Answer:
Ohm's Law
Explanation:
The relationship: 
where V represents the voltage across a resistor of resistance "R" through which a current (I) flows,
is known as Ohm's Law in honor of Georg Ohm, who discover this proportionality.
The distance covered is 1000 m
Explanation:
The rocket is moving by uniformly accelerated motion, so we can find the distance it covers by using the following suvat equation:

where
s is the distance covered
v is the final velocity
t is the time
a is the acceleration
For the rocket in this problem, we have:
v = 445 m/s is the final velocity
is the acceleration
t = 4.50 s is the time
Substituting, we find the distance covered:

The answer would be 0.21 i believe if you use something we called F/Ma in grade school
Power (P) in "watts" in a circuit is the product in multiplying the current (I) in "amperes" and voltage (V) in "volts".
P = I x V ; I = P / V
Substituting the given values,
I = (25 W) / (230 V) = 0.1087 amperes
Therefore, the current is approximately 0.1087 A.
