Answer: Option (b) is the correct answer.
Explanation:
According to ohm's law, the relationship between voltage, resistance, and current is that current passing through a conductor is directly proportional to the voltage over resistance.
Mathematically, I =
From this relationship we can see that when we decrease the voltage, and do not change the resistance, the current will also decrease. As current is directly proportional to voltage and inversely proportional to resistance.
Answer:
Force = 533.33N
Explanation:
Given the following data;
Power = 40000watt
Velocity = 75m/s
To find the force;
Making force the subject of formula, we have;
Force = 533.33N
