How is fraunhofer diffraction different from fresnel diffraction? A. Fraunhofer diffraction does not involve a point source of light
B. Fraunhofer diffraction involves no more than two wave sources
C. Fraunhofer diffraction involves parallel rays of light between the source, obstacle , and screen
D. Fraunhofer diffraction results in a continuous distribution of wavelets across an area

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

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
