A chemist mixes 300 grams of water at 75 degrees Celsius with 100 grams of water at 15 degrees Celsius. To find the final temperature of the water after mixing, use the equation m1(t1-t)=m2(t-t2), where m1 is the quantity of water at the hotter temperature, t1 is the temperature of the hotter water, m2 is the quantity of water at the cooler temperature, t2 is the cooler temperature of the cooler water, and t is the final temperature of water after mixing.

Hi,

My Mate told me this a few days back and was wondering if it were true.

Could someone tell me why,

the best answer gets 10 points, it should say why, and maybe give an example of another substance that does funny things like that.

a) the force on the wagon is as strong as the force on the horse. The horse is joined to the Earth by flat hoofs, while the wagon is free to roll on its wheels.



b) The forse pulls before the wagon has time to react so they move forward.



c) The forse pulls forward slightly harder than the wagonpulls backward on the horse, so they move forward.



i thought this question was pretty weird. answer "a" makes sense in the first sentence, but the socond sentence of choice a screws the answer up. choice b does not make any sense. and i'm not sure bout choice c. Does this question make sense?
