A (7.55 m by 7.55 m) square base pyramid with height of 3.52 m is placed in a uniform vertical electric field of 65.9 N/C. The pyramid encloses no charge. b 7.55 m 3.52 m 65.9 N/C Calculate the electric flux which goes out through one of the pyramid’s four slanted surfaces. Answer in units of N m2 /C.

The law of reflection states that the angle of reflection is equal to the angle of

Use the illustration to describe how the electromagnetic spectrum changes as its frequency moves from radio waves to higher energy gamma waves in terms of wavelength and amplitude.

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.
