A3.00 kg mud ball has a perfectly inelastic collision with a second mud ball that is initially at rest. the composite system moves with a speed equal to one- third the original speed of the 3.00 kg mud ball. what is the mass of the second mud ball?

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

The direction of the current in an alternating current circuit remains constant. is direct. changes repeatedly. changes randomly.

Bradley was working in the lab. he accidentally poured a container of concentrated hydrochloric acid into his container of distilled water. not thinking much of it, he continued with his work as if nothing happened. which of these would be the result of this laboratory accident? a) the water will change to a bright pink color. b) the new solution would decrease in temperature. c) the solution has now become a good conductor of electricity. d) hcl and water have the same chemical and physical properties, so nothing would happen.
