Amass of gas under constant pressure occupies a volume of 0.5 m3 at a temperature of 20°c. using the formula for cubic expansion, what will be the volume at a temperature of 45°c without a change in pressure?

In what direction does the medium move relative to the direction of the wave? explain.

As the distance from a magnet increases, what happens to the magnet force?

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.
