Does a fridge use AC or DC? Unfortunately, you can’t plug an AC refrigerator straight into a DC power source. You need a power inverter between the source and the refrigerator. So the power converts from DC to AC through the inverter, goes into the refrigerator and converts to DC again. During each stage of […]
How do you study chemical equilibrium?
How do you study chemical equilibrium? Chemical equilibrium is attained when the concentration of reactants and products stops changing. Since reactants and products eventually reach a constant value (given constant temperature and pressure) a ratio called the rate constant can be used to describe the equilibrium. What is the first step in order to calculate […]
What happens to the current in a coil while accelerating a magnet inside it?
What happens to the current in a coil while accelerating a magnet inside it? 2. What happens to the current in a coil while accelerating a magnet inside it? Explanation: A change in the magnetic field induces an emf. Hence, when the magnet is moved inside a coil, the current in it increases. What is […]
What causes temperature differences in the atmosphere?
What causes temperature differences in the atmosphere? Rock, soil, and water on Earth absorb the Sun’s light and radiate it back into the atmosphere as heat. The temperature is also higher near the surface because of the greater density of gases. The higher gravity causes the temperature to rise. Notice that in the troposphere warmer […]
Why is taurine banned?
Why is taurine banned? The drink had been banned in France for twelve years due to health authorities’ concerns about unknown consequences of the ingredient taurine, a chemical forbidden in several countries. It added that it suspected the drink lessens the impression but not the effects of drunkenness when consumed with alcohol. Why is taurine […]
How do you find specific volume?
Which of the following answer choices correctly sequences the path of urination in the body?
Which of the following answer choices correctly sequences the path of urination in the body? So, the correct answer is ‘Kidney ureters bladder urethra’. Which structure is the first to collect urine? Answer and Explanation: Metabolic waste is considered urine first in the collecting duct of the nephron. From the collecting duct, the urine will […]
What is the rule of atmosphere?
What is the rule of atmosphere? The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun’s dangerous rays from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life. What are the benefits of having an atmosphere? What […]
What is power in sample size calculation?
What is power in sample size calculation? Power calculations tell us how many patients are required in order to avoid a type I or a type II error. The term power is commonly used with reference to all sample size estimations in research. Strictly speaking “power” refers to the number of patients required to avoid […]
Is the reactant which has the lowest coefficient in a balanced equation?
Is the reactant which has the lowest coefficient in a balanced equation? limiting reactant Do you use limiting reagent to calculate theoretical yield? A limiting reagent is a chemical reactant that limits the amount of product that is formed. The limiting reagent gives the smallest yield of product calculated from the reagents (reactants) available. This […]
