<span>With a power supply able to produce 125 an of current, then the time on how long must the nails stay in the electrolysis chamber to receive 1.33×107 c of charge is 10 hours, then a minute of 29, and lastly, 20 more seconds. </span>
Answer:
Explanation:
a Downward acceleration of car A along the slope
= g sinθ - μ g cosθ
= g ( sinθ - μ cosθ)
= 9.8 ( sin 12 - .6 x cos 12 )
= 9.8 x ( .2079 - .5869 )
= - 3.714 m / s²
So there will be deceleration
v² = u² - 2 a s
= 18² - 2 x 3.714 x 24
= 324 - 178
= 146
v = 12 .08 m /s
b )
In the second case , kinetic friction changes
downward acceleration
= g ( sinθ - μ cosθ)
= 9.8 ( sin12 - .1 x cos 12 )
9.8 ( .2079 - .0978 )
= 1.079 m /s
there will be reduced acceleration
v² = u² - 2 a s
= 18² +2 x1.079 x 24
= 324 + 52
= 376
v = 19.4 m /s
Because it’s warmer and more humid
