10 are left.
A third of 15 is, 15 divided by 3 = 5
subtract 5 (the number of crows shot) from 15 = 10
There would be 10 crows left on the fence after the farmer shoots a third of the initial 15 crows.
A fence.
If you mean a chain link fence or picket fence, sound will go right through it. If you mean a fence you can't see through, one standing 6 or so feet high with no gaps, it can reduce the sound, but not prevent it from escaping entirely.
No, it is not possible to touch an electric fence without receiving a shock.
Dropping the picket fence from a higher height above the photogate would not change the parameters you measured, assuming the initial velocity of the picket fence remains constant. The time it takes for the picket fence to pass through the photogate and the acceleration due to gravity acting on the picket fence would remain the same. The height from which the picket fence is dropped would only affect the initial velocity of the picket fence, not the parameters being measured.
None of the crows will be left.They all will have flown away.

3 check the fence posts...
Fifteen feet from a fire hydrant is fifteen feet from a fire hydrant.. Just the same as fifteen feet from the fence..
The electric fence!
There are eight crows sitting on the telephone wire.
You find it caught on the fence of the farmer's brother.
There are 13 sheep remaining inside the fence.
The answer is "none", all birds will fly away
the sides of the fence are parallel to the rows of crops.
One is because the farmer needs to allow the grass to regain control and grow taller while the cattle were moved to the already regained pastures. Another might be because a fence was down and the farmer didnt want the cows to get out of the fence. There could have been a sick cow and the farmer didnt want the hole herd to get the disease These are some of my reasons
Yes, this is in the realm of possibility and in fact happens. It will not be a dangerously high voltage induced into the fence but you will be able to feel it. Proper grounding of the fence will eliminate the condition.
