Answer:
The distance covered by the rocket after fuel ran out is 
Explanation:
Given that the rocket moves with an acceleration 
time 
Since the rocket starts from rest initial velocity 
The distance it travelled within this time is given by 
Velocity at this point is given by 
Given that at this height it runs out of fuel but travels further. Here final velocity 
(maximum height), initial velocity
and time to zero velocity 
Thus it travels 
more after fuel running out. The distance covered during this period is given
Answer:
A turbine and generator produce the electricity
Explanation:
"A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.
It increases with the motion of particles within a substance
I just took the test
Answer:
, downward
Explanation:
There is only one force acting on the ball during its motion: the force of gravity, which is given by
where
m is the mass of the ball
is the acceleration of gravity (downward)
According to Newton's second law,
where F is the net force on the object and a is its acceleration. Rearranging for a,
As we said, the only force acting on the ball is gravity, so F = mg and the acceleration of the ball is:
Therefore, the ball has a constant acceleration of downward for the entire motion.
Dependant variable is something which you MEASURE during an experiment
So your answer would be : B
