Which method would you use to obtain the distance to each of the following?
an asteroid crossing earth’s orbit
a star astronomers believe to be no more than 50 light-years from the sun
a tight group of stars in the milky way galaxy that includes a significant number of variable stars
a star that is not variable but for which you can obtain a clearly defined spectrum

the answer to this is proletariats.

hope this : )

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
