Answer:
A force is a push or a pull. It causes an object at rest to move. It can cause an object that is moving to change speed, or the distance covered over time. It can also change which way the object is moving its direction. Lastly, it can also cause an object to stop moving completely. A force has both magnitude and direction. An object with balance forces or a net force of zero will not change position.

Answer: B.) Kinetic energy
Explanation:
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.
Answer:
D
Explanation:
Think about like charges meaning the charge is the same.
Which only D has two charges and are the same, positive will repel against positive charge so select D.
Answer:
The orbital speed can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth's radius plus the height above the earth - in this case, 6.59 x 106 m.
