<u>D: Half</u>
We know that,
F = m.a, where F is the force, m is the object's mass and a is the acceleration.
In the first case, we observed that a1 = F/m.
In the second case, we observed that the mass has been doubled, so a2 = F/2m .
By the ratio of the two cases, we get
a1/a2 = F/m / F/2m
or, a1/a2 = 2
or, a1 = 2.a2
or, a1/2 = a2
Therefore, the acceleration gets <u>half</u> of it's original measurement.
<span>The last main subatomic particle to be discovered was the
antihelium-4. It was discovered on 2011
and it is measured and produces through the STAR detector. The Antihelium-4 was discovered accidentally
when an experiment was conducted. It is
also the first particle that was discovered by the means of experiment.</span>
The energy transferred by a sound wave is independent of its speed. However, the type of medium affects this due to the differences in the distances between particles in different media, i.e. sound travels faster through solids than gases as the solid particles are much closer together, so they collide more frequently allowing the sound to travel faster. Additionally, temperature affects the distances between particles in a medium, increasing them with increasing heat, causing slower sound travel. Therefore the answer is the third option.
