An open steel can of volume 216 L is filled to the top with gasoline at
13.5°C. When it warms to
36.0°C, how much gas spills
over? (Don't forget, both the can
and the gasoline are expanding.)
B = 36•10-6 C-1
a = 12•10-6 0-1
Iron or Steel
Gasoline
B = 950•10-6C-1
(Unit = L)

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

c) a core temperature of only ten thousand kelvin
