Professor belanovsky a.s. input control work on the residual knowledge of the school program in physics 1. the speed of the cochlea is 15 mm / min. the speed of the bee is 18 km / h. how many times is the speed of a bee greater than the speed of a snail? 2. the thickness of the razor blade is 0.05 microns, and its length is 4 cm. what pressure does the razor create if a force of 200 m1n is applied to it? 3. calculate the kinetic energy of a sparrow weighing 50 g if it flies at a speed of 36 km / h. 4. the density of the red blood cell is 1.1 g / cm. express it in μg / μm.​
