What is system thinking?

To break a chemical bond, particles need to collide with a certain amount of a]energy. b]atoms. c]molecules. d]chemicals.

An athlete pulls handle a to the left with a constant force of p = 125 n. knowing that after the handle a has been pulled 30.25 cm its velocity is 3.2 m/s, determine the mass of the weight stack b. (round the final value to two decimal places.)

The length that a hanging spring stretches varies directly with the weight placed at the end of the spring. If a weight of 11lb stretches a certain spring 7in., how far will the spring stretch if the weight is increased to 44lb?

Astronomers suspect that a galaxy's type can be affected both by the conditions in the protogalactic cloud from which it forms ("initial conditions") and by later interactions with other galaxies.

If an object is in equilibrium,
