What is positive edge triggered D flip flop? An edge-triggered flip-flop changes states either at the positive edge (rising edge) or at the negative edge (falling edge) of the clock pulse on the control input. The three basic types are introduced here: S-R, J-K and D. Click on one the following types of flip-flop. What […]
How many steps are in a stride?
What is the first thing a technician should do before performing diagnosis on any electrical circuit?
What is the first thing a technician should do before performing diagnosis on any electrical circuit? Perform starter circuit voltage drop tests; determine needed repairs. Disable the ignition and fuel system before performing these tests. Check the voltage drop between each component in the starter circuit while operating the starter motor. Voltage drop between each […]
Which is the power stroke in 4-stroke engine?
Which is the power stroke in 4-stroke engine? Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. What happens in each stroke of a 4-stroke engine? An internal-combustion engine goes through four […]
What is the expression for net force net force?
What is the expression for net force net force? When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, FNet = […]
What is the difference between socialism and a pure command economy?
What is the difference between socialism and a pure command economy? explain the difference between socialism and a pure command economy. In socialism, the government owned some, but not all, factors of production. In a pure command economy, the government owns all factors of production. Which type of economic system is most likely to experience […]
What is the difference between friction and antifriction bearings?
What is the difference between friction and antifriction bearings? Friction bearings commonly use lubricating oil to separate the moving component from the mated non-moving bearing surface. An antifriction bearing is a bearing that contains moving elements to provide a low friction support surface for rotating or sliding surfaces. Why are ball and roller bearings called […]
What is redundancy work?
What is redundancy work? Redundancy occurs when employers reduce their workforce because a position is no longer required. “Redundancies are a form of dismissal, and can happen when an employee’s job no longer exists. This may be due to an employer needing to reduce their workforce, close the business, or certain work is no longer […]

How does regenerative braking make a car more energy efficient?
How does regenerative braking make a car more energy efficient? Regenerative braking uses an electric vehicle’s motor as a generator to convert much of the kinetic energy lost when decelerating back into stored energy in the vehicle’s battery. It takes the inefficiency of braking and simply makes the process less wasteful. How does regenerative braking […]
