What is the direction of magnetic field in a bar magnet? Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the […]

Is hydrogen peroxide supposed to foam?
Is hydrogen peroxide supposed to foam? Hydrogen peroxide does not foam in the bottle or on your skin because there is no catalase to help the reaction to occur. Hydrogen peroxide is stable at room temperature. What is the changing of liquid to a gas called? At a certain temperature, the particles in a liquid […]
Which type of orbital is not allowed?
Which type of orbital is not allowed? The answer is d) 2d. Without going into too much detail, the 2d orbitals cannot exist because they are not allowed solutions to the Schrodinger equation. Simply put, the second energy shell, designated by a principal quantum number equal to 2, or n=2 , can only hold s […]

How many independent variables should an investigation have? one independent variable What’s the dependent variable in science? The dependent variable is the variable that is being measured or tested in an experiment. […]
What happens when satellites crash?
What happens when satellites crash? The Short Answer: Two things can happen to old satellites: For the closer satellites, engineers will use its last bit of fuel to slow it down so it will fall out of orbit and burn up in the atmosphere. Further satellites are instead sent even farther away from Earth. How […]
What is the function of sodium ion in human body?
What is the function of sodium ion in human body? Sodium is both an electrolyte and mineral. It helps keep the water (the amount of fluid inside and outside the body’s cells) and electrolyte balance of the body. Sodium is also important in how nerves and muscles work. Most of the sodium in the body […]
What is a high resistance wire?
What is a high resistance wire? Resistance wire is used to control the amount of current in a circuit. High resistivity is better since a shorter wire can then be used. When it is used for heating elements for applications such as electric heaters and toasters, high resistivity and oxidation resistance is important. What’s the […]
Which is better if the discharge time of the capacitor is small or large?
Which is better if the discharge time of the capacitor is small or large? At first the current is large because the voltage is large, so charge is lost quickly and the voltage decreases rapidly. As charge is lost the voltage is reduced making the current smaller so the rate of discharging becomes progressively slower….Discharging […]
