Aperson opens a 2- liter bottle of cola at a picnic. if the cap is left off the bottle, the cola will become 'flat' or lose its carbonation. which statement below best summarizes why the cap must be kept tightly in place if the cola is to remain fresh?

D.The cap keeps the pressure of the gas in the bottle at a high level preventing carbon dioxide from leaving the solution.

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
