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.
Answer:
the ratio of the kinetic energy of an electron to that of a proton if their wavelengths are equal is 1835.16 .
Explanation:
We know, wavelength is expressed in terms of Kinetic Energy by :
Therefore , 
It is given that both electron and proton have same wavelength.
Therefore,
.... equation 1.
.... equation 2.
Now, dividing equation 1 by 2 .
We get ,
Putting value of mass of electron = 
and mass of proton = 
We get :
Hence , this is the required solution.
It would be kinetic energy. Let's say the book is weighs 10 Newtons you need to use a force of 10 Newtons to lift the book. In other words it's positive. As you move the book you're giving it energy. Namely potential energy which will turn to kinetic energy if you let it go. So you're changing it's position and energy.
