Answer : The initial volume was, 71.2 mL
Explanation :
To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.
The equation follows:

where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
We are given:
![P_1=0.85atm\\V_1=?\\T_1=66^oC=[66+273]K=339K\\P_2=0.60atm\\V_2=94mL\\T_2=43^oC=[43+273]K=316K](https://tex.z-dn.net/?f=P_1%3D0.85atm%5C%5CV_1%3D%3F%5C%5CT_1%3D66%5EoC%3D%5B66%2B273%5DK%3D339K%5C%5CP_2%3D0.60atm%5C%5CV_2%3D94mL%5C%5CT_2%3D43%5EoC%3D%5B43%2B273%5DK%3D316K)
Now put all the given values in above equation, we get:


Therefore, the initial volume was, 71.2 mL
it has an electrons in a fixed path together on energy levels.
<h2>Answer : By weighing the costs and benefits of an environmental issue
</h2><h3>
Explanation :</h3>
The law makers usually conduct many studies before a law is imposed. They try to explore many other options available to the current environmental issue and then come to a conclusion to make a law.
They also weigh the cost aspect along with the benefit of the ongoing environmental issue. They try to come up with something which appears to be cost effective and result bearing.
Answer:
the pressure in the pipe in the case when there is no net force on the car is 81,726 N/m^2
Explanation:
a. The computation of the pressure in the pipe in the case when there is no net force on the car is shown below
As we know that
Pressure = F ÷ area
Also
F = mg
Now
= (1500 × 9.8) ÷π (0.24)^2
= 81,726 N/m^2
Hence, the pressure in the pipe in the case when there is no net force on the car is 81,726 N/m^2
