Analyzing the Relationship between Mass and KE
Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a
100 kg ball traveling at 5 m/s.
A 1,000 kg ball traveling at 5 m/s would have
v kinetic energy
A 10 kg ball traveling at 5 m/s would have
kinetic energy
A 100 kg person falling at 5 m/s would have
v kinetic energy

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?

Which part of earth’s surface receives the most direct rays from the sun? a) equator b) ocean c) poles d) mountains

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes.which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature.sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent
