One of the many unique properties of water is that its solid form (ice) is less dense than its liquid form. most substances become more dense when in solid form, because their molecules are more tightly compact. why is this property of water so important to life on earth? a) nutrients are easily dissolved in water to allow distribution b) surface water freezes and insulates the water below for marine life c) it allows water to travel up plants to distribute water to stems and leaves d) ocean water temperature doesn't fluctuate as much due to its high specific heat

Aphids are tiny insects that feed on plants. ladybugs are to plants because they eat aphids. which type of organism are aphids in this scenario? co decomposers predators prey producers

Acceleration is a direct result of a.) balanced forces b.) unbalanced forces c.) gravity d.) velocity

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
