A41.0 kg child swings in a swing supported by two chains, each 2.98 m long. (a) if the tension in each chain at the lowest point is 348 n, find the child's speed at the lowest point. m/s (b) what is the force exerted by the seat on the child at the lowest point? (neglect the mass of the seat.) n (upward)

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

Me with this and you will be marked brainliest

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
