Answer:
salt. (I think)
Explanation:
they neutralize each other and often this results in salt being formed and leftover
Explanation:
Hey there!!
Here,
Weighs = 65n
Gravity = 10n
We know that,
weighs = mass × gravity.
65 = m × 10

Therefore the mass is 6.5 kg.

Answer:
Both sound waves will travel at the same speed.
Explanation:
The speed of sound depends only on the density and the elastic properties of the medium it is travelling through, the mathematical relation is
,
where
is the bulk modulus<em> (a measure of how much a material will compress under a certain pressure)</em>, and
is the density of the medium.
Since the frequency of a sound wave does not change the properties of the medium it is travelling through, every frequency will have the same speed through a certain medium.
Hence, a 5,000 Hz and a 40-Hz sound wave will have the same speed through steel.
