A nurse needs to inject liquid medicine into your body by exerting a 2N force onto a hypodermic syringe. If the crossectional area of the barrel of the syringe is 0.05 m and the syringe's needle is 0.0025 m , with how many newtons of force does the medicine come out from the needle into your body? What principle do you use in this problem? O 1.0 N, Achemides principal O 0.1N, Bernoulli principal O 0.1 N, Pascal principal 0.005N, Pascal principal K
