In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.

Sound waves transfer energy by causing successive compressions and rarefactions in the particles of the medium without transporting the medium particles themselves.

Explanation:

Sound in solids can also manifest as transverse waves, causing crests and troughs in the propagation medium. Waves can be characterized by two basic parameters: amplitude and frequency. Focusing on a single point vibrating in a medium excited by a sound wave, amplitude is the maximum distance traveled by the vibrating point relative to its rest position. Taking a snapshot of a propagating sound wave at any instance shows consecutive compressions and rarefactions, regions in which the medium material is compressed together and spread widely apart, respectively. The distance between the centers of two successive compressions or rarefactions is the wavelength of the wave. The frequency is the inverse of the wavelength, so the larger the frequency, the smaller the wavelength. Having a higher frequency makes the wave have a larger number of more closely-grouped compressions and rarefactions as it propagates. As the amplitude and frequency of the wave increase, the energy transferred by the propagation of the wave also increases. Extremely short but low-amplitude ultrasonic waves can be used to heat polymer materials and weld them together.

cell differentiation is how generic embryonic cells become specialized cells. this occurs through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.

hi there!

out of the two, (b) precision would be more reasonable. however, both a and b could be pretty reasonable.

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
