Answer: 0.516 ft/s
Explanation:
Given
Length of ladder L=20 ft
The speed at which the ladder moving away is v=2 ft/s
after 1 sec, the ladder is 5 ft away from the wall
So, the other end of the ladder is at
Also, at any instant t
differentiate w.r.t.
The throttle is the name of the device that regulates the amount of fuel going into the engine of a personal watercraft (PWC). The throttle make the PWCs maneuverable. TO MAINTAIN STEERAGE, YOU MUST APPLY THROTTLE!<span> They are built for quick, sharp turns, low-radius circling, and rapid acceleration</span>
For every O ion, two Na ions are needed to balance charges. Which ratio represents the relationship between Na and O?
2 Na:1 O
The answer is a. generator!
We apply the following equation
T = 2π * sqrt (L/g)
Where g is the gravity = 9.8 m/s^2
L is the longitude of the pendulum (Height of the tower)
T is the period. (T = 18s)
We find L.............> (T /2π)^2 = L/g
L = g*(T /2π)^2...........> L = 80.428 meters
