In order to maximize the thermal effects of ultrasound, the treatment area should be no more than three (3) times the size of the soundhead surface. True False

Question 2 (2 points) Why is Ohm's Law relevant? Ohms law is extremely important to the world of electrical circuits and components but is not suitable for every electrical circuit and application. There are certain requirements that a circuit and electrical component should meet to ensure that Ohms law is applicable. Ohms law can be used to calculate the required value of Voltage or components within a circuit, it can also work out the amount of current that flows in an electrical circuit when resistors can be measured across electrical components such as voltage. Ohm's Law is not relevant Ohm's Law is only used in a DC circuit.

Question 21 Repeatedly tap the side of a drinking glass with a spoon as you fill the glass with water and the pitch of the sound decreases. C increases. remains relatively constant.

How can water vapor become ice? Water vapor can become liquid water through the release of heat energy,and then become ice through the release of more heat energy. Water vapor can also become ice directly through the release of heat energy. Water vapor can become liquid water through the release of heat energy,and then become ice through the release of more heat energy. Water vapor cannot become ice directly through the release of heat energy. Water vapor can become liquid water through the addition of heat energy.and then become ice through the addition of more heat energy. Water vapor can also become ice directly through the addition of heat energy. Water vapor can become liquid water through the addition of heat energy.and then become ice through the addition of more heat energy. Water vapor cannot become ice directly through the addition of heat energy.
