Acombination lock has a 1.1-cm-diameter knob that is part of the dial you turn to unlock the lock. to turn that knob, you grip it between your thumb and forefinger with a force of 0.66 n as you twist your wrist. suppose the coefficient of static friction between the knob and your fingers is only 0.13 because some oil accidentally got onto the knob. what is the most torque that you can exert on the knob without having it slip between your fingers?

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
