Un esquiador parte del reposo en lo alto de una colina que presenta una inclinación de 10.5 respecto a la horizontal. La ladera tiene 200m de largo y el coeficiente de fricción entre la nieve y los esquíes es de 0.0750. Al pie de la colina la nieve es horizontal y el coeficiente de fricción no cambia. ¿Qué distancia recorre el esquiador a lo largo de la parte horizontal de la nieve antes de detenerse?

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

An ideal gas is held in a container at constant volume. initially, its temperature is 5 degrees c and its pressure is 1.2 atm. what is its pressure when its temperature is 43 degrees c? answer in units of atm
