Please help due to today For science! 1. Does the bowling ball have more potential energy or kinetic energy as it sits on top of the building? Why?


2. Does the bowling ball have more potential energy or kinetic energy as it is halfway through its fall? Why?


3. Does the bowling ball have more potential energy or kinetic energy just before it hits the ground? Why?


4. What is the potential energy of the bowling ball as it sits on top of the building?


5. What is the potential energy of the ball as it is halfway through the fall, 20 meters high?


6. What is the kinetic energy of the ball as it is halfway through the fall?


7. What is the kinetic energy of the ball just before it hits the ground?


In both equations, m stands for mass and needs to be measured in kilograms (kg). The speed is shown by v and is measured in meters per second, The height of his hand is measured in meters (m). Lastly, the gravitational constant is g, and it has a value of.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
