Three liquids are at temperatures of 8°C, 20°C, and 30°C, respectively. Equal masses of
the first two liquids are mixed, and the equi-
librium temperature is 14°C. Equal masses of
the second and third are then mixed, and the
equilibrium temperature is 26.5°C.
Find the equilibrium temperature when
equal masses of the first and third are mixed.
Answer in units of C.

What is magnetic flux? explain faraday's law of induction.

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j
