Answer:
Time taken to travel remaining 228 miles = 2.4 hours.
Explanation:
Total distance = 876 miles.
Distance traveled after speed reduction = 228 miles
So, distance traveled before = 876 - 228 =648 miles.
Time taken for this = 6 hours.
Speed before speed reduction = 648/6 = 108 mph.
Speed after speed reduction = 108 - 13 = 95 mph
Time taken to travel remaining 228 miles = 228/95 = 2.4 hours.
1) d = V*t >>>as you double the av. speed the distance become doubled.
2) after you draw the victors you will find the total displacement = 1 meter to the left.
3) V =d/t =( 8km)/(1.25hr) = 6.4km/hr
To calculate for the pressure of the system, we need an equation that would relate the
number of moles (n), pressure (P), and temperature (T) with volume (V). There are a number of equations that would relate these values however most are very complex equations. For
simplification, we assume the gas is an ideal gas. So, we use PV = nRT.<span>
PV = nRT where R is the universal gas
constant
P = nRT / V</span>
<span>P = 3.40 mol ( 0.08205 L-atm / mol-K ) (251 + 273.15 K) / 1.75 L </span>
<span>P = 83.56 atm</span>
<span>
</span>
<span>Therefore, the pressure of the gas at the given conditions of volume and temperature would be 83.56.</span>
