If the area of a square is 81 square meters, how many meters long is each side

Chemistry
1 answer:
Anarel [89]3 years ago
8 0
Area is length times width, so you would want to undo that. Since this is a square and the sides are equal, you would find the square root of 81 which is 9. Each side of the square is 9 meters

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
