A science teacher ran a marathon. She showed her students the silver blanket she was given after the race to keep her warm. A group of students investigated how the colour of the blanket affected how much infrared radiation was absorbed.

Give one reason why the infrared lamp was placed the same distance from both cans.

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

find the sum of the two horizontal vectors and the sum of the two vertical vectors
