The correct option for the statement “As air flow up the side of a mountain, the air pressure”.

Answer to Problem 9RAT
The correct option for the statement “As air flow up the side of a mountain, the air pressure” is option (b).
Explanation of Solution
The weather forecasting depends on the pressure of air at that location, so the pressure is an essential factor that decides the weather of a particular region. If the barometric pressure is high in an area, this will cause air to move to a region of lower pressure.
The pressure of air is the force exerted by the molecules per unit volume, as the height increasing the volume of the air decreases that ultimately decreases the pressure of the air, thus atmospheric pressure decreases as the altitude increases.
So, during mountain climbing, the blood from the nose comes out as the pressure of the air decreases and the pressure of the blood inside the body is no longer balanced by the atmospheric air.
Conclusion:
Therefore, the correct option for the statement “As air flow up the side of a mountain, the air pressure” is option (b).

Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why. Please fully explain why it's clockwise, Thank youarrow_forwardA planar double pendulum consists of two point masses \[m_1 = 1.00~\mathrm{kg}, \qquad m_2 = 1.00~\mathrm{kg}\]connected by massless, rigid rods of lengths \[L_1 = 1.00~\mathrm{m}, \qquad L_2 = 1.20~\mathrm{m}.\]The upper rod is hinged to a fixed pivot; gravity acts vertically downward with\[g = 9.81~\mathrm{m\,s^{-2}}.\]Define the generalized coordinates \(\theta_1,\theta_2\) as the angles each rod makes with thedownward vertical (positive anticlockwise, measured in radians unless stated otherwise).At \(t=0\) the system is released from rest with \[\theta_1(0)=120^{\circ}, \qquad\theta_2(0)=-10^{\circ}, \qquad\dot{\theta}_1(0)=\dot{\theta}_2(0)=0 .\]Using the exact nonlinear equations of motion (no small-angle or planar-pendulumapproximations) and assuming the rods never stretch or slip, determine the angle\(\theta_2\) at the instant\[t = 10.0~\mathrm{s}.\]Give the result in degrees, in the interval \((-180^{\circ},180^{\circ}]\).arrow_forward
