Which of the following statements about ohm's law is true? a. increasing the voltage decreases current. b. keeping the same voltage and decreasing resistance decreases the current. d. to increase the current, decrease the resistance.

The correct answer is option D

The Ohm's Law states that current passing through a conductor is directly proportional to the voltage across the conductor.

Current =voltage/ resistance

The resistance causes hindrance in the path of the current and does not allows it to flow so, we must reduce the resistance to increase the flow of current in the conducting wire.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
