Answer:
100 m/s
Explanation:
We'll begin by converting 1 km to m. This can be obtained as follow:
1 km = 1000 m
Finally, we shall determine the final velocity of the car. This can be obtained as follow:
Initial velocity (u) = 0 m/s
Acceleration (a) = 5.0 m/s²
Distance (s) = 1000 m
Final velocity (v) =?
v² = u² + 2as
v² = 0² + (2 × 5 × 1000)
v² = 0 + 10000
v² = 10000
Take the square root of both side
v = √10000
v = 100 m/s
Therefore, the speed value of the car is 100 m/s.
I think it's Quadratic. With all the rapid increase of the values of y.
Answer: The gauge pressure of the air in the tires is 179.5 kPa.
Solution :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = Atmospheric pressure + gauge pressure = 101 kPa + 165 kPa = 266 kPa
= final pressure of gas = ?
= initial volume of gas =
= final volume of gas =
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get the final pressure of gas.
Gauge pressure = Absolute pressure - atmospheric pressure = (280.5 - 101) kPa= 179.5 kPa
Therefore, the gauge pressure of the air in the tires is 179.5 kPa.
