Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a string & are in static equilibrium. the 30 kg red sphere has more charge than the 8 kg green sphere. the total charge magnitude on the spheres is 1171 μc & they have the same polarity. as a result the tension is 5062.5 n & the centers of the spheres are 0.78 m apart. determine the charge magnitude on each sphere.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

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
