In a 1.25-t magnetic field directed vertically upward, a particle having a charge of magnitude 8.50 mc and initially moving northward at 4.75 km> s is deflected toward the east. (a) what is the sign of the charge of this particle? make a sketch to illustrate how you found your answer. (b) find the magnetic force on the particle.

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

Which is a substance that can be separated by physical means and is not the same throughout

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.
