synchronous means it is based on a clock...it performs operations based on every clock tick....asynchronous operations execute irregardless of the clock signal

Synchronous flip-flops change outputs synchronously to a clock signal, while asynchronous flip-flops can change outputs regardless of the clock signal. Asynchronous flip-flops are not as commonly used due to potential timing hazards, while synchronous flip-flops are widely used in digital circuits to ensure reliable operation.
The types of digital counters include asynchronous (ripple) counters and synchronous counters. Asynchronous counters change state based on the clock input, with each flip-flop triggering the next. Synchronous counters have all flip-flops triggered simultaneously by a common clock signal.
Flip-flops are commonly used in VLSI physical design for sequential logic circuits due to their ability to store binary information and synchronize signals. They help in controlling the timing of signals and reduce the chances of metastability issues. Flip-flops also provide a way to control the state of a circuit at specific clock edges, aiding in sequential circuit design.
Wearing high-heels can restrict ankle movement and reduce jumping ability due to reduced stability and ankle range of motion. Tennis shoes provide good support and traction, which may improve jumping height compared to high-heels. Flip flops offer minimal support and can lead to lower jumping height due to reduced stability and grip on the ground.
A bag of rice, a block of butter, a liter of water, or a small laptop can weigh approximately one kilogram.
Some forces that act against gravity include air resistance, buoyancy (in liquids or gases), and electromagnetic forces (such as the force between two magnets pushing apart). These forces can counteract the downward pull of gravity in different situations.
