A test tube with less water has a higher pitch because the vibration frequency of the water-air system is higher when there is less water present. This leads to a higher frequency of sound waves produced, resulting in a higher pitched sound.
A glass with less water will make a higher pitch when tapped, while a glass with more water will make a lower pitch. This is because the amount of water affects the frequency of vibrations produced by the glass when hit.
by water being placed into the bottle and then, when you launch your rocket, the rocket will spin (if it has at least 2 fins) and the water will spurt out and make the rocket go higher in the air. (Tip:the more it spins,the higher it will fly)
Fat is less dense than muscle and bone, causing fatty tissues to float better in water than lean tissues. This is due to fat being less compact and therefore more buoyant. Conversely, lean individuals with higher muscle mass may sink more easily in water due to their higher density.
Entropy is the measure of disorderness. Hot water --> more energy --> less stable --> more disorderness (than Cold water). Therefore, Entropy of Hot water is greater than that of Cold water.
Less.
diffuse towards area with more water . diffusion happens where it is from higher concentration to lower concentration . so more water of course higher concentration , less water of course lower concentration . this is what i think . but don guarantee correct answer .

Very salty water is more dense than water with less salt because the dissolved salt molecules increase the mass of the water. This higher density causes the salty water to sink below less salty water.
Reducing the mass of a rocket helps it achieve higher speeds, travel further, and carry more payload. This is because a lighter rocket requires less fuel to reach its destination, making it more efficient and cost-effective. Additionally, lower mass results in improved maneuverability and less strain on launch infrastructure.
Water is more dense than oil. This is because water molecules are more compact and tightly packed together, leading to a higher density compared to oil molecules which are more spread out and less compact.
it can be more or less buoyant be having more or less mass.i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.
Yes as it control the dirctions of the rocket.
Fat is less dense than muscle and bone, causing fatty tissues to float better in water than lean tissues. This is due to fat being less compact and therefore more buoyant. Conversely, lean individuals with higher muscle mass may sink more easily in water due to their higher density.
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
