Aliquid at 30°c is poured very slowly into a calorimeter that is at temperature of 110°c. the boiling temperature of the liquid is 80°c. it is found that the first igm of the liquid completely evaporates. after pouring another 80 gm of the liquid the equilibrium temperature is found to be 50°c. the ratio of the latent heat of the liquid to its specific heat will be "c. (neglect the heat exchange with surroundingl

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.

cant without the picture! ?
