A760 n man stands in the middle of a frozen pond of radius 6.0 m. he is unable to get to the other side because of a lack of friction between his shoes and the ice. to overcome this difficulty, he throws his 1.2 kg physics textbook horizontally toward the north shore, at a speed of 6.0 m/s. how long does it take him to reach the south shore?

An ionic compound can conduct electricity when a it is dissolved in water b its crystals are ground into powder c it is in solid form d it is heated to just below its melting point

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

What is the major limitation to the light microscope?
