Somewhere in outer space a star of mass m.
moving with velocity so headed toward a star
et mass 2 m at rest. The impact parameter in
this case is b. calculate the speeds and direction
of the two stars.

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced?

J. j. thomson’s experiment disproved the theory that an atom

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
