The motion of an object thrown in outer space best demonstrate an object will .

A) continue moving in a straight line at a constant speed forever unless acted on by an unbalanced force.

B) continue moving in a straight line at a constant speed regardless of being acted on by an unbalanced force.

C) continue moving along a straight or curved path it had just before released, forever unless acted on by an unbalanced force

spectral lines lyman is one set

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

this would be about 43%

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
