Answer:
It takes 
to accelerate the object from rest to the speed v.
Explanation:
From Newton's second law:
(1)
and the definition of acceleration,
(2)
we can solve this problem. Putting (2) in (1) we have:
and solving for 
and considering the initial time as zero (
) and the initial velocity also zero (
) we have:
Now, for a mass 
and the 
we can wrtie the same equation:
and substituting 
and 
:
So now, it only takes half the time to accelerate the object from rest to the speed v
The relation between volume and temperature is direct, this is the higher the temperature the higher larger the volume.
Therefore, if you want that your gas occupies a larger volumen, you should increase the temperature, assuming other conditions (pressure and number of moles) remain unchanged.
The new temperature may be calculated using the proportion:
V1 / T1 = V2 / T2
=> T2 = V2 * T1 / V1
T1 and T2 are in absolute degrees, so T1 = - 73 + 273.15 = 200.15 K
=> T2 = 360 ml * 200.15 K / 210 ml = 343
Answer: the temperature should be increased to 343 K
That is a lunar eclipse. At night, when the Earth is between the Sun and the moon, the moon would appear to be red. Just for future reference, a solar eclipse is when the Moon is between the Sun and Earth. Speaking of which, check out the solar eclipse this August!
