Answer:
The amount of energy that would be released is equal to 4182 Joules.
Explanation:
Total amount of coke = 2 kg = 2000 g
1 calorie per gram is equal to 4.184 Joules of energy
4.184 J/gC*2000g = 8368 J
1 food calorie is roughly equal to 4186 J
8368 - 4186
Therefore, the amount of energy that would be released is equal to 4182 Joules.

Answer:
current forms when electromagnetic waves strike a semiconductor, removing some of its electrons.
Explanation:
Answer:

The Magnitude of electric field is in the upward direction as shown directly towards the charge
.
Explanation:
Given:
- side of a square,

- charge on one corner of the square,

- charge on the remaining 3 corners of the square,

<u>Distance of the center from each corners</u>


∴Distance of center from corners, 
Now, electric field due to charges is given as:

<u>For charge
we have the field lines emerging out of the charge since it is positively charged:</u>

<u>Force by each of the charges at the remaining corners:</u>

<u> Now, net electric field in the vertical direction:</u>


<u>Now, net electric field in the horizontal direction:</u>


So the Magnitude of electric field is in the upward direction as shown directly towards the charge
