Final speed of the airplane as it slows down, v = 230 m/s
It took the pilot 7 seconds to get down to its final speed. Let a is the acceleration of the plane. We know that the rate of change of velocity of an object is called its acceleration. The mathematical expression is given by :
The negative sign shows that the airplane is slowing down or deceleration. Hence, this is the required solution.
Direct current is used in any electronic device with a battery for a power source. It is also used to charge batteries, so rechargeable devices like laptops and cell phones
Combustion of Hydrogen involves combining oxygen and hydrogen essentially so when oxygen and hydrogen combine water is produced, following chemical equation describes this process.
