"A decorative stone fell off the fence. Considering the presence of air, how does the kinetic energy (K) of the stone just before striking the ground compare to its potential energy (U) on the fence? a. K is equal to U. b. K is greater than U. c. K is less than U. d. It is impossible to tell." Answer: b. Kinetic Energy is greater than Potential Energy. Just before the decorative stone hits the ground, it will have a greater kinetic energy than its potential energy. Review: Before anything else, we need to understand the concepts of kinetic energy and potential energy. Kinetic energy is the work that an object needs to have in order for it to be in action or to accelerate. Basically, kinetic energy is the object's energy triggered by its motion in three dimensional space. The energy is collected through its acceleration and secures its magnitude until a change of speed happens. The kinetic energy of an object will be set to zero once it is put into rest; ...
Number discs of 2573 Answer: just draw circles then, inside each circle, write the numbers 1,1,1,10,10,10,10,10,10,10,100,100,100,100,100,1000,1000 Step-by-step explanation: since 3 is in ones place, so there are three 1s tens place is 7, so there are seven 10s hundreds place is 5, so there are five 100s thousands place is 2, so there are two 1000s. So, you will draw a total of 17 circles or disks
