Answer:
![\theta = 22.29](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2022.29)
Explanation:
Taking summation of force at perpendicular to the plane
![\sum F_p = 0](https://tex.z-dn.net/?f=%5Csum%20F_p%20%3D%200)
![2N_A +2N_B -mgcos\theta = 0](https://tex.z-dn.net/?f=2N_A%20%2B2N_B%20-mgcos%5Ctheta%20%3D%200)
![N_A +N_B - mgcos\theta = 0](https://tex.z-dn.net/?f=N_A%20%2BN_B%20-%20mgcos%5Ctheta%20%3D%200%3C%2Fp%3E%3Cp%3E)
![N_A +N_B = mgcos\theta](https://tex.z-dn.net/?f=N_A%20%2BN_B%20%3D%20mgcos%5Ctheta)
Taking summation along the plane, therefore we have
![\sum Fa = 0](https://tex.z-dn.net/?f=%5Csum%20Fa%20%3D%200)
![\mu N_A+\mu N_B - mgsin\theta = 0](https://tex.z-dn.net/?f=%5Cmu%20N_A%2B%5Cmu%20N_B%20-%20mgsin%5Ctheta%20%3D%200)
from equation 1 and 2 we have
![\mu =\frac{sin\theta}{cos\theta}](https://tex.z-dn.net/?f=%5Cmu%20%3D%5Cfrac%7Bsin%5Ctheta%7D%7Bcos%5Ctheta%7D)
![\mu = 0.41](https://tex.z-dn.net/?f=%5Cmu%20%3D%200.41)
![\mu = tan\theta](https://tex.z-dn.net/?f=%5Cmu%20%3D%20tan%5Ctheta%3C%2Fp%3E%3Cp%3E)
![\theta = tan^{-}\mu](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%5E%7B-%7D%5Cmu)
![\theta = 22.29](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2022.29)
A barometer measures atmospheric pressure.

This would be a funny game.
Inertia, according to first Law of Newton, means that when you throw a ball it will continue moving unless a force acts over it.
Without inertia, the ball instead of continue moving, would stop as soon as it leaves your hand or foot. You had to stay pasted to the ball unitl it reaches the desired destiny for it continue moving.
Solution :
A) Electric current is the flow of electrons .
B) We know, by ohm's law :
V = I × R
Putting given values in above equation, we get :
V = 0.56 × 72 V
V = 40.32 V
Hence, this is the required solution.
