Energy from the Sun travels to Earth as . a. mechanical energy a. mechanical energy b. chemical energy c. radiant energy d. combustion

The sun produces radiation which is what causes things such as severe sun burns (sun poisoning), or skin cancer

So i believe its Radiant Energy.

this could be newton#'s law of cooling. the cooling curve is exponential

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
