6. Los amortiguadores de un automóvil viejo con masa de 1800 kg están gastados. Cuando una persona de 780 N se sube lentamente al auto en su centro de gravedad, el auto baja 5.0 cm.
Cuando el auto, con la persona a bordo, cae en un hoyo, comienza a oscilar verticalmente en
un movimiento armónico simple. Considere el auto y la persona como un solo cuerpo (una sola
masa) en un solo resorte y calcule (a) el periodo y (b) la frecuencia de oscilación. (10 puntos)

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.

If forces acting on an object are unbalanced. true or false

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!
