If one sound wave has twice the amplitude of another the first sound is​
aleksley [76]

Answer:

if one wave has a negative displacement, the displacements would be opposite each other, so the displacement where the waves overlap is less than it would be due to either of the waves separately.

-causes a moment where the net displacement of the medium is zero. energy of waves hasn't vanished, but it is in the form of the kinetic energy of the medium

-then both emerge unchanged

How do you find total displacement
Monica [59]

That's actually a lot easier than finding total <u><em>distance.</em></u>

To find displacement, you only have to know where the trip started from, and where it ended.   It doesn't matter what route was followed to actually travel from the start to the finish.  The displacement is the straight-line distance and direction between those two points.

When a constant force acts upon an object, the acceleration of the object varies inversely with its mass 2kg. When a certain con
BARSIC [14]

Answer:

The acceleration of the second object is 4 m/s².

Explanation:

Given that,

when the a constant force acts upon an object, the acceleration varies inversely with its mass .

mass\propto \frac{1}{acceleration}

We can rewrite the equation as

\frac{m_1}{m_2}=\frac{a_2}{a_1}

When an a certain constant force acts upon an object with mass 2 kg , the acceleration of the object is 26 m/s².

Here, m_1 = 2 kg, a_1 = 26 m/s²,m_2 = 13 kg and a_2=?

\frac{m_1}{m_2}=\frac{a_2}{a_1}

\frac{2}{13}=\frac{a_2}{26}

\Rightarrow \frac{a_2}{26}= \frac{2}{13}

\Rightarrow {a_2}= \frac{2}{13}\times 26

\Rightarrow a_2=4 m/s²

The acceleration of the second object is 4 m/s².
