The following questions will you learn to apply the impulse-momentum theorem to the cases of constant and varying force acting along the direction of motion. first, let us consider a particle of mass m moving along the x axis. the net force f is acting on the particle along the x axis. f is a constant force. part a the particle starts from rest at t=0. what is the magnitude p of the momentum of the particle at time t? assume that t> 0. express your answer in terms of any or all of m, f, and t.

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
