Answer : 
Explanation :
Given that,
Charge of particle 1 = 
Distance x = 6 cm
Charge of particle 2 = 
Distance x = 27 cm
Total distance = 
Particle 1 is at (6,0) and particle 2 is at (27,0) .
Therefore, midway (16.5, 0)
Now, 
Formula of electric field
Now, the the electric field due to particle 1
Similarly, the electric field due to particle 2
Resultant Electric field
Hence, this is the required answer.
Well we know the hypotenuse of the triangle which is 253 m. And we know the angle of the triangle which is 55.8 degrees. So we want to find y. And to find y we use sin. And sin is a ratio, the ratio of the opposite leg, and hypotenuse. So sin(55.8) = y/253. Now we solve for y by multiplying both sides by 253. And finally we get 209.25 as the length of the y component.
You need to check the temperature of food being stored in a temperature-controlled environment every four hours. The process of changing a space's temperature is called temperature control.
Cooking food alone may not be enough to avoid food poisoning, though, if the bacteria in food are allowed to grow to large numbers. When the temperature is between 5°C and 63°C, bacteria can grow. The risk zone is the range between 5°C and 63°C.
Temperature control is a process where the passage of heat energy into or out of a space or substance is adjusted to achieve the desired temperature. This process involves measuring or otherwise detecting changes in the temperature of the space (and all of the objects contained therein) or of the substance.
