The navigation rules entail vessels restricted in their ability to maneuver to display appropriate flag or lights. During the day of engagement of vessel in diving activities the rigid replica of the international code flag "ALPHA" must be exhibit not less than 3.3 feet while during night time the vessel must display the navigation light which is red and white and this requirement does not affect divers red and white flag which may be required by state to mark a divers location. The "A" flag is a kind of navigational signal which indicates the vessel’s restricted maneuverability and do not pertain to diver.
The labeled points which is Letter B in the given Image is the point that the axis of rotation passes through. This problem is an example of rotational dynamics, formerly an object moves in a straight line then the motion is translational but when an object at inactivity lean towards to continue at inactivity and an object in rotation be possible to continue rotating with continuous angular velocity unless bound by a net external torque to act then is rotational. In a rotational motion, the entity is not treated as a constituent part but is treated in translational motion. It points out with the study of torque that outcomes angular accelerations of the object.
Answer:
3894531 coulombs
Explanation:
1 hour = 3600 seconds
Let g = 10m/s2
The distance that the car travel at 25 m/s over an hour is
s = 25 * 3600 = 90000 m
The total mechanical energy of the car is the sum of its kinetic energy to reach 25 m/s, its potential energy to climb up 200m high hill and it work to travel a distance of s = 90000m with F = 500 N force:
![\sum E = E_k + E_p + E_W](https://tex.z-dn.net/?f=%20%5Csum%20E%20%3D%20E_k%20%2B%20E_p%20%2B%20E_W)
![\sum E = mv^2/2 + mgh + Fs](https://tex.z-dn.net/?f=%5Csum%20E%20%3D%20mv%5E2%2F2%20%2B%20mgh%20%2B%20Fs)
![\sum E = 750*25^2/2 + 750*10*200 + 500*90000 = 46734375 J](https://tex.z-dn.net/?f=%5Csum%20E%20%3D%20750%2A25%5E2%2F2%20%2B%20750%2A10%2A200%20%2B%20500%2A90000%20%3D%2046734375%20J)
This energy is drawn from the battery over an hour (3600 seconds), so its power must be
![P = E / t = 46734375/3600 = 12982 W](https://tex.z-dn.net/?f=P%20%3D%20E%20%2F%20t%20%3D%2046734375%2F3600%20%3D%2012982%20W)
The system is 12V so its current is
or 1081.8 Coulombs/s
The the total charge it needs for 1 hour (3600 s) is
C = 1081.8 * 3600 = 3894531 coulombs
Answer:
Collisions may take place between <u>the reactants</u>.
Explanation:
The collision frequency must be greater than the frequency factor for the reaction. A collision between the reactants must occur.
