Answer:
a. contractor
Explanation:
The contractor has to approve or give the sign for the drawings to be made, otherwise you can't do anything.
Answer:
U=0.198J
Explanation:
The potential energy associated with two point charges is given as
U=(Kq1q2)/r
Where k=8.99*10⁹N.m²/C²
r=0.5m,
q₁=2μc,
q₂=5.5μc
If we substitute values into the equation we arrive at
U=(8.99*10⁹N.m²/C²* 2*10⁻⁶*5.5*10⁻⁶)/0.5
U=197.78*10⁻³
U=0.198J
From the calculation above, we can conclude that the potential energy between the two system of charges is 0.198J
Answer:Mechanical Engineers
Explanation: Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches.
I think it is C because if have to send it to someone you would want them to be able to open it
