work, power, energy

What is power? power is the rate at which work is done. What is wavelength? Wavelength is the distance from any point on a wave to the next identical point on the same wave. What is frequency? Frequency is the number of waves that pass a point in a given amount of time.
If 26W of power is produced in 15 seconds, how much work is done? W=PxT W= 26x15 W=390J What is a longitudinal wave? A longitudinal wave is when energy is transferred from one object to another. What is a compression? A compression is the direction in which waves travel.
What is work? Work is the use of force to move an object some distance. What is a trough? A trough is the points where the wave is lowest. What is amplitude? Amplitude is measured of how far particles in the medium move from their rest position.
If 78J are produced in 6 seconds, how much power is being done? P=W divided by T P=78J divided by 6sec P=13 How many different types of waves are there? 4. longitudinal, transverse, mechanical, and electromagnetic waves. What are the materials that a medium can travel in? Solid, liquid, or gas.
Can wavelength be measured from one crest to a trough? No, wavelength is measured from one crest to another crest or one trough to another trough. What are Hertz? 1 hertz is equal to one wavelength per second. What is the wavelength if each crest is 12ft long and troughs are 14ft long? Wavelength= 12=14=12 wavelength= 38ft long.
What is a crest? A crest is the point where the wave is highest. What is wave speed? Wave speed is the speed that waves travel. What is a transverse wave? A transverse wave is when springs coils move up and down as the wave passes.
What are mechanical waves? Mechanical waves are waves that require a medium. What is a wave? A wave is a disturbance that travels through a medium. What is force? Force is a push or pull exerted on an object on order to change the motion of the object.
If one hertz = one wavelength per second then how much wavelength is in seven hertz? Wavelength= 7 per second also. P=40 watts W= 2,000 Joules T? T= W divided by P T=2,000 divided by 40 T=50 seconds P=226 watts T=23 seconds W=? W=PxT W=226x23 W=5,198J
What is a medium? A medium is the material through which a wave can travel. What is rarefaction? Rarefaction is the direction in which an object is disturbed. What are electromagnetic waves? Electromagnetic waves are traveling of 1 energy source to another.
