True.
A zero on the Kelvin temperature scale is also know as Absolute Zero because that is when the atom(s) have literally no kinetic energy.
Answer:
The SI unit of acceleration is metres/second2 (m/s2).
Explanation:
hope this helps
Explanation:
The depth d of the water (in meters) and the velocity v of the wave (in meters per second) are related by the equation as:
We need to find the water's depth is a a wave formed in shallow water has a velocity of 4.5 m/s.
So,
Hence, if the wave formed in shallow water has a velocity of 4.5 m/s, then the water's depth is 0.459 m.
Answer:
The speed of sound in air is lower compared to in solids and liquids.
Explanation:
Sound is a wave that can be generated by a vibrating body. Its speed through different media differs due to the nature of the media.
Since the molecules of solids are closely packed, sound can be easily transferred from one molecule to another at a faster rate. Thus, the high speed of sound in solids.
In liquids, the molecules are not as closely packed as solids. So that the speed of sound though liquids is lower compared to that of solids. Gases has its molecules farther apart, thus making the speed of sound through it the lowest compared to solids and liquids.
Therefore the sound of the batter hitting the ball is heard latter, due to its lower speed through the air.
The correct answer is letter D. A study area. <span>According to the information in your study unit, the location that requires the highest illuminance is the study room because it is the place the students can stay to study. The more brighter the place is, the more people are using that area.</span>
