Answer: 0.4911 kg
Explanation:
We have the following data:
is the density of gasoline at
is the average coefficient of volume expansion
We need to find the extra kilograms of gasoline.
So, firstly we need to transform the volume of gasoline from gallons to :
(1)
Knowing density is given by: , we can find the mass
of 8.50 gallons:
(2)
Now, we have to calculate the factor by which the volume of gasoline is increased with the temperature, which is given by:
(3)
Where is the initial temperature and
is the final temperature.
(4)
(5)
With this, we can calculate the density of gasoline at :
(6)
Now we can calculate the mass of gasoline at this temperature:
(7)
(8)
(9)
And finally calculate the mass difference :
(10)
(11) This is the extra mass of gasoline
Answer:
The value is
Explanation:
From the question we are told that
The mass of the car is
The period of the circular motion is
The radius is
Generally the frequency of the circular motion is
=>
=>
