Batteries often convert chemical energy directly to electrical energy.
From the experiment, the constructed conclusion was that;
- The Two different gases with different properties are made from adding energy from a battery to water.
- The particles that make up these different gases is different from each other. They are different than the ones that were made from heating water.
- The matter that is composed of substances have to originate from matter that made up some of the original water particles.
When energy from a battery is added to
water, two streams of gas bubbles is said to be produced. Then a lit match is put into trapped gas from these two sources, one pops
and the other glows brighter.
The study was to test the flammability of gases produced by providing energy to water with electricity.

Answer:
the maximum current is 500 A
Explanation:
Given the data in the question;
the B field magnitude on the surface of the wire is;
B = μ₀i / 2πr
we are to determine the maximum current so we rearrange to find i
B2πr = μ₀i
i = B2πr / μ₀
given that;
diameter d = 2 mm = 0.002 m
radius = 0.002 / 2 = 0.001 m
B = 0.100 T
we know that permeability; μ₀ = 4π × 10⁻⁷ Tm/A
so we substitute
i = (0.100)(2π×0.001 ) / 4π × 10⁻⁷
i = 500 A
Therefore, the maximum current is 500 A
From the travel car, it would look like you were running. If you were watching from the top of a tree, you would see the train moving.
