when 1.00g of sucrose C12H22O11 was combusted in a calorimeter to give CO1 and H20, the temperature rose from 25.00 to 27.32 C. The calorimeter itself had a heat capacity of 837JC and was submersed in 1500.0g of water. Find the heat of combustion of sucrose. How would I go abo...
The value of y changes by 3 units when x changes by 0.1 unit. About how fast is y changing?
vector A has a magnitude of 57 m and points in a direction 20 degrees below the positive x axis. vector B has magnitude of 70 m and points in a direction 57 degrees above the positive x axis. Find the magnitude of the vector D = A-B.

The Andrews Corporation produced satellite dishes, was purchased by another compay, which was a cable company: The Total Cost function for the New Company is: TC = 1,000 + 16Q 16Q2, where the demand curve for Satellite Dishes is PS = 400 QS and that for the cable...
What are proper techniques to induce crystallization from a saturated solution? (Select all correct answers.) Allowing the solution to cool down. Scratching the outside of the container with a glass rod. Seeding the solution. Adding a solvent that lowers the solubility of the...
Consider the electric field created by a very long charged line of negative linear charge density -2.50 nC/m. A small positive point charge of 7 mC moves from a distance of 9 cm to a distance of 17 cm. How much work is done by the electric field?
I think I got part A and B. I need help on part C. How do I do it?
A hollow cylindrical resistor with inner radius r1 and outer radius r2, and length l, is made of a material whose resistivity is rho. A.Find the resistance for current that flows radially outward. Divide the resistor into concentric cylindrical shells and integrate. Express yo...
