URGENTTT PLEASE HELPPPP. You put m1 = 1 kg of ice cooled to -20C into mass m2 = 1 kg of water at 2C. Both are in a thermally insulated chamber. For water L = 3.33 x 105 J/kg. The specific heat of ice is 2090 J/(kgC) and of water 4186 J/(kgC). How much does the ice heat up in order to bring the water down to 0C?A. 0.04CB. 0.4CC. 4CD. 10CE. 20C

You're sitting on a warm granite rock, enjoying the sunshine. You decide it's time to test the water. You take off your shoes and walk across the cool sand to the water. You wade into the water, enough to cover your feet. Brrr! The water is cold. You will have to wear a dry suit when you go diving.a. Which item - the granite rock, the sand, or the water - has the highest specific heat? Which has the lowest specific heat? b. Which item requires the least energy to increase its temperature? Explain your answer in terms of this item's specific heat.c. If the granite rock on which you were sitting has a specific heat of 600 J/(kgC), how much energy must be added to a 2-kilogram piece of it to increase its temperature from 20C to 30C? Show your work, including the equation you need to perform this calculation.d. What is the second law of thermodynamics? Use this law to describe why your feet got cold, not hot, when you put them in the water.

The diagram represents two small, charged, identical metal spheres, A and B, that are separated by a distance of 2.0 meters. If the two spheres were touched together and then separated, the charge on sphere A would be *q1= -1.6x10^-6Cq2=+1.0x10^-6 Cd=2mFinal answer is -3.0x10^-7 C, but I don't know why it is like that.
