1. Complete the following table showing the relationship between mass and weight. Object Mass (kg) Weight (N) Melon 1 kg Apple 0.98 N Pat Eatladee 25 kg Fred 980 N 2. Different masses are hung on a spring scale calibrated in Newtons. a) The force exerted by gravity on 1 kg = 9.8 N. b) The force exerted by gravity on 5 kg = N. c) The force exerted by gravity on kg = 98 N. d) The force exerted by gravity on 70 kg = N. 3. Does a person diet to lose mass or to lose weight? Explain.

v 154.9= 0.9 length length s little over 154.9cm

its a 5.5 n

glad that

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
