Wave speed = frequency * wavelength
Wave speed = 1.80 * 0.30
Wave speed = 0.54 m/s
Answer The ethanol is stabilized by strong intermolecular forces between the molecules.wer:
Explanation:
During the phase change represented by the heat of fusion the temperature does not change. The molecules in the liquid state has a higher degree of freedom but are stabilized by the strong hydrogen bonding requiring a larger into of energy to separate the molecules than the heat of fusion.
<span>(4) The dissolving of the LiBr(s) in water is an exothermic process</span>
Answer:
The foam board has a larger gravitational force but it also has a very large air resistance force. The net (total) force on the foam board will give it a smaller acceleration than paper.
Explanation:
The air molecules get knocked away and take some of the kinetic energy away from the object, which makes the object slow down
The answer is 1. Radiation
