Aparticle of massmand chargeqenters a region of uniform magneticfieldb=b0ˆz. the field region extends fromx= 0 tox=l, and is effectively infinitein theydirection. the particle is initially traveling along thexaxis. after the particleleaves the magnetic field region, it is observed to have been bent by an angleθ < π2towardthe−yaxis.
a.) is the particle’s charge positive or negative?
b.) what was the particle’s initial momentum?

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.

explanation:

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
