What should a good hypothesis have? A good hypothesis is stated in declarative form and not as a question. “Are swimmers stronger than runners?” is not declarative, but “Swimmers are stronger than runners” is. 2. A good hypothesis posits an expected relationship between variables and clearly states a relationship between variables. What is a systematic […]
Do insurance companies check points?
Do insurance companies check points? No. Although insurers are allowed to ask about spent points, it is illegal for these to influence how a company prices your cover. How much does insurance go up per point? Getting points on your license — which is the result of a traffic violation — will typically lead to […]
How many kVA is 5kw?
What is the oxidation number of oxygen in peroxide?
What is the oxidation number of oxygen in peroxide? -1 Which groups have both positive and negative oxidation states? Well the most relevant answer is iodine… iodine electronegativity and polarizability is responsible for both positive and negative oxidation state.. What is the oxidation state of S in Caro’s acid? – Therefore the oxidation state of […]

Why do ducks easily swim in freshwater?
Why do ducks easily swim in freshwater? All ducks have what’s called a uropygial gland, or an oil gland, near the base of the tail. This gland secretes a special oily substance that the duck spreads over his entire body using his beak. The oil coats his feathers, making them water-resistant. Can a one legged […]
What is 180 degrees out of phase?
What is 180 degrees out of phase? 180 degrees out of phase is completely backwards, which is characterized by one signal’s highest peak correlating with another’s most negative peak. Most signals are not entirely in phase with each other, and it’s just as rare for them to be perfectly (180 degrees) out of phase. Why […]
What happens if you remove electrons from an atom?
What happens if you remove electrons from an atom? If we remove an electron from a stable atom, the atom becomes electrically incomplete/unbalanced. That is, there are more protons in the nucleus (positive charges) than there are electrons (negative charges). With an electron removed, the atom possesses a plus one charge, therefore it is a […]
Which best describes an electric current?
Which best describes an electric current? An electric current is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes. Which […]
Why is electromagnet preferred over permanent magnet?
Why is electromagnet preferred over permanent magnet? The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain […]
