The north pole of one magnet attracts the south pole of another magnet. The needle of a compass is itself a magnet; the end of the needle that points north is capped with an arrow and often painted red. A typical compass with a red, arrow-capped needle pointing near due north. In light of this, explain why the arrow‑capped end of a compass needle is attracted to the North Pole of the Earth.

i guess it’s a and b

unbalanced force

explanation:

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
