Which is kept in kerosene? Sodium Can sodium and potassium be stored in water? Explanation: Sodium and potassium metals reacts very vigorously with water; this reaction gives out so much heat that the hydrogen evolved catches fire. Therefore, these metals are stored under kerosene. What happens when you mix potassium and sodium? Sodium reacts more […]
What is the change in internal energy for a system that does 70j?
What is the change in internal energy for a system that does 70j? Answer. According to First Law of Thermodynamics, ⇒ Internal energy (ΔU)= q+W = (-45)+70 = -25 J. What is the change in internal energy U for a system? One way we can increase the internal energy U (and therefore the temperature) of […]
How can we identify a particular element?
How can we identify a particular element? Explanation: There are two properties that can be used to identify an element: the atomic number or the number of protons in an atom. The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in […]

What are the 3 principles of training?
What are the 3 principles of training? In summary, the three principles of training that should be followed in developing your fitness program are overload, progression, and specificity. When you increase the repetitions, amount of weight, or length of time in an exercise you’re accustomed to, you’re applying overload. Which principle do you feel is […]
Can I reverse a transformer?
Can I reverse a transformer? When a transformer is reverse fed, the taps move to the output side and so their operation is reversed. For reverse fed applications, raising the taps will increase output voltage and lowering the taps will lower output voltage. What is the difference between step up transformer and step down transformer? […]
How do you make an RCC building earthquake resistant?
How do you make an RCC building earthquake resistant? Another method to reduce failure during earthquakes is to design a strong core shear wall in seven to 20 storey RCC structures. Typically, this is designed in the elevator area. If the shear wall is designed as per relevant code, it can provide necessary stiffness to […]
Can I take a picture of something and Google it?
Can I take a picture of something and Google it? The Google Goggles app is an image-recognition mobile app that uses visual search technology to identify objects through a mobile device’s camera. Users can take a photo of a physical object, and Google searches and retrieves information about the image. How do I reverse search […]
