What are the signs of δs univ, δs surr, and δs sys, respectively, for water freezing at -10°c? a) δs univ is positive, δs surr is negative, and δs sys is positive. b) δs univ is negative, δs surr is negative, and δs sys is positive. c) δs univ is positive, δs surr is positive, and δs sys is negative. d) all three values are positive.

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

technology is the application of the knowledge gained by science.
