I believe the answer is manipulation of information. Hope I helped!
Basically its just an air like fluid with chemicals.... just like air it just goes as it pleases and fills space
Answer:
time of collision is
t = 0.395 s

so they will collide at height of 5.63 m from ground
Explanation:
initial speed of the ball when it is dropped down is

similarly initial speed of the object which is projected by spring is given as

now relative velocity of object with respect to ball

now since we know that both are moving under gravity so their relative acceleration is ZERO and the relative distance between them is 6.4 m



Now the height attained by the object in the same time is given as



so they will collide at height of 5.63 m from ground
Right. You are true. The direction of the electric field is defined to be
the direction of the force on a small positive charge placed in the field.
That would be the dump truck. Momentum depends on how heavy a certain object is in motion. The more weight it has the harder it is to stop.
