A class of students is modeling how waves propagate through a medium. Each student in the class represents particle in the medium. An envelope represents the energy transferred by the wave. Which of the following scenarios would accurately model a wave propagating from one side of the room to the other?

Answers

Answer 1

Answer:

C: "The students pass the envelope from one student to the next until it travels across the room."

To quote ck12, "The particles of the medium just vibrate in place. As they vibrate, they pass the energy of the disturbance to the particles next to them, which pass the energy to the particles next to them, and so on."

A wave has a wavelength of 125 meters is move a distance of 300 m in 15s. What is its frequency? please help

Answers

   Frequency of any wave = (speed) / (wavelength)

   = (300m / 15s) / (125m)

   = (300m) / (15s x 125m)

   =    (300) / (15 x 125)    (m/s-m)

   = 0.16 / sec = 0.16 Hz .

Plz help.How do ions form electrically neutral compounds?

Answers

They form electrically neutral compounds because the number of captions (positively charged ions) is equal to the number of anions (negativley charged ions) These ions are held together by strong electrostatic forces of attraction.

how would your weight change on the surface of an earth sized planet whose mass was greater than earths? why?

Answers

Gravity=Gm1m2/r²
G=Gravitational constant
This equation describe the gravity between two objects, which is you and a planet.
if mass become greater, no matter of which object, the Gravity become bigger too.
So your weight will become greater.

lin is right but your mass does not change and your weight does.your weight changes because of the gravitational pull on earth comparing to another planet
