A student is investigating heat transfer. The student places the ends of a curved copper bar into two insulated cups, as
shown below. The copper bar is at 20°C, Cup 1 contains
40°C water and cup 2 contains 20°C water. Each cup
contains the same amount of water.
Part A Describe the direction of heat flow between the cups of water in the first few
minutes of the investigation.
Show your work:

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
