He pump in a water tower lifts water with a density of rhow = 1.00 kg/liter from a filtered pool at the bottom of the tower up hT = 32 m to the top of the tower. The water begins at rest in the pool and comes to rest at the top of the tower. The pump is 100% efficient in lifting the water, and it lifts a volume of Vw = 5.2 liters of water up the tower every second. The water tower sits on a hill that is Te = 25 m above sea level. Let gravitational potential energy be zero at ground level. Calculate the power. Pp in Watts, of the pump

What is the final velocity of the initial velocity of 25 and -50?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
