Consider the energy balance equation for a closed system: deltaU+deltaEk +deltaEp=Q-W. Given the scenarios and systems described below, sort the energy balance equation terms according to if they are less than zero, equal to zero, or greater than zero. Scenario 1: You put a jar of pickles, intially at room temperature, into the refirgerator, and the jar contents cool to 38*F. Consider the system to be the jar contents, and assume that the shelf in the refrigerator is at the same height as the counter which the jar initially rested. Scenario 2: The same pickle jar falls off the shelf and is about to hit the floor. Consider the pickle jar to be the system, and for there to be negible heat transfer and temperature change during this process. Scenario 3:On a cold day, water rests in a small crack in an asphalt road. As night falls, ice freezes, expands, and causes the crack to grow into a pothole. Consider the system to be water.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
