Answer:
if you can provide the figure it would be quite easy for the people giving answers
Pressure<span> is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. We calculate the pressure applied to the system above by the expression:
P = F / A
where F = mg
P = mg / A
P = (7.5 x 9.8) / 0.6
P = 122.5 Pa</span>
Answer: 6.534 x 10^(-1)
Step-by-step explanation:
Six thousand five hundred and thirty four ten thousandth
6534/10000
Convert to decimal
6534/10000=0.6534
Then convert to standard form
0.6534=6.534 x 10^(-1)
Define the distance through the equation
![x=16t^2](https://tex.z-dn.net/?f=x%3D16t%5E2)
The distance against the time is given by
![\Delta x = 32 t \Delta t](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%2032%20t%20%5CDelta%20t)
![\Delta t = \frac{2}{10}s](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%20%5Cfrac%7B2%7D%7B10%7Ds)
When t=2s,
![\Delta x = 32(2)\frac{2}{10}](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%2032%282%29%5Cfrac%7B2%7D%7B10%7D)
![\Delta x = 12.8](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%2012.8)
There is a error in 12.8feet.
b) When t=5sec
![\Delta x= 32t\Delta t](https://tex.z-dn.net/?f=%5CDelta%20x%3D%2032t%5CDelta%20t)
![\Delta x= 32(5)*\frac{2}{10}](https://tex.z-dn.net/?f=%5CDelta%20x%3D%2032%285%29%2A%5Cfrac%7B2%7D%7B10%7D)
![\Delta x = 32](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%2032)
There is a error in 32 feet.
1 1/2 or 3/4
either or should work
