    When preparing electrolyte for a lead-acid battery, it is important to pour the acid into water rather than the other way around. This is because pouring water into acid can cause a violent reaction, resulting in the acid splashing out and causing harm to the person handling it. On the other hand, pouring acid into water allows for better control of the reaction and minimizes the risk of splashing or accidents.

    Rotor is Permanent Magnet in 

    • BLDC

    • PMDC

    • BDC

    Correct Answer
    A. BLDC
    Explanation
    In a BLDC (Brushless DC) motor, the rotor is a permanent magnet. Unlike PMDC (Permanent Magnet DC) and BDC (Brushed DC) motors, which have a rotor with windings or brushes, a BLDC motor uses a permanent magnet rotor. This type of rotor design allows for more efficient and reliable operation, as there are no brushes to wear out or windings to maintain. The permanent magnet rotor also provides better control and speed regulation, making BLDC motors ideal for applications that require precise and variable speed control.

    • Force 

    • Velocity

    • Jerak

    Correct Answer
    A. Jerk 
    Explanation
    Jerk is the quantity we get if we take the derivative of acceleration in the time domain. Jerk is a measure of the rate at which acceleration changes over time. It describes how quickly an object's acceleration is changing, indicating the object's responsiveness to external forces. This concept is important in physics and engineering, particularly in the study of motion and the design of vehicles and machinery.
