First of all, we need to calculate the magnetic field generated by the wire at a distance r=3.90 cm=0.039 m, which is given by:
where I=8.60 A is the current. Substituting numbers in the equation, we find
And now we can calculate the force exerted on the electron, which is given by:
where 
is the charge of the electron and 
is its speed. Substituting data in the formula, we find
What kinds of bonds can happen between the elements of a compound?
<span>Covalent and Ionic</span>
Answer:
a quantitative observation because it includes numerical data
Answer:
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.
Explanation:
Answer:
T=Lnsin
Please check the attached
Explanation:
The torque can simply be calculated by multiplying the length of the rod by the perpendicular force n as shown in the attached figure.
Note that sin90=1
T=Lsin(nsin90)
T=Lsinxn
T=Lnsin
