Statement A: An aeroplane flying at an altitude possesses only K. E.St...
Statement A: An aeroplane flying at an altitude possesses only K.E.
Statement B: An aeroplane flying at an altitude possesses both K.E and P.E.
Explanation:
An aeroplane flying at an altitude possesses both kinetic energy (K.E) and potential energy (P.E). Therefore, Statement B is true.
Kinetic Energy (K.E):
Kinetic energy is the energy possessed by an object due to its motion. It depends on the mass and velocity of the object. When an aeroplane is flying at an altitude, it possesses kinetic energy due to its motion through the air. The faster the plane is flying, the greater its kinetic energy will be.
Potential Energy (P.E):
Potential energy is the energy possessed by an object due to its position or height in a gravitational field. When an aeroplane is flying at an altitude, it possesses potential energy due to its height above the ground. The higher the plane is flying, the greater its potential energy will be.
Explanation of the Statements:
- Statement A: This statement claims that an aeroplane flying at an altitude possesses only kinetic energy. This statement is incorrect because an aeroplane possesses both kinetic energy and potential energy when it is flying at an altitude. Therefore, statement A is false.
- Statement B: This statement correctly claims that an aeroplane flying at an altitude possesses both kinetic energy and potential energy. This statement is true because an aeroplane's motion through the air gives it kinetic energy, and its height above the ground gives it potential energy. Therefore, statement B is true.
Conclusion:
An aeroplane flying at an altitude possesses both kinetic energy and potential energy. Therefore, Statement B is true.
