1. Which of the following will create a MAGNETIC FIELD? Choose all thatapply.
1 A neutron moving in a circle whiletraveling at a constant speed of 20 in/min. A proton thatis slowing down from 500 km/h to 400 km/h. An electronmoving at a constant velocity of 60 mph due north.A neutrino that is speeding up from 1000m/s to 1200 m/s. An ion that is stationary.

b. Which of the following statements are IMPOSSIBLE? Choose all that apply.1 1 1 A moving ion created a magneticfield. A neutrino that was stationary emittedan EM wave. A neutron and a positive ion will repeleach other. A source and observer were movingtowards each other. As a direct result, there was not a DopplerEffect. A convex lens created a virtualimage. In milk, loud sounds travel the samespeed as soft sounds.

c. Which of the following statements are IMPOSSIBLE? Choose all that apply. 1 A perfectly functioning hydraulic had apressure of 33 psi in the fluid near the small piston and apressure of 19 psi in the fluid near the big piston.A 32 L container displaced 44 L oforange juice when fully submerged. A substanceunderwent melting during which its temperature changed 74°F. A 37 lb brick was fully submerged inwater. The buoyant force on the brick was 41 lb. As a directresult, the brick was neutrally buoyant. Last Sunday,the Sun heated the Moon via convection. Thetemperature inside a vacuum chamber was measured to be 13°C.
