Answer:
Explanation:
Given
For first case
launch angle 
at highest point 


For second case

at highest Point velocity is 

as there is no acceleration in x direction therefore horizontal velocity is same
Organisms, organs, tissues, cell ....
a more specific answer would be:
organism, organ system, organ, tissue, cell, atom
Because it is if you know you know and it is also helping the sentwcnde and air and confiscation
Answer:
Approximately
(rounded down,) assuming that
.
The number of repetitions would increase if efficiency increases.
Explanation:
Ensure that all quantities involved are in standard units:
Energy from the cookie (should be in joules,
):
.
Height of the weight (should be in meters,
):
.
Energy required to lift the weight by
without acceleration:
.
At an efficiency of
, the actual amount of energy required to raise this weight to that height would be:
.
Divide
by
to find the number of times this weight could be lifted up within that energy budget:
.
Increasing the efficiency (the denominator) would reduce the amount of energy input required to achieve the same amount of useful work. Thus, the same energy budget would allow this weight to be lifted up for more times.
