Apply: Click Reset. Set m to 1.0 kg, L to 2.0 m, g to 9.8 m/s2, and θ to –40 degrees. What is the maximum velocity of this pendulum? Show your work. (Hint: The exact height of the pendulum is now 0.468 m.)

Explanation:

m = Mass of pendulum = 1 kg

L = Length of pendulum = 2 m

g = Acceleration due to gravity =

h = Height of the pendulum = 0.468 m

= Angle of deflection =

The energy balance of the pendulum is as follows

The maximum velocity of this pendulum is .

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
