Bio medical Science vs. Forensic Psychology?
when i was younger i always wanted to become a doctor, but now it seems unrealistic considering all the studying i have to do, time taken & the cost. so I've considered pursuing a degree in forensic psychology or bio medical sciences as i was always interested in researching, science & the medical field. anybody in those fields, what are the available job opportunities for a girl?

in recognition?

2 AnswersPhysics7 years agoMagnetic Field Q?
Consider a conducting ring of mass 2kg & radius 0.5m. It is placed vertical on a smooth horizontal surface. A magnetic field of flux density 10T is along the plane. The angular acceleration of the ring at the instance at which a current of 4A begins to flow, (the moment of inertia of the ring about its axis is 1/2mr^2) is?
