Answer:
We use the relationship F = m x a, adapted for Weight: W = m x g
Weight is the force, m is the mass and g is the acceleration of gravity. Take an example: you are 100 kg made up of 70 kg of body mass and 30 kg of space suit. Your weight on the Moon would be 100 kg x 1.62 m/s^2 = 162 Newtons (weight force).
On Earth that would be a Weight of 100 kg x 9.81 m/s^2 = 981 Newtons.

Explanation:
Given
COP= 60 % of carnot heat pump
![COP=\frac{60}{100}\times \frac{T_H}{T_H-T_L}](https://tex.z-dn.net/?f=COP%3D%5Cfrac%7B60%7D%7B100%7D%5Ctimes%20%5Cfrac%7BT_H%7D%7BT_H-T_L%7D)
For heat added directly to be as efficient as via heat pump
![Q_s=W](https://tex.z-dn.net/?f=Q_s%3DW)
![COP=\frac{Q_s}{W}=\frac{60}{100}\times \frac{T_H}{T_H-T_L}](https://tex.z-dn.net/?f=COP%3D%5Cfrac%7BQ_s%7D%7BW%7D%3D%5Cfrac%7B60%7D%7B100%7D%5Ctimes%20%5Cfrac%7BT_H%7D%7BT_H-T_L%7D)

Answer:
"Both students are correct. When light is traveling through small openings, solids, liquids, gases, or a vacuum, it behaves like a wave. When it interacts with matter, it acts like a stream of particles."
Explanation:
just got it right
14 g is the solubility per 100 g water, since it is difficult to read the graph.
<span>Then, in 130 g H20 the solubility would be 14 g KNO3/100 g H2O x 130 g H2O = 18 g KNO3 </span>
<span>The question asks how much crystallizes. </span>
<span>Initial 34.0 g minus 18.0 g still dissolved = 16.0 g crystallizes.</span>
