A rectangular container of base 50 cm by 30cm is filled with water to a deapth of 5cm. how much is the pressure exerted at the base? (Take pw=1000kg/me and g=10m/s2)

Six pendulums of mass mand length las shown are released from rest at the same angle theta from vertical. rank the pendulums according to the numberof complete cycles of motion each pendulum goes through perminute. a. l= 1m m=2kg b. l= 4m m=1 kg c. l= 2 m m= 2 kg d. l= 1 m m= 4 kg e. l= 2 m m = 4 kg f. l= 4m m = 4kg
