Answer:</h3>
189.07 kPa
<h3>
Explanation:</h3>
Concept tested: Boyle's law
<u>We are given;</u>
- Initial volume of the syringe, V1 is 16 cm³
- Initial pressure of the syringe, P1 is 1.03 atm
- New volume of the syringe, V2 is 8.83 cm³
We are required to calculate the new pressure of the syringe;
- We are going to use the concept on Boyle's law of gases.
- According to the Boyle's law, for a fixed mass of a gas, the pressure is inversely proportional to its volume at constant temperature.
- At varying pressure and volume, k(constant) = PV and P1V1=P2V2
Therefore, to get the new pressure, P2, we rearrange the formula;
P2 = P1V1 ÷ V2
= ( 16 cm³ × 1.03 atm) ÷ 8.83 cm³
= 1.866 atm.
- Thus, the new pressure is 1.866 atm
- But, we need to convert pressure to Kpa
- Conversion factor is 101.325 kPa/atm
Thus;
Pressure = 1.866 atm × 101.325 kPa/atm
= 189.07 kPa
Hence, the new pressure of the air in the syringe is 189.07 kPa

Awnser: 600 meters per hour
Step by step explication:
Covert 14 minutes to a fraction of an hour by dividing it by 60, because 60 is how many minutes in an hour and we need to convert it to a decimals. Then divide the distance, 150 meters by the fraction of an hour, .25 to abstain the velocity (speed) of 600 meters per hour.
Answer: Heat engines convert chemical energy to mechanical energy
Explanation:
Answer:
a) 3.6 sec
b) 17.7 m/s
c) 17.7 m/s
d) 63.6 m
Explanation:
y = (25sin45)t - 4.9t^2 =17.7t - 4.9t^2
a) to find hang time set y = 0
4.9t^2 = 17.7t or t = 3.6 sec
b) vx = 25cos45 = 17.7 m/s
c) vy = 25sin45 = 17.7 m/s
d) To find the range R, use the results in (a) and (b) into the equation R = vxt:
R = (17.7 m/s)(3.6 sec) = 63.6 m
