Rasek [7]

Answer:- The wavelength is 1.36*10^1^2m and the right option is D.

Solution:-  Wavelength is inversely proportional to the frequency and the equation is:

\lambda =\frac{c}{\nu }

where, \lambda
 is the wavelength, c is the speed of light and \nu is frequency.

Frequency is 2.20*10^-^4Hz and the speed of light is 3.00*10^8\frac{m}{s} .

Since, 1Hz=1s^-^1

So, 2.20*10^-^4Hz=2.20*10^-^4s^-^1

Let's plug in the values in the equation:

\lambda =\frac{3.00*10^8m.s^-^1}{2.20*10^-^4s^-^1}

\lambda =1.36*10^1^2m

Hence, the right option is D) 1.36*10^1^2m .

Ethylene glycol is a compound used in automotive antifreeze. It is odorless, colorless, and toxic if ingested. Adding ethylene g
const2013 [10]

Answer: Andre. If it is used as an antifreeze, one would infer that it's freezing point is less than water.

Explanation:

The freezing point of ethylene glycol alone (100%) is -12.9oC. That is somewhat less than the freezing point of water but nowhere near the freezing point of water containing 70% ethylene glycol.
