Answer:
GPS Satellites.
Explanation:
You will always be able to have access to 4 of them no matter where you are on the Earth. This is useful for triangulation.
Thomson experiment he calculated the charge to mass ratio just be passing the fundamental charge through a tube
He calculated the charge to mass ratio just by finding the deflection of charge while it is passing through the constant electric field
so here we will use the deflection as following
let say it passes the field of length "L"
so here we have

now in the same time if it deflect by some distance


now by solving this equation we can find e/m ratio
so here correct answer will be
the electron's charge-to-mass ratio
Answer:
a.Systems development life cycle
Explanation:
Of all the options the correct answer is a.Systems development life cycle.
Systems development life cycle: The life cycle phases of systems development include preparation, system assessment, system design, advancement, application, inclusion and testing, as well as maintenance and support.
So, we can see that the Systems development life cycle enables staff to systematically go through every step in the development process and has a lower probability of missing important user requirements.
The metal conducts the heat, which makes cooking easier.
A.) 3,800
* Add 1800+2000 because they are both going forward, and you are look for the total amount of forward force. Hope this helped good luck!!!
