a 5-meter ramp lifts objects to a height of 0.75 meters.What is the mechanical advantage of the ramp?
coldgirl [10]
This is an Engineering question, and the answer is reasonably simple. The mechanical advantage is given by:

MA = \frac{Distance 1}{Distance 2} on a lever or ramp system.

MA = \frac{5}{0.75}

MA = 6.67 (there are no units, as MA is a ratio)

What Celsius temperature, T2, is required to change the volume of the gas sample in Part A (T1 = 23 ∘C , V1= 1.69×103 L ) to a v
andrezito [222]

Answer:

319.15^{o}C[/tex]

Explanation:

When all other variables are constant, we are allowed to use the formula

\frac{T_{2} }{V_{2} } = \frac{T_{1} }{V_{1} } \\Which can be rewritten as T_{2} = \frac{T_{1} V_{2} }{V_{1} }if you make T2 the subject of the formula. This formula is true only if temperature is in Kelvin not degrees Celsius so T1 must be converted to KelvinNow to calculate T2[tex]T_{2}= \frac{296.15K*3.38.10^{3}L }{1.69.10^{3}L }= 592.3K = 319.15^{o}  C
