Dos masas de 18 kg. están ligadas por una cuerda como lo indica la figura. la mesa esta pulida y la polea no presenta rozamiento

calcular la aceleración del sistema y la tensión de la cuerda

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!

When can a theory be modified if a new type of technology allows for new observations that raise new questions? a-immediately, while the questions about the theory are being asked b-after new hypotheses related to the theory are tested in experiments c-only after the new observations disprove all parts of the theory d-while scientists begin to think about how the theory could improve
