Answer:
8,809.024m
Explanation:
Displacement , y = (gt^2/2
)
g = 9.8 m/s^2
t = 42.4s
y = (9.8 (42.4*42.4)) / 2
y = 8,809.024m
The absence of external force in the outer space, allows the piece of rock to continue moving at the same velocity for thousands of years.
<h3>Absence of external force on the outer space</h3>
The outer space is almost an absolute vacuum, because it's nearly empty. There is no matter such as air in the outer space that will provide an external force needed to change the velocity of the piece of rock.
From Newton's first law of motion, an object in a state of rest or uniform motion in a straight line, will continue in that state unless it is acted upon by an external force.
Thus, the absence of external force in the outer space, allows the piece of rock to continue moving at the same velocity for thousands of years.

Answer:
the car will slow down due to the change in speed
Answer:
b. 
Explanation:
As we know that the electric field due to infinite line charge is given as
here we can find potential difference between two points using the relation
now we have
now we have
now plug in all values in it
now we know by energy conservation
answer
no
Explanation:
I do not think that I would because even though its a conductor in the insulator I think it would insulate it before it will work (not sure if that makes sense)
