Brainlies ! 1. based on dalton's atomic theory, which of the following is true about all atoms of the same element? they have different masses. they have the same properties. they can be divided into molecules. they are composed of visible matter. 2. boron is to the immediate left of carbon in the same row in the periodic table. which of the following statements compares the radius and pull exerted by the protons of boron and carbon atoms? boron has a smaller radius and the protons in carbon exert a greater pull. boron has a larger radius and the protons in carbon exert a greater pull. boron has a smaller radius and the protons in carbon exert less pull. boron has a larger radius and the protons in carbon exert less pull.

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.
