    What is the best way to reduce radiation exposure in a hospital laboratory?

    1. Homework Statement a gamma raidiation source (226Ra) is used in hospital laboratory. if shielding is considered as a means of control how many centimeters are needed to reduce the radiation to 1% of what a worker would be exposed to without shielding? assume the shield material is a)...

    Coils rotating in a magnetic field find maximum emf and magnetic feild strength

    Homework Statement coils rotating in a magnetic field are often used to measure unknown magnetic fields. As an example, consider a coil of diameter 2.00 cm with 72.0 turns that is rotated about an axis perpendicular to the field at a rate of 20.0 Hz. If the maximum induced emf in the coil is...

    Magnetic repulsion between 2 wires?

    Homework Statement A wire with a weight per unit length of 0.040 N/m is suspended directly above a second wire. The top wire carries a current of 30.0 A and the bottom wire carries a current of 90.0 A. Find the distance of separation between the wires so that the top wire will be held in...

    Proton and magnetic field question to see if i got the answers right?

    hey i just need to know if these answers are right i think i got it hopefully A proton of mass 1.67 x 10-27 kg is fired with a velocity of 1000 ms-1, into a uniform magnetic field of 2.00 T where the velocity and magnetic field are at right angles. (a) What is the magnitude and...
