<h3>
Answer: 104.5 cubic cm</h3>
=======================================================
Work Shown:
r = radius = 1.045 cm
h = height = 30.48 cm
pi = 3.141 approximately
V = volume of cylinder
V = pi*r^2*h
V = 3.141*(1.045)^2*30.48
V = 104.547940002
V = 104.5 cubic cm
Answer:vapour gets stuckes into the carburetor when the car engine heat up with continuous acceleration and deceleration.
Explanation:Vapor lock occurs when the car engine gets heat up with continuous acceleration and deceleration. The automobile engine has to work harder during the hot summer days. An automobile engine runs hotter than usual in the stop-go traffic.. This extreme heat vaporizes the fuel in carburetor and fuel pump.
The most possible cause of 35% increase in time measured is due to the acceleration due to gravity which is 70% less than 9.80 m/s² at this location.
Explanation:
We know that for a linear motion
S=ut+(1/2)*a*t²
Where S= Distance covered
u= initial velocity
t=time period
a= acceleration due to gravity
Since the body is falling vertically downwards "a" is to be replaced by "g"
Moreover, The body is falling from rest "u"=0
Hence the equation reduces to S=1/2*g*t²
t²=2S/g
Since the "g" is in denominator thus a decreased value of "g" would mean increased period. Thus an increase of 35% in the period would translate to a 70% decrease in "g".
Work needed: 720 J
Explanation:
The work needed to stretch a spring is equal to the elastic potential energy stored in the spring when it is stretched, which is given by
where
k is the spring constant
x is the stretching of the spring from the equilibrium position
In this problem, we have
E = 90 J (work done to stretch the spring)
x = 0.2 m (stretching)
Therefore, the spring constant is
Now we can find what is the work done to stretch the spring by an additional 0.4 m, that means to a total displacement of
x = 0.2 + 0.4 = 0.6 m
Substituting,
Therefore, the additional work needed is
