Friction occurs when the surfaces and heat of two surfaces grind against each other.
I think these are the answers
(50 gal / 5 min) x (.0037854 m³/gal) x (1 min / 60 sec)
= (50 · 0.0037854 · 1) / (5 · 60) m³/sec
= 0.000631 m³/sec
Answer:
The effect of your walking will create a force on the airline acting downwards, due to the weight. By Newton's thirds law the airline will exert an equal and opposite reaction force directed downwards.
Explanation:
The weight of all the passengers acts downwards on the floor of the Airplane.
The Airplane exerts an equal and opposite force on the passengers, with the help of its propulsion due to which the flight keeps on flying without falling down.
Hence by changing the frame of reference we can observe the force which is responsible for the reaction.
Around 70-72% of earth’s surface is covered in water (most of it is salt water).
Hope this helps.
The atomic number of Na is 11
Thus it’s electronic configuration is 2,8,1
It’s valency is 1.
Thus it will loose an electron to form a stable compound with a completely filled outermost shell.
Na looses 1 electron
