A would be the best answer to this question
The force acting on the passenger is equal to:
![F=N-mg](https://tex.z-dn.net/?f=F%3DN-mg)
Where N is the normal force and mg is a force of gravity. If a person feels like their weight is increased by 60% at the bottom that means normal force is 60% stronger than the force of gravity:
![N-mg=0.6mg](https://tex.z-dn.net/?f=N-mg%3D0.6mg)
We know that net force must be equal to the centripetal force:
homo. It is a mixture because it has different things in it. If they are distributed homogeneously ...
Answer:
![P_2=222.22kPa](https://tex.z-dn.net/?f=P_2%3D222.22kPa)
Explanation: By using Gas Law, the new pressure can be calculated as follows:
Gas law states:
![(P_1V_1=P_2V_2)\Rightarrow(1)](https://tex.z-dn.net/?f=%28P_1V_1%3DP_2V_2%29%5CRightarrow%281%29)
Using (1), and Identifying the knowns and unknowns, and plugging in (1) we get the following results:
![\begin{gathered} V_1=10cm^3=1\cdot10^{-5}m^3 \\ P_1=100\text{kPa}=100000Pa \\ V_2=(0.45)\cdot V_1=(0.45)\cdot(1\cdot10^{-5}m^3)=4.5\cdot10^{-6}m^3 \\ V_2=4.5\cdot10^{-6}m^3 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20V_1%3D10cm%5E3%3D1%5Ccdot10%5E%7B-5%7Dm%5E3%20%5C%5C%20P_1%3D100%5Ctext%7BkPa%7D%3D100000Pa%20%5C%5C%20V_2%3D%280.45%29%5Ccdot%20V_1%3D%280.45%29%5Ccdot%281%5Ccdot10%5E%7B-5%7Dm%5E3%29%3D4.5%5Ccdot10%5E%7B-6%7Dm%5E3%20%5C%5C%20V_2%3D4.5%5Ccdot10%5E%7B-6%7Dm%5E3%20%5Cend%7Bgathered%7D)
Finally, the New pressure is calculated as follows:
<span>Kinetic energy is a body that possesses by
virtue of being in motion. While potential energy possesses a body by virtue of
its position relative to others, stresses within itself, electric charge, and
other factors. As the “car” moves along the track its kinetic energy coverts to
potential energy when it moves up or down one of the hills. With the initial motion
already pushing it when it reaches a slope or dip it uses its own motion to
move along the track. </span>
<span>For
my track I used cardboard and for my “car” I used a spool of thread. The weight
of the cardboard is about .13 kg and the spool is about 0.9</span>
<span>P.s. these were my answers and I got a pretty good grade, for the weight of the track and "car" I did estimate it.</span>
