The purpose of this lab is to determine whether the surface of an area would affect the coefficient of Friction. My classmates and I have learned a lot in this lab and that there could have been some errors in our lab because the strength of how a person pulls it might be a slight different than the normal force. I learned from this lab that the <span>surface area would have no effect on the coefficient of friction. </span>
States of matter can change through temperature
For example
Cold: Ice
Medium: Water
Hot: Steam
Pressure can change the temperatures at which the matter changes state
1) KE=1/2*m*v^2
1/2*45*40^2
KE=36,000J
2) PE=mgh
45*9.81*30
PE=13243.5J
Answer:
How hot or cold you feel depends on the rate at which your body is losing heat to the environment
Water on your skin acts pretty much like sweat. Water is more thermally conductive than air; therefore, the skin loses its heat to it much faster than it would to air.
Also, because water evaporates, it carries heat away from the skin and this increases the rate at which the skin loses its heat. The faster heat loss from the skin to water is what makes us feel cold when we are wet. But of course, the temperature of water has to be lower than the skin for this to occur, which is usually the case.
Answer:
i think the answer is D. surveys that ask people questions about specific topics, issues, or individuals
plz mark me as brainliest if this helped :)
