Answer:
scalar quantity
Explanation:
Vector quantities have two characteristics, a magnitude and a direction. Scalar quantities have only a magnitude.
To solve this problem it is necessary to apply the concepts related to Faraday's law and the induced emf.
By definition the induced electromotive force is defined as


Where,
Electric field
B = Magnetic Field
A = Area
At the theory the magnetic field is defined as,

Where,
N = Number of loops
I = current
Permeability constant
We know also that the cross sectional area, is the area from a circle, and the length is equal to the perimeter then
A = \pi r^2
l = 2\pi r
Replacing at the previous equation we have that

Where,
R = Radius of the solenoid
r = The distance from the axis
Re-arrange to find the current in function of time,

Replacing our values we have


If the object's velocity and acceleration have <em>opposite signs</em>, then the object is slowing down.
Answer:
6.46*10^-11m
Explanation:
We can use the equation of the center of the mass of two atoms

If we take the origin at the center of the molecule carbon monoxice, xc will be 0, so
=
=6.46*10^-11m
