Some life forms move so slowly that their movement cannot be detected by normal observation. the best way to determine any movement is by placing a mark at some point, and observing any change in position from it. why is this true? a. the life form returns to that mark. b. the mark is a reference point. c. the mark is a standard unit. d. the mark makes measuring convenient.

Describe uniform velocity and variable velocity in short

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
