The net change in velocity during the given time interval is equal to -0.665.
<u>Given the following data:</u>
- Initial time = 0.75 seconds.
- Final time = 2.25 seconds.
- Acceleration,
<h3>How to calculate the net change in velocity.</h3>
Since acceleration is the rate of change of velocity of an object, we would derive an expression for the velocity by differentiating with respect to time:
Substituting the time interval, we have:
V(t) = -0.665.

By the 1830s, farmers were using new fertilizers on crops and feeding artificial feeds to livestock. ... The Agricultural Revolution<span> was a period of technological improvement and increased crop productivity that occurred during the 18th and early 19th centuries in Europe</span>
Important changes in the Middle East between the 13th and 15th centuries include the 13 Century end of the First Crusade and the capture/founding of Jerusalem. After that came the rise of the Mongol/Turkish/Ottoman Empire during the 14th Century. The Ottoman transcontinental Empire controlled much of North Africa, Western Asia, and Southeast Europe. This led to the creation of important transcontinental trade routes and a boom of economic trade between the continents.
Pushing the Mongols north and fighting them, and the rebuilding of Beijing caused the Chinese decision to abandon major expeditions.
Answer:
0.027 cubic ft/min
Explanation:
Volume of water is V=V(t) Depth of water is h=h(t)
The relationship between V and h is
V=π/3.r2.h
Let
h0= the height of the cylinder = 24ft, r0= the radius of the opening = 10ft.
Since water level (h) rise with respect to flow rate we find an expression for r and substitute into V
r/h = r0/h0= 10/24 = 5/12
r = (5/12) h,
Substitute for r in V
so,
V=1/3.π.(h2)square = 1/3.π. 25/144.(h3)
When
h= 16ft
and dV/dt = 20ft3/min
,
dV/dt =1/3*π*25/144*h3*(dh/dt)
20ft3/min= 1/3*π* 25/144*h3*(dh/dt)
20 = 1/3*π*(16)3.(dh/dt)
Make dh/DT subject of formula
dh/dt=(20*3*144)/(25*π*4096) = 8640/321740.8
=
dh/dt= 0.027 ft3/min
