d. Systematic
Explanation:
Types of sampling:
The selection of sample is arbitrary and each member has an equal chance of selection.
This selection does not take probability of selection into account rather focuses on the convenience and proximity of the member for selection.
An ordered system is decided to choose the members for this sample.
This sampling plan divided the population into groups, called clusters. A cluster is then randomly selected from the selected population.
The members of the population are divided into groups, called strata. A random sample is drawn from each strata.
Answer:
A pneumatic system is a system that uses compressed air to transmit and control energy. Pneumatic systems are used extensively in various industries. Most pneumatic systems rely on a constant supply of compressed air to make them work. This is provided by an air compressor.
A hydraulic system is a drive technology where a fluid is used to move the energy from e.g. an electric motor to an actuator, such as a hydraulic cylinder. The fluid is theoretically uncompressible and the fluid path can be flexible in the same way as an electric cable.
Explanation:
<h3>Examples of pneumatic systems and components
</h3><h3>Air brakes on buses and trucks.
</h3><h3>Air brakes on trains.
</h3><h3>Air compressors.
</h3><h3>Air engines for pneumatically powered vehicles.
</h3><h3>Barostat systems used in Neurogastroenterology and for researching electricity.
</h3><h3>Cable jetting, a way to install cables in ducts.
</h3><h3>Dental drill.</h3>
<h3>Hydraulic systems use the pump to push hydraulic fluid through the system to create fluid power. The fluid passes through the valves and flows to the cylinder where the hydraulic energy converts back into mechanical energy. The valves help to direct the flow of the liquid and relieve pressure when needed.</h3>
