For a DC power source for arc welding with characteristics \(3V + I = 240\), what voltage \(V\) yields maximum power?
The maximum frictional force which comes into play when a body just begins to slide over another surface is called
If the kinetic energy of the body with constant mass becomes four times the initial value, then the new momentum will be:
A body starting with initial velocity zero, moves in a straight line as per the law \( s = 5t^3 - 3t^2 - 5 \) (where \( s \) is distance in meters and \( t \) is time in seconds). The acceleration of the particle after 0.5 seconds will be:
