2 trains each traveling with a speed of 37.5km/h is aapproaching each other on the same straight track.a bird that can fly 60km/h flies off from one train when they are 90km and head directly from the other train .on approaching other train it flies back to the first and so on.total distance covered by bird is?

how many turns of solenoid is required to produce a magnetic field having magnitude of 3.0 T upon the application of 600A current if the solenoid is 8.50 m long and is having 4500 turns.  (note: \mu _(0)=4\pi x10^(-7)T. m/A).

Two objects with masses m1 and m2 are moving along the x-axis in the

positive direction with speeds v1 and v2, respectively, where v1 is less than

v2. The speed of the center of mass of this system of two bodies is

a) less than v1.

b) equal to v1.

c) equal to the average of v1 and v2.

d) greater than v1 and less than v2.

e) greater than v2.

how many turns of solenoid is required to produce a magnetic field having magnitude of 3.0 T upon application of 600A current if the solenoid is 8.50 m long and is having 4500 turns. ( \mu _(0)=4\pi x10^(-7)T. m/A).

what is the magnitude of a magnetic field produced by a 6.50 m long solenoid and is having 3500 turns if a 555A current is applied on it? (note:  \mu _(0)=4\pi x10^(-7)T. m/A).

determine the distance from a long straight wire that would produce a Magnetic Field three times that of the Earth's own field upon the application of 60.0 Ampere currents. (assuming that Earth's Magnetic Field is equal to 5x10^(-5)T and \mu _(0)=4\pi x10^(-7)T. m/A).

determine the Current in a long straight wire that would produce a magnetic field that produces a Magnetic Field four times that of Earth's Magnetic Field located at a distance 9.0 cm from the wire. (assuming that the Earth's Magnetic Field is equal to 5x10^(-5)T and \mu _(0)=4\pi x10^(-7)T. m/A).

Barium ion with a 2+ charge travels at a speed 800 m/s and is acted upon by a magnetic force having a magnitude of 1700.0 N. Determine the magnitude of magnetic field acting perpendicularly on Ba^(2+).

Barium ion with a 2+ charge travel at a speed 800 m/s is moving perpendicular to the magnetic field with a magnitude of 2.0 T. Determine the magnitude of magnetic force acting on Ba^(2+).
