Afemale bear leaves her bear cubs in their den to go out in search of food. she travels one mile in 30 minutes, heading east. she travels quickly at first, but then she becomes tired and begins moving more slowly. she finds no food, so she then heads north for another 10 minutes. she finds a river so she is able to catch a few fish for her bear cubs. she then turns around and heads back toward her den. she travels southwest and returns home to feed her cubs. question: identify and describe all points of acceleration in the scenario about the bear and her cubs. make sure to explain why each example is a point of acceleration.

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.

Abeam of electrons moves at right angles to a magnetic field of 4.5 × 10-2 tesla. if the electrons have a velocity of 6.5 × 106 meters/second, what is the force acting on the electrons? the value of q = -1.6 × 10-19 coulombs.
