ANSWER IS ON CHEGG BUT I DONT HAVE A SUBSCRIPTION 0.645 kg of molten silver at its melting point (962C) is added to 0.800 kg of water at 20.0 C. What is their final equilibrium temperature?
(Don't forget, silver LOSES heat when it solidifies.)

Ais the answer hope this

The upward force acting on the wing of a airplane in flight is known as the "lift" force. (d)

So are u adding some additional catalyst

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
