A particle of mass 23 g and charge 36 µC is released from rest when it is 59 cm from a second particle of charge −17 µC. Determine the magnitude of the initial acceleration of the 23 g particle. Answer in units of m/s 2 .

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.

Calculate a pendulums frequency of oscillation (in hz) if the pendulum completes one cycle in 0.5s.

The field lines around one end of a bar magnet are shown below based on the diagram, what can you conclude about the pole of the magnet? a.is a south pole because the field hnes spread out from this end b.a north pole because the field lines spread out from this end c.a nouth pole because the field lines enter the magnet at this end d.is a north pole because the field lines enter the magnet at this end
