Answer:
Option C
Explanation:
given,
velocity of airplane = 80 m/s
angle with the horizontal = 15°
speed of the ground= ?
when the plane is taking off the horizontal component of the velocity is v cosθ
so,
ground speed of the airplane is = 
= 
v = 77.27 m/s
horizontal velocity of the air plane comes out to be 77.27 m/s ≅ 77 m/s
so, the correct option is Option C
The ball at the top of the ramp has potential energy but when it rolls down or when it is rolling down it has kinetic. The ball has kinetic energy when it is moving or rolling down the ramp but there is Potential energy when the ball is at the top or is sitting at the bottom still. when the ball is rolling down the ramp it has heat energy because of how it get speed and it starts to heat up.
<span>The statement, The word atom
comes from a Greek word that means “able to duplicate”, is false. The greek
word for atom is atomos. The a- in atom means “not” and –tom means “cut”. So it
is not ot cut or it cannot be cut. It is common definition is indivisibility. This
definition is defined by the philosopher Democritus. He observed that as he cut
the sugar cube into smaller fraction, it reduces to nothing that cannot be seen
in the eye. And so he proposed that definition.</span>
