Explanation:

1 kJ = 238.85 cal and

1 cal = 0.004187 kJ

so it will be 78.9×238.85 = <em><u>1</u></em><em><u>8</u></em><em><u>,</u></em><em><u>8</u></em><em><u>4</u></em><em><u>4</u></em><em> </em>calories

78.9 Kilojoules (kJ) = 18,844 Calories (IT) (cal)

Why do you think foods and drinks are stored in aluminum cans and not iron cans
Maslowich
Aluminum can preserve food and drinks longer than iron can. If oxygen combines with the iron the iron will rust and the food or drink inside will not be good to eat anymore and you will have to waste it.

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F.
anyanavicka [17]
The initial equation is <span>F = (9/5)C + 32. We are asked to get the formula to solve for C. So the idea here is to isolate C on the other side, where F is currently located. 

1. Subtract 32 on both sides. 
2. Divide 9/5 on both sides. 

You should get </span><span>C = 5 over 9(F – 32) as your answer. </span>

If a 12-volt battery produces a current of 20 amps, what is the resistance?
mixas84 [53]

Answer:

0.6 Ω

Explanation:

From the question given above, the following data were obtained:

Voltage (V) = 12 V

Current (I) = 20 A

Resistance (R) =?

From Ohm's law,

V = IR

Where:

V => is the voltage

I => is the current

R => R is the resistance

With the above formula, we can obtain the resistance as follow:

Voltage (V) = 12 V

Current (I) = 20 A

Resistance (R) =?

V = IR

12 = 20 × R

Divide both side by 20

R = 12 / 20

R = 0.6 Ω

Thus the resistance is 0.6 Ω
