There is an assassin who climbed to the top of the catwalk balcony of a mansion to get a good view of his target who is 3.1 ft tall. The assassin pulls the trigger when the target us 94 ft away, discharging the bullet at 63 degrees to the level of the victim's head. Find the height of from which
the assassin shot the victim.
O 184.5 ft
O 197.4ft
O 181.4 ft
O 187.6 ft

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

The electronic structure or chlorine is 2.8.7 what is the electronic structure of fluorine?

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
