rewona [7]4 years ago
4 0

I believe the correct answer to this question is:

“Mixtures”

 

By definition, mixtures are combination of substances which are not really chemically combined and hence separable by physical means. There are two types of mixtures, homogeneous and heterogeneous, both are also separable by physical means.

<span>This is as opposed to Compounds which are chemically bonded and cannot be separated by physical means.</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
