Answer:
C) The pressure reading stays the same.
Explanation:
An electric conductor is an element with free electrons in its outer orbit
Answer:
v = 66.4 m/s
Explanation:
As we know that plane is moving initially at speed of

now we have




now in Y direction we can use kinematics



since there is no acceleration in x direction so here in x direction velocity remains the same
so we will have



The relationship between resistance R and resistivity

is

where L is the length of the wire and A its cross section.
The radius of the wire is half the diameter:

and the cross section is

From the first equation, we can then find the length of the wire when

(copper resistivity:

)
