V0 and gains a speed v0. If it were accelerated instead through a potential difference of 2V0, what speed would it gain? Potential: A proton is accelerated from rest through a potential difference and gains a speed . If it were accelerated instead through a potential difference of , what speed would it gain? v02–√ 8v0 4v0 2v0

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
