Plss ! the models below represent nuclear reactions. the atoms on the left of the equal sign are present before the reaction, and the atoms on the right of the equal sign are produced after the reaction. model 1: atom 1 + atom 2 = atom 3 + energy model 2: atom 4 = atom 5 + atom 6 + energy which of these statements is most likely correct about the two models?

a. both models show reactions which produce energy in the sun.

b. both models show reactions which use up energy in the sun.

c. model 1 shows reactions in the nuclear power plants and model 2 shows reactions in the sun.

d. model 1 shows reactions in the sun and model 2 shows reactions in a nuclear power plant.

Suppose a suitcase has a mass of (m) 30 kg and a net force (n) of 10 kg*m/s. what is the acceleration rate of the suitcasein m/s? show your work to support your answer

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.
