A 500 mL bottle at room temperature (25˚C) of water is poured over 120 g of ice that is (-8˚C). What will be the final temperature of the water be when all the ice has melted? You can ignore loss of heat to the room.
You are explaining to a friend why the crew of the International Space Station feels weightless while orbiting the Earth. Your friend responds that he thought gravity was just a lot weaker up there. Show that it isnt so by calculating the acceleration due to gravity 350 ...

I have a blank table to fill in.It says divide m by 3 m÷3
A woman that is 5'4" stands 15 ft from a streetlight and casts a four-foot long shadow. Determine the height of the streetlight and the degree measure of the angle of elevation form the tip of her shadow to the top of the streetlight, both accurate to two decimal places.
Hydrated copper sulfate is heated. Using the speculative chemical equation CuSO4*5H2O-->CuSo4+5H2O, show how you could have predicted, by calculations, what the final weights in the crucibles might be. Show calculations for two starting weights between 1 and 4 grams.
thank you! the answer was 96.3
Consider the vectors A = 2.00 i + 7.00 j and B = 3.00 i - 2.00 j. (a) Sketch the vector sum C = A + B and the vector subtraction D = A - B. (b) Find analytical solutions for C and D first in terms of unit vectors and then in terms of polar coordinates, with angles measured wit...
A block of iron at 39.0°C has mass 2.30 kg. If 3.50×104 J of heat are transferred to the block, what is its resulting temperature?
Triangle RSU has two of its points(R and S) on the sides of a circle. Line SU forms a secant ray that passes through the diameter of the circle. Angle S is 30 degrees, the measure of arc RS is 84 degrees, and RU is tangent to the circle at R. Find the measure of angle U. 27&de...
