Tres cargas puntuales se encuentran a lo largo del eje x. La carga positiva q1 = 15,0 mC está en x = 2,00m, la carga positiva q2 = 6,00 mC está en el origen y la
fuerza neta que actúa sobre q3 es cero. ¿Cuál es la coordenada x de q3?

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
