The volume of the vacuum chamber is 27.1 ∙ 103 m3. Before emptying the chamber, it is filled with air
with a density of 1.25 kg / m3. The pressure in the chamber is 101 kPa here. The temperature in the chamber is constant during pumping, and after
the pumping, there is only 0.70 kg of air left in
the chamber.

a) Calculate the temperature of the air in the chamber
and the pressure in the chamber after pumping.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
