C) alternating current .

Not if both speeds are in the same units.
However, if the 254 is 'centimeters per time' and the 100 is 'inches per time',
then the speeds are equal.
<h2> The potential and kinetic energy of airplane are affected by these factors </h2>
Explanation:
When airplane rises up , it requires potential energy . This potential energy can be taken from the kinetic energy of airplane .
Thus if the speed of wind is larger , it can either oppose the motion of velocity or can favour the velocity of airplane . By which its kinetic energy is effected .
If the weight of airplane is changed , it will effect the potential energy required . Thus heavier plane requires higher potential energy for attaining the same height .
Thus these two factor has important role in the flight of airplane .
Ok, let me see if I can help
Sound is caused by vibrations. These can pass through a solid, liquid, and gas. But not through vacuum because there are no particles
