Answer:
(a) 41.75m/s
(b) 4.26s
Explanation:
Let:
Distance, D = 89m
Gravity, 
= 9.8 m/
Initial Velocity, 
= 0m/s
Final Velocity, 
= ?
Time Taken, 
= ?
With the distance formula, which is
D = 
+ 
and by substituting what we already know, we have:
89 = 
×9.8×
With the equation above, we can solve for :
Now that we have solved , we can use the following velocity formula to solve for :
, where 
is also equals to , so we have
By substituting 
, 
, and 
,
We have:
Answer:
False
Explanation:
The Concentration of Acid or Base is the ph of the solution.
In any case, your mass would be<em> 68 kg </em>no matter what
The study of sound is called sonics and the study of sound waves are acoustics
The gravity on Neptune is 11.15 m/s²
the gravity on earth is 9.81 m/s²
divide the Neptune and earth gravity we get 1.13
which means object on neptune is 1.13 heavier than earth
yield, weigh of the object on neptune is 1.13×15=17.04kg
