You're lying on a towel, enjoying the sunshine. You decide to venture down to the water. Ouch, the sand is hot! You run to the water, where you cool your burning feet.

A. Why is the water cooler than the sand?

B. If the sand you ran across has a specific heat capacity of 835 J/(kg°C), how much energy must be added to a 2-kilogram pile of it to increase its temperature from 40°C to 50°C? Show your work.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
