Explanation:

Volume of 10 coins = 100ml - 75ml = 25ml

Volume of 1 coin = 25ml / 10 = 2.5ml

The average volume of each coin is 2.5ml.

Alexus [3.1K]

firstly you get your acceleration with the formula, a=v-u/t. Then you use the formula for kinetic energy 1/2mv^2

then you can finally get the answer for power by dividing your previous answer by the time

bezimeni [28]

Answer:

1904 m

Explanation:

\pink{\frak{Given}}\begin{cases} \textsf{ You scream after seeing a rattle snake  .}\\\textsf{Scream is heard after 11.2 s .} \end{cases}

Here we need to find out the depth of the canyon . When you will scream after seeing a snake , the sound produced will travel till the end of the canyon and after hitting the end , it will travel back to you .

  • So if the depth of the canyon is d (say) , then the total distance travelled by the sound wave will be d + d = 2d .

And we know that the speed of the sound is approximately 340m/s in air , so we can use the formula distance = speed * time to calculate the depth of the canyon . So ,

\sf \longrightarrow Distance = (Speed)(Time) \\

\sf \longrightarrow 2d = 340m/s * 11.2 s\\

\sf \longrightarrow d = \dfrac{340m/s * 11.2s}{2} \\

\sf \longrightarrow \boxed{\bf Depth_{canyon}= 1904m }\\
