The amount of heat needed to increase the temperature of a substance by
![\Delta T](https://tex.z-dn.net/?f=%5CDelta%20T)
is given by
![Q= mC_s \Delta T](https://tex.z-dn.net/?f=Q%3D%20mC_s%20%5CDelta%20T)
where m is the mass of the substance, Cs is its specific heat capacity and
![\Delta T](https://tex.z-dn.net/?f=%5CDelta%20T)
is the increase of temperature.
If we re-arrange the formula, we get
![C_s = \frac{Q}{m \Delta T}](https://tex.z-dn.net/?f=C_s%20%3D%20%20%5Cfrac%7BQ%7D%7Bm%20%5CDelta%20T%7D%20)
And if we plug the data of the problem into the equation, we can find the specific heat capacity of the substance:
Answer:
Since binary is only 1 and 0, you can use a flashlight to display something similar to Morse code (see explanation below)
Explanation:
In binary, 1 means "on" and 0 means "off". A way you can use visible light is through turning on and off a flashlight. If the flashlight is turned on, it would represent a 1. If the flashlight is turned off, it would represent a 0. To make the message easier and more accurately understood for the receiver make sure to flash the lights in a consistent pattern (ex. each flash lasts no longer than half a second, one second between each digit, etc.)
For example, let's say you're trying to send the message "11001"
on on off off on
0 1 2 3 4 5 <em>Numbers represent seconds</em>
As you can see above the message starts at 0 seconds. Between 0 and 1 seconds the flashlight is turned on once. Between 1 and 2 seconds the flashlight is turned on again, Between 2 and 3 seconds as well as 3 and 4 seconds the flashlight is not turned on at all. And finally between 4 and 5 seconds the flashlight is turned on.
