When waves travel through water, why do the moving water particles continue to return to their starting position? a. Waves trans
fer matter, but not energy. b. Waves transfer both matter and energy. c. Waves transfer energy, but not matter. d. Waves don’t transfer matter or energy.
<em><u>A wave is a transmission of a disturbance from one point to another. Wave involves transmission of energy from one point to another through a materials medium.</u></em>
<em><u>Waves may require or may nor require a material medium for transmission. </u></em>Those wave that do not require material medium for transmission are electromagnetic waves while those that require material medium are called mechanical waves.
<em><u>Mechanical waves</u></em> transfers energy through the vibration of particles of the medium through which the wave travels, while<em><u> electromagnetic waves t</u></em>ransfer energy through the vibration of electric or magnetic fields.
<em><u>Waves transfers energy from one point to another without moving matter.</u></em>
The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.
1 watt is 1 Joule per second. 240 watt would then be 240 joules per second. How many seconds are there in an hour? Current formula is P= IV , P is 240(not the power in an hour because the current is calculated in seconds), and V is 12V. Then you will get I, the current.
