What are 2 similarities and 2 differences between ionic and covalent bonds? The molecules that are formed from the ionic and covalent bonds are neutral. This is because, in an ionic bond, two opposite charges cancel each other while in a covalent bond, neutral components shared the pair of electrons. Ionic and covalent, both are […]

How do you treat multidrug resistant bacteria? Current Treatment Options for MDR-GNB in Critically-ill Patients Polymyxins. Polymyxins acts as detergents of the outer membrane of GNB, exerting bactericidal activity. Aminoglycosides. Tigecycline. Carbapenems. Fosfomycin. Ceftazidime/Avibactam. Meropenem/Vaborbactam. Ceftolozane/Tazobactam. How serious is Mdro? Infection. When a person gets sick because of the bacteria, they are infected with the […]

What is Pascal law and its derivation? In the 1600’s, French scientist (Methematcian) Blaise Pascal (1623-1662) discovered one fact which is termed as Pascal’s Law. Pascal’s Law. According to Pascal’s Law, “Pressure or intensity of pressure at a point in a static. fluid will be equal in all directions”. What is Pascal’s law state its […]

Does oxygen form a positive or negative ion? Negative ions are called anions . Oxygen is in group 6. An oxygen atom has six electrons in its outer shell. The atom is more stable if it has a full outer shell….Forming negative ions. Atom name Ion name Sulfur Sulfide Which form of oxygen is the […]

Who is the father of cosmology? ACHARYA KAPIL How do Cosmologists study the universe? There are two main ways in which cosmological observations support perturbed FLRW models. First, cosmologists use matter and radiation in the universe to probe the background spacetime geometry and its evolution. What is Africa cosmology? In the framework of African cosmology, […]

How do you use a pulley to multiply forces? To lift something four times heavier, you can use exactly the same force but only if you pull the rope four times further. If you look at what’s happening on both sides of a pulley, and multiply the force by the distance moved, you’ll find it’s […]

Do projectiles have a predictable path? Projectiles do not follow a predictable path. Where will the ball have the smallest speed? The speed is smallest at the highest point of its flight path because the y- component of the velocity is zero. At what point of the projectile path the speed is i minimum and […]

Is negative free cash flow a bad sign? Although companies and investors usually want to see positive cash flow from all of a company’s operations, having negative cash flow from investing activities is not always bad. Can you have negative cash flow and positive profit? Cash flow is the net amount of cash and cash-equivalents […]

Can you wire a 3 pin plug with 2 wires? No, it’ll be fine. You need an earth wire when you’ve got metal casings on appliances; the earth wire provides a preferred path to ground for a fault which results in the casing becoming live (ie, a preferred path to that path being ‘you’). Can […]

What are the similarities and differences between kinetic and potential energy? KE is the energy possessed by an object by virtue of it being in motion. PE is the energy possessed by an object by virtue of its position. It can be transferred from one object to another and this happens during collisions. Potential Energy, […]
