A10.0 cm long wire is pulled along a u-shaped conducting rail in a perpendicular magnetic field. the total resistance of the wire and rail is 0.330 ohms . pulling the wire at a steady speed of 4.00 m/s causes 4.40 w of power to be dissipated in the circuit. a) how big is the pulling force? b) what is the strength of the magnetic field?

Answer

given,

length of wire = 10 cm = 0.1 m

resistance of the wire =  0.330 ohms

speed of pulling = 4 m/s

Power = 4.40 W

a) Force of pull = ?

b) using formula

  where B is the magnetic field

   v is the pulling velocity

   R is the resistance of the wire

      B = 3.01 T

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
