Answer:
A remote controlled (<em>or externally piloted) </em>sequence valve
Explanation:
First of all, a sequence valve is a pressure-operated valve that opens at an adjustable set pressure.
Sequence valves can be internally piloted or externally piloted.
- Internally piloted sequence valves are known as direct-acting sequence valve. This means that the pressure change they sense is from their main inlet valve.
- Externally piloted sequence valves have a pilot line in which the pilot signal to open the valve is from a source other than the line feeding it.
External pilot-operated sequence valves can be used to open and allow flow when a remote operation reaches a certain predetermined pressure.

<h3>What is a lens?</h3>
An optical device known as a lens uses refraction to focus or disperse a light beam. A compound lens is made up of multiple simple lenses (elements), typically aligned along a common axis, as opposed to a simple lens, which is one solid piece of transparent material. Glass or plastic are used to make lenses, which are then polished or molded into the required shape. In contrast to a prism, which just refracts light without focusing it, a lens can focus light to create an image. In addition to focusing visible light, lenses can also be used to disperse various types of waves and radiation, such as explosive, microwave, electron, and acoustic waves.

Answer:
You have to calculate
Explanation:
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.
Answer:
We obtain the average velocity instead of the instantaneus velocity.
Explanation:
The problem with calculating speed in this way is that an average speed is being calculated and not an instantaneous speed at a given point.
To calculate the instantaneous speed, a very small space interval must be measured at a given time.
