52.10 Which best explains how and why scientific knowledge is continually expanded and improved?

The scientific process flows in one direction and finds only facts that support a scientist's original idea.

O The scientific process is cyclical so that new facts inspire questions that lead to new studies.

Once explanations are found to be true, they do not need to be questioned; then scientists can stop studying the

topic.

Once facts are found through experiments and observations, other scientists do not need to repeat the experiments.

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

Which process is represented by the pv diagram? a. the isobaric process b. the isovolumetric process c. the isothermal process d. the adiabatic process
