Just has to be greater than or equal to 0... w and t can never be negative since taking the square root of a negative number yields an imaginary number which would mean imaginary current. Also the question states that w can't be zero but if T is zero than the current will be zero.
Well what grade are you in cause I’m also learning some of this stuff, I actually learned it before at t(e beginning of the year
If you mean like a method to solve it fast here I have 1 solution I usually use;
3x2.7
3x.7=2.1
3x2=6
Then in the question there is 1 number behind the decimal point so the answer should have 1 number behind as well.
=8.1
The answer is is 17x. I hope this helps
