(FCMSCSP) — Em 1687, em sua famosa obra Princípios Matemáticos da Filosofia Natural, o físico inglês Isaac Newton formulou três leis que constituem a base para a compreensão dos comportamentos dinâmico e estático dos corpos materiais, tanto na Terra como no espaço. A primeira é a lei da inércia, a segunda lei é a que relaciona a força resultante que age sobre um objeto com a aceleração que ele adquire e a terceira é a lei da ação e reação. Um vaso em repouso sobre uma mesa é um exemplo A da primeira lei, apenas. B da segunda e da terceira leis, apenas. C da terceira lei, apenas. D da primeira e da segunda leis, apenas. E das três leis.

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
