Okay, lets start from the beginning. I'm going to assume the worksheet means/is asking how long/short the sound would be from the object. So...
1) Light bulb - Long
2) Bricks/Cinderblocks - Short
3) Hair Dryer - Long
4) Swimming - Long
5) Whistle - Could potentially be both, but most likely short.
6) Crying/Wailing - Long
7) Fencing - Could potentially be both, but most likely short.
8) Grilling - Could potentially be both, but most likely long.
9) Flies/Bug - Could potentially be both, but most likely long.
10) Smiling- Short
11) Eating Pie/Pie in General - Could potentially be both, but most likely short.
12) Jumping off a cliff. Could potentially be both, but most likely long.
Hope that helps.
