There are exactly three ways that could happen:
1). The container was heated, and the gas inside it got warmer.
2). Some part inside the container moved somehow, and made
the inside volume smaller, so the gas got scrunched into a
smaller space.
3). Somebody pumped some more gas into the container, so
a greater amount of gas had to live in the same space.
I believe it is Acoustics, the real name for it would be like Reverberation. But go with Acoustics. :)
Answer:
The charge on the ball bearing 4.507 × 10^-8 C
Explanation:
From Coulomb's law
F = kq1q2/r²
make q2 the subject
q2 = Fr²/kq1
q2 = (1.8×10^-2 × 0.026²) ÷ (9×10^9 × 30×10^-9)
q2 = 4.507 × 10^-8 C
Answer:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
