Answer:
a ) -10780 Pa
Explanation:
b ) Initially the pressure inside lungs and atmospheric pressure are equal . When the gauge pressure of the lungs becomes negative , its pressure becomes less than the atmospheric pressure . It creates a pressure difference between the pressure acting on the open surface of water and surface of water inside the pipe which is connected to the lungs. This difference pulls the water inside the pipe.
Pressure difference = gauze pressure of lungs = h d g = 1.1 x 1000 x 9.8
= 10780 Pa.
Ray B. isn't possible for a converging lens, because after passing through focus ot would go parallel to the principal axis,
So, Correct option is :
=》Option B.)
Answer:
16,579.6
Explanation:
i think you multiply 362×45.8= 16,579.6 and then whatever your unit of measurement is
Then, it would continue the motion in direction of resultant force...
