Communicating results allows scientists to learn from each other's results.
true
false

True, scientists often talk to each other to figure out if their results were similar and what they could have done better.

Although, talking to other scientists does have risks, other scientists could copy your work and further better it.

So, your final answer is TRUE, sorry for the long answer, I needed to have a word count about 20 characters and then I got carried away! lol

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

at right angles to each other
