I’m a personal problem with no clear solution;
New coins, bills, or stamps from a mint institution;
A magazine’s print of this month’s distribution;
Or policy topic, like guns or pollution.

Who am I?

UPDATE: Riddle solved by Asher. See comments for answer.

I’m a cord on a bomb that is lit to ignite;
For two cells to combine, or two atoms unite;
In a circuit, I melt when the current’s not right;
And I’m short on a person who’s ready to fight!

Who am I?

I’m a one-day triathalon, grueling and long;
I’m a weight-lifter’s magazine, read by the strong;
I’m a digital Timex; a Black Sabbath song;
And a metal-clad hero, out righting each wrong.

Who am I?

I block noise in your ears if you’re using a pair;
I am put into outlets for charging things there;
I’m for closing off drains; I am transplanted hair;
And the mentions for brands to make viewers aware.

Who am I?

I’m a hunting companion who helps you find game;
An artillery crewman whose job is to aim;
As a stick, I show charts; as a laser, the same;
A computer screen arrow; or sister act name.

Who am I?

As a typewriter, Smith has been merged with my brand;
I’m a Mexican beer; an Italian pop band;
I’m a tower for Becket; Rapunzel’s home land;
And surrounding the sun, I’m the plasma that’s fanned.

Who am I?

I am pulling the strings of a banjo or bass;
Remove hair from your eyebrows when grooming your face;
To take feathers off chickens; pull fruits from their place;
And when faced with a challenge, the courage to brace.

Who am I?

I’m a single from Ne-Yo; an airport in Spain;
A satirical magazine to entertain;
In the States, I am angry; in Britain, insane;
And deterrent from nukes when you’d both feel the pain.

Who am I?

I’m municipal trash and a landsite I fill;
To be thinning away when you’re hungry or ill;
To spend money on nothing; to callously kill;
I’m to throw away food; or to carelessly spill.

Who am I?

UPDATE: Riddle solved by Asher. See comments for answer.

I’m a person in stories you’ve read or have heard;
I’m that strange new acquaintance with manners absurd;
I’m a letter in English; in Chinese, a word;
And the values that lead to behavior preferred.

Who am I?
