Answer:
The electric field inside the wire will remain the same or constant, while the drift velocity will by a factor of four.
Explanation:
Electron mobility, μ = 
where
= Drift velocity
E = Electric field
Given that the electric field strength = 1.48 V/m,
Therefore since the electric potential depends on the length of the wire and the attached potential difference, then when the electron mobility is increased 4 times the Electric field E will be the same but the drift velocity will increase four times. That is
4·μ = 
The modifications that are implemented after Tacoma bridge disaster are added trusses and openings below road decks to decrease oscillations.
<h3>Why Tacoma Bridge disaster occurred?</h3>
While marching, the natural frequency of the vibrations of marching soldiers matched up with the resonant frequency of the bridge. This resulted in the collapsing of the bridge in seconds.
Because of the disaster of the Tacoma Narrows Bridge, the bridge was strengthened by adding trusses as well as openings below road decks so as to decrease vibrations caused by running vehicles on the bridge.
Thus, the modifications that are implemented after Tacoma bridge disaster are added trusses and openings below road decks to decrease oscillations

Explanation:
Here is a link to a video to tell you about this.
Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass.
