing on the ground. Thus, athlete is saved from getting injured. Why does an athlete put some sand? Why does […]

What does 1 Coulomb look like? One coulomb is equal to the amount of charge from a current of one ampere flowing for one second. One coulomb is equal to the charge on 6.241 x 1018 protons. The charge on 1 proton is 1.6 x 10-19 C. Conversely, the charge of an electron is -1.6 […]

Do termites eat Hardie board? As we’ve mentioned, Hardie Board, vinyl, and metal siding are impervious to pests. Termites and carpenter ants eat wood, but the wood pulp used in Hardie board is infused with cement, so the pests have no interest or access to it. Does Hardie board increase value of home? James Hardie […]

How does double rainbow occur? Double rainbows are formed when sunlight is reflected twice within a raindrop with the violet light that reaches the observers eye coming from the higher raindrops and the red light from lower raindrops. What does it mean to see a double rainbow? A double rainbow is considered a symbol of […]

What is the object distance when a virtual image is formed at a distance of 30 cm? If the object distance (u) is 30 cm and image distance (v) is also 30cm. Then, f=15cm. What is the position of the image when an object is placed at a distance of 30 cm from a concave […]

What enzyme converts glucose into ethanol? Zymase What are the two methods of producing ethanol? It can be produced from petroleum via chemical transformation of ethylene, but it can also be produced by fermentation of glucose, using yeast or other microorganisms; current fuel ethanol plants make ethanol via fermentation. What is the enzyme in yeast […]
