Um corpo de massa 40Kg está submetido a ação de duas forças de 6400N e 4000N , qual será o valor da aceleração: se as forças tem a mesma direção e o mesmo sentido? E se as forças tem a mesma direção e sentidos contrários? De acordo com a Segunda lei de Newton (Fr=m. a), em qual alternativa o valor da aceleração nos seguintes casos está correto respectivamente? * 10 pontos
260N e 60N
100N e 160N
60N e 260N
160N e 100N
260N e 100N

7.study the scenario. a small container of water with a low temperature is poured into a large container of water with a higher temperature. which choice correctly explains what happens to the thermal energy of these systems? the smaller container of water has more heat and thermal energy than the larger container. some heat and thermal energy is transferred to the larger container of water. the larger container of water has more heat and thermal energy than the smaller container. some heat and thermal energy is transferred to the smaller container of water. the larger container of water has more thermal energy and some of that energy is transferred to the colder water in a process known as heating. the smaller container of water has more thermal energy than the larger container, and some of that energy is transferred to the warmer water in a process known as heating.
