How do I make my house safe from radon? An active radon sump, fitted with a fan, is the most effective way to reduce indoor radon levels. Sumps work best under solid floors and under suspended floors if the ground is covered with concrete or a membrane. Occasionally, passive sumps without a fan may reduce […]
What is the main idea of drive theory psychology quizlet?
What is the main idea of drive theory psychology quizlet? Developed as an alternative to instinct theory, drive theory explains motivation as a process in which a biological need produces a drive that moves an organism to meet the need. For most drives this process returns the organism to a balanced condition, known as homeostasis. […]

How is sound waves measured?
How is sound waves measured? Sound energy travels in waves and is measured in frequency and amplitude. Amplitude measures how forceful the wave is. Frequency is measured in the number of sound vibrations in one second. A healthy ear can hear sounds of very low frequency, 20 Hertz (or 20 cycles per second), to a […]

Why thick wires are used in transformer?
Why thick wires are used in transformer? When a transformer is in operation, there are ac currents in primary and secondary coils. This is the most important for the high current winding (the secondary coil of a step-down transformer). Thick copper wire is used for this winding, because thick wire of low resistivity has a […]
What do the rows mean on a periodic table?
What do the rows mean on a periodic table? Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels. How do you identify […]
