Un proyectil es disparado con una velocidad inicial de 250 . Encontrar: a) el ángulo del disparo para que el proyectil golpee a un blanco situado a 3000 m, sobre el mismo nivel; b) la altura máxima alcanzada.

Calculate the kinetic energy of earth due to its spinning about its axis. krot = j compare your answer with the kinetic energy of the orbital motion of earth's center of mass about the sun. assume earth to be a homogeneous sphere of mass 6.00 1024 kg and radius 6.40 106 m. the radius of earth's orbit is 1.50 1011 m.

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

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .
