Answer:
6.746 ft/s^2
Explanation:
v(t)=50
v(0)=27
t=5/3600 = 1/720 hours
v(t)-v(0)= a(t-0)
50-27= a(1/720)
a= 23*720= 16560 mi/h^2
16560mi/h^2 * 5280/3600^2 (ft/s^2) =6.746 ft/s^2
Answer:
A group of protons and neutrons that are surrounded by electrons I think that's the answer...
Explanation:
We know
Pa=Patm+dgh+dgl
here Pa is pressure in pipe with higher level of liquid
Patm is atmospheric pressure
d is density
g is gravitational constant
h is height of lower liquid
l is difference is height of higher liquid
So Pb= Patm+dgh
here Pb is pressure lower level pipe
so
Pdiff=Pb-Pa
Pdiff=-dgl
We know
Density of kerosene is the reciprocal of it’s specific volume
so d=1/v=1/0.00122=820kg/m3
as g=9.81 and l=12cm
Pdiff= - 820*9.81*12/100
Pdiff = -965.304 Pa
Negative sign shows pressure decreases as the kerosene flows from point A
to point B as the pipe diameter decreases.
