Hello There!
Let's first talk about <em>"What Is Friction"</em>
<u>Friction is a force that pulls when two object touch each-other. Friction happens because the molecules on one surface interlock with the molecules on another surface.</u>
<u></u>
Now, let's get back to our original question "What Effect Does Friction Have On A Roller Coaster"
On a roller coaster, friction is a force that opposes motion and significantly slows the cars as they move on the track.
Answer:
The maximum temperature is 90.06° C
Explanation:
Given that
t= 0.1 mm
Heat generation
Heat transfer coefficient
Here one side(left side) of the wall is insulated so the all heat will goes in to right side .
The maximum temperature will at the left side.
Lets take maximum temperature is T
Total heat flux ,q
So the total thermal resistance per unit area
R=0.002 K/W
We know that
q=ΔT/R
30=(T-90)/0.002
T=90.06° C
The maximum temperature is 90.06° C
The author mentions that Shine made several mistakes in her experiment. Describe one major mistake that Shine made.
When a motorboat passes by, a disturbance or vibration in the lake water is created which travels in all the directions. A water wave is a combination of longitudinal wave as well as transverse wave. If you are a particle of water in the lake, then you would be hit by nearby water particle which would set you in motion. you would travel up and down forming crest and trough and sideways. The energy would be transported forward, as you would collide with other particle and the wave moves forward. your position would not change. only the energy would be transported.
