When food is stored in a container (a can or a jar), the food and the container are heated to a very high temperature in order to kill the germs. then the lid is attached. when the food and the container cools, the air pressure under the lid drops below atmospheric pressure, and the lid is pushed down by the weight of the air above it. this is why lids "pop up" when you open a sealed container. suppose that a container of spaghetti sauce has a circular lid with a radius of 7.5 cm and that the air pressure underneath the lid is 42 kpa. how much force (in n) is required to lift the lid at sea level where the earth's atmospheric pressure is 101.325 kpa.

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.

you can cut your hand off if your not

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
