I Can Sound a Gong

I’m in bowling and baseball,
For better or for worse,
On a match (but not the sporting kind),
I can sound a gong,
And I’m gone.

What am I?

Strike.

A strike in bowling is good. In baseball it’s good for the pitcher but not for the batter. You can strike a match to light it. When the clock strikes one a gong sounds and when you strike a paragraph, it’s gone.

Stars Awash in a Sheen of Light

Stars awash in a sheen of light
It calls out loud in vile delight.
Listeners endure in fright.
Vicious brute that reigns at night,
Evil whelped of heinous bite,
Renewed by wax, it regains might.
A leading way to slay the beast,
Get the hidden weapon thus released.

What is this describing?
Hint: The first letter of each line has a clue

A werewolf (vulnerable to silver bullets).

The Secret of the Chalk Emerald

A dear old relative passed away recently and her family gathered for the reading of the will. The final item was the Chalk Emerald, a priceless gem. The will bequeathed it to whoever determined where it was hidden. The only clue was it was in a cylinder surrounded by a thousand squares. A young lass of barely six immediately piped up saying she knew where it was hidden and she was correct. Where was the hiding place?

In a roll of toilet paper.

Mark suggested two alternative solutions: A cylindrical chimney or a well, the squares being the bricks. Although most bricks aren’t square, it’s conceivable I guess.

Debbie’s Dragster

Debbie starts driving her dragster from rest and constantly accelerates to 60 mph in 10 seconds. How far does she travel in those 10 seconds?

1/12 mile

Ten seconds is 1/6 of a minute and 1 minute is 1/60 of an hour, so 10 seconds is 1/360 of an hour.

If you graph her trip with the speed on the y-axis and the time on the x-axis, you get a triangle with height of 60 mph and width of 1/360 of an hour. To calculate the area of the triangle, you multiply 1/2 × 1/360 × 60 = 1/12.
