inside a jar. What happens as air is removed from

jar?

0% 0%0%0%

1. Bell's pitch decreases

2. Electric circuit stops working

because electromagnetic

radiation cannot travel in vacuum

3. Bell's loudness decreasesbecause sound waves cannot

travel through a vacuum

4. Bell's loudness increases

because of decreased air

resistance
