Se estudia el intercambio de energía de un deportista de alto rendimiento que realiza una actividad física. Los datos obtenidos son los siguientes: Trabajo realizado: 94,81 kcal
Cantidad de calor: 247,8 kcal
Duración del ejercicio : 115,6min
a)Realice un esquema del sistema y el entorno especificando las cantidades de calor y trabajo intercambiadas
b) Calcular la potencia mecánica desarrollada por el atleta y expresarla en kcal/hora
c) Calcular la potencia térmica desarrollada por el atleta y expresarla en kcal/hora
d)Calcular la tasa metabólica de esta persona y expresarla en kcal/hora
e) Suponiendo que el calor sale del organismo principalmente mediante la evaporación del sudor ¿Cuánta agua deberá beber este atleta para reponer la que perdió por transpiración?

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
