Se tiene un círculo metálico de radio 1cm y B = 2,02x10-4 /°C . ¿En cuántos °C se debe elevar la temperatura , de tal modo que el nuevo radio del círculo sea igual a 1.02 cm ?​​

Membrane vesicles containing an internal sodium chloride (nacl) concentration of 0.14 m are placed into separate beakers each containing a different solution. the first beaker contains 0.14 m sucrose, while the second beaker contains 0.14 m calcium chloride (cacl2). the temperature is 25°c. what is the solute potential inside the vesicles, expressed in units of mpa?
