To calculate the deflection of a dial gauge with a least count of 0.01mm, you read the measurement indicated by the needle on the dial gauge after it has been set to the initial position. The deflection is the difference between the initial reading and the final reading on the dial gauge. Deflection = Final reading - Initial reading.
The Q wave is often negative because it reflects the depolarization of the interventricular septum from left to right in the heart, resulting in an initial negative deflection on the electrocardiogram. This is a normal finding in most individuals and is considered a part of the normal electrical activity of the heart.
Yes, the initial velocity can be negative in a physical system.
The most common abnormal heart rhythm preceding cardiac arrest is ventricular fibrillation. In this dysrhythmia, the ventricular walls contract randomly and rapidly, and do not effectively pump blood.
A defibrillator should typically deliver an initial energy of around 150-200 joules for ventricular fibrillation, and up to 360 joules for refractory ventricular fibrillation or pulseless ventricular tachycardia. The specific energy level will depend on the device and the patient's condition.

Negative, during the initial phase
Yes, displacement can have a negative value if an object moves in the opposite direction of its initial position.
Displacement is negative in a physical system when an object moves in the opposite direction of its initial position.
When the magnet is moved into the solenoid, the change in magnetic field induces an electric current in the solenoid. This induced current then creates a magnetic field that opposes the initial magnetic field created by the permanent magnet. This opposing magnetic field causes the galvanometer deflection to be reversed.
The S-T interval represents the initial slow phase of ventricular repolarization. It is the time between completion of the QRS complex and beginning of the T-wave
