$D.$ Acids and bases are good conductors of electricity
$5.$ Which safety precaution must Rashmi follow while doing this activity$?$
$A.$ Wear boots
$B.$ Wear goggles
$C.$ Wear headphones
$D.$ Wear rubber gloves
$6.$ Will an electric device work if we place the positive terminal of a battery towards the negative point of the device? Explain your answer.

✓

Answer

$4. D.$ Acids and bases are good conductors of electricity
$5. D.$ Wear rubber gloves
$6.$ Mentions that the electric device will not work as there will be insuficient current low from the battery to the device.
For example:
● The electric device will not work as there will be insuficient current low from the battery to the device.
