Answer:
B = 8.0487mT
Explanation:
To solve the exercise it is necessary to take into account the considerations of the Magnetic Force described by Faraday,
The magnetic force is given by the formula

Where,
B = Magnetic Field
I = Current
L = Length
Angle between the magnetic field and the velocity, for this case are perpendicular, then is 90 degrees
According to our data we have that
I = 16.4A
F = 0.132N/m
As we know our equation must be modificated to Force per length unit, that is

Replacing the values we have that

Solving for B,


Answer: A: the electrons move so fast that their mass cannot be measured
Explanation: because they are so fast scientist and other people cannot measure them
Answer:
The power required to move each bale is 30 lbf.ft/sec.
Explanation:
F= 40lbf * sin (30º)
F=20lbf
P= F*v
P=20 lbf * 1.5 ft/sec
P= 30 lbf.ft/sec
Answer:
Explanation:
Yesterday before i texted you it was like 11:00 and me and my friends were at the park and we were talking and there were like three boys and they came u to us and they said guess are size and i was like shoe size ? and they were like n ah you know what what i mean i just said i d k like how would i know and than my friend told them i was a v irgin and the may be like 30 min after they kept talking i just said im tired so i was going home and they invited them to there houses boys are like so weird in LA
