A camcorder has a power rating of 16 watts. If the output voltage from its battery is 9 volts, what current does it use?
Sphinxa [80]
Because of the parameters that we are given in the question, the right current formula that should be used for this physics problem is:
I = P/V
Where:
I = Current
P = Power  and 
V = Voltage
From the question, we are told that:
P = 16 W
V = 9 V
Thus, current = P/V = 16/9 = 1.78
Therefore, The current used by the camcorder is 1.8 Amphere.

Select all that apply.
Gre4nikov [31]
Tasting or touching solutions to identify whether it is an acid or a base is something that you should always avoid since it can be dangerous and, in some cases, deadly.

<span>Phenolphthalein is typically used to test the pH level of a solution. Since you can determine whether a solution is an acid or a base by identifying the pH level, this is one of the correct answers.

</span>However, the question says to "select all that apply," so let's also check the last option, litmus paper.

Litmus paper is commonly used to identify whether something is an acid or a base. When blue litmus paper is exposed to an acid, it turns red. When red litmus paper is exposed to bases, it turns blue.

This means that the answers you should select are both litmus paper and <span>phenolphthalein.

Hope this helps!</span>
