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.
The direction of current flow is given by an arrow in the electrical circuit.
Several categories are used to categorise electrical circuits. One-way current only flows through a direct-current circuit. As with most residential circuits, an alternating-current circuit is a channel for transmitting electrical current that pulses back and forth numerous times each second.
A battery or generator, a device that provides energy to the charged particles that make up the current, a device that uses current, such as a lamp, an electric motor, or a computer, and the connecting wires or transmission lines make up an electrical circuit.
A source of electrical power, two wires that can transmit current, and a light bulb make up an electrical circuit. Both wires have one end connected to a cell terminal and the other end connected to a light bulb. When the light bulb is turned off, the electrical circuit is disrupted.

The atoms/ particles that are in the gas have gotten energy from the heat, because of that, they zoom around the container, putting pressure on it :) hope it helps :)
The mass of a school bus if it can accelerate from rest to 15.5 m/s over 8.25s with 7,500 N of force is 3989.4kg.
HOW TO CALCULATE MASS:
- The mass of an object can be calculated by dividing the force applied to the object by its acceleration.
- According to this question, a bus can accelerate from rest to 15.5 m/s over 8.25s. The acceleration can be calculated as follows:
- The mass of the bus = 7500N ÷ 1.88m/s²
- The mass of the bus = 3989.4kg
- Therefore, the mass of a school bus if it can accelerate from rest to 15.5 m/s over 8.25s with 7,500 N of force is 3989.4kg.
