3241004551 [841]

Answer: I= 0.583A

R=205.83ohms

Explanation: Power= I*V

Where I= current and V = potential difference

I=P/V

I= 70/120

I=0.583A

To find resistance

Using ohms law

V= IR

R=V/I

R= 120/0.583

R= 205.83ohms

Parallax error occurs when the observer records data when he/she is at an angle to the event he/she is observing. Where do you t
kompoz [17]

Answer:Orient your line of sight directly above the measurement markings.

Explanation: parallax error is a type of systematic error that occurs when an observer views a measurement marking at a wrong angle. This causes a noticeable disparity in results obtained. Therefore the best way to prevent this error is to view and record the data from the correct angle. This can be obtained by:

-Place the measurement device on its edge so it is level with the object being measured.

-Seek out the finest possible edge of the measurement device, or use a device with finer edges.

In conclusion, ask other observers to also take the reading and get an average of their results. It can help cancel out parallax error results.

The answer would be b., individualism. Femininity is obviously out the picture and decentralization means "The transfer of authority from central to local government. and collectivism is "<span>the practice or principle of giving a group priority over each individual in it." And since the statement says "...my teacher will recognize MY efforts!" and not OUR efforts, then it isn't collectivism.</span>
