Answer:
When the ejected air is moving in the downward direction then the thrust force acts in the upward direction, due to reversal thrust, the jets can take off vertically without needing a runway this way.
Explanation:
Newton’s third law motion states that for every action there will be an equal and opposite reaction.
Thrust reversal is also known as reverse thrust. It acts opposite to the motion of the aircraft by providing the deceleration.
Commercial aircraft moves the ejected air in the forward direction means that the thrust will acts opposite to the motion of the aircraft that is backward direction due to thrust reversal. This thrust force might be used to decelerate the craft.
Uses of thrust reversal in practice:
When the ejected air is moving forward direction then the thrust force moving backward direction due to reversal thrust the speed of the craft slows down.
When the ejected air is moving in the downward direction then the thrust force acts in the upward direction, due to reversal thrust, the jets can take off vertically without needing a runway this way.
Burning of paper is the answer
Answer:
Explanation:
Given that
Wavelength λ=192 nm
So energy of photon,E
Now by putting the values
We know that
Kinetic energy given as

battery
<span>power sector</span></span>
<span>Both
planets, Mars and the Earth are terrestrial planets. This means that their
surface is rocky, they have Mountains, canyons, valleys, ice caps..</span>
