Show that atmosphere exerts pressure.

Physics

Explanation:

Put in some little water in a can and boil it until all the water evaporates. While being careful, cover the can with its lid so that it is airtight. Pour very cold water on the can and you'll observe the can crumbles inwards. This is due to atmospheric pressure which is higher on the outside of the can than inside.

Another observation is during siphoning.  Put one end of a pipe inside a tank with water and suck out the air in the pipe on the other end (Remember the end you suck on must be at a lower level than the water level in the tank – this creates a potential difference). You notice that when sucking out all the air in the pipe and the water starts exiting the end, it continues to draw water from the tank with no more sucking. This is also due to atmospheric pressure applying to the water in the tank.

inna [77]

Answer:

-48 N

Explanation:

mass of door (m) = 4 kg

acceleration of the door = 12 m/s^{2}

force exerted by the person = 48 N

From Newton's third law of motion, action and reaction are equal but opposite. Therefore the force exerted on the door by the person which is 48 N will be the same as the force exerted on the person by the door but opposite in its direction, and this would be - 48 N

Explain Why a flying aeroplane has more Kinetic Energy than a flying insect?
Airida [17]

Answer:

Why do insects fly so high?

Because the angle of attack is so high, a lot of momentum is transferred downward into the flow. These two features create a large amount of lift force as well as some additional drag. The important feature, however, is the lift.

Why an Aeroplane flying has kinetic  

A flying aeroplane has potential energy has it flies above the ground level. And since the aeroplane is flying motion is associated with it and thus possesses kinetic energy. Hence a flying aeroplane has both potential and kinetic energ
