Sully uses a battery and a coil of wire to create an electromagnet. using the same materials, if he wants to increase the strength of his electromagnet, he must  blank  the number of loops in the coil of wire along its length. if he uses an additional battery, the strength of his electromagnet will  blank. first blank( decrease, increase, not change)    second blank(decrease, increase, remain the same)

If forces acting on an object are unbalanced. true or false

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.
