I strongly believe that it is C just because this could not actually occur so the only thing that could happen is that she didn't talk as quietly as she thought she did.

Hope I helped!!!!

Explanation :

Sarah and Maria made a telephone using two cans and a string. It was a very long string. Maria went upstairs in her house and Sarah stayed downstairs. Maria spoke softly into the can. "I can hear you!' Sarah said back.

We know that the sound wave is a longitudinal wave. It requires a medium to travel. When Maria spoke softly into the can, the air present in the surrounding helps the sound wave to travel in the form of compression and rarefaction.

So, the correct option is (C) " Sound waves travel through solids like the string ".

Resistors in parallel together contain less resistance than resistors in series together. Create an analogy to explain this phen
Naddika [18.5K]
An analogy to explain this phenomena is the traffic explanation: Imagine you are in rush hour of traffic in a major city. Now imagine that all the traffic is only on one lane instead of being spread out on all six lanes. With more paths, there is less resistance to flow.

Your answer is: Imagine you are in rush hour of traffic in a major city. Now imagine that all the traffic is only on one land instead of being spread out on all six lanes. With more paths, there is less resistance to flow. 

Have an amazing day mate!

a car takes off from rest and covers a distance of 80m on a straight road in 10s.calculate the magnitude of its acceleration
olasank [31]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

Here's the solution :

Let's find the final velocity :

  • \dfrac{displacement}{time}

  • \dfrac{80}{10}

  • 8 \:  \: ms {}^{ - 1}

Initial velocity (u) = 0 (cuz it started from rest)

Final velocity (v) = 8 m/s

Time taken (t) = 10 sec

now, we know that :

  • acceleration =  \dfrac{v - u}{t}

  • \dfrac{8 - 0}{10}

  • \dfrac{8}{10}

  • 0.8 \:  \: m {s}^{ - 2}

Acceleration = 0.8 m/s²
