Hot water of mass 10 kg at 90°C is cooled for taking bath by mixing 20 kg of water at 20 °C, what is the final temperature of the water? (Specific heat capacity of water is 420J/kg )

b.

explanation:

10.0

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
