Which of the following relations is correct for permeability? The correct relation between magnetic susceptibility and relative permeability is- 1 x = Ur-1 2 x = 4r + 1 3 x = u + 1 4 x = u – 1. What is relationship between μ and ɸ *? There is an inverse relationship between […]

Does touch up paint last? Touch Up Paint Should Last At Least 4-5 Years The smaller the damage, the better the application, the more likely the touch-up paint will last until you’re ready to move on to another car. You still need to wash and wax the car. And if other scratches or damage occur, […]

How do you find the buoyant force of a balloon? Buoyant Force of Balloons The formula for buoyant force is: (B) = ρ V g. ρ = Density of Fluid (We used density of the air because the balloons were afloat, not submerged) V = Displaced Volume. g = 9.8 (gravity) Density of air(ρ)= 1.225 […]

Is the Chernobyl reactor still burning? So Is Chernobyl Still Burning? Yes, but it is not what you think. Chernobyl still burns due to wildfires, According to Greenpeace organization wildfire started on April 3rd, due to abnormally hot, dry and windy weather.

What is the difference between structural and ball and stick model? A molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. A structural formula indicates the bonding arrangement of the atoms in the molecule. Ball-and-stick and space-filling models show the geometric arrangement of atoms […]

What do numbers symbolize on the speedometer? it shows is the distance your bike has covered. If the right number is in a white dial, it means that it shows the meters in 100s covered. So, if it shows 22595 with 5 being in the white dial, that means the distance covered is 2259 km […]

What is produced when aluminum reacts with hydrochloric acid? Aluminum metal reacts with hydrochloric acid to form hydrogen gas and an aluminum chloride solution. In this investigation, you will predict the mass of hydrogen gas produced by a given amount of reactants, then measure the amount, and compare them. Hydrochloric acid is an aqueous solution […]

Is it safe to run a dehumidifier constantly all the time? No, it is not necessary to run your dehumidifier all the time. You should only run your unit when the humidity level is above 50 percent. Collecting water constantly with a dehumidifier does really help you maintain the temperature and relative humidity at an […]

Why hydrogen ion does not exist? Because the bare nucleus can readily combine with other particles (electrons, atoms, and molecules), the isolated hydrogen ion can exist only in a nearly particle-free space (high vacuum) and in the gaseous state. Why are H+ ions? Loss of an electron from H atom results in H+ . ion […]
