Un esquiador parte del reposo desde la parte superior en A de una pendiente de 20 m de altura y desliza sobre ella 60 m hasta B y luego se desplaza una cierta distancia ‘d’ sobre la superficie horizontal hasta detenerse en C. El coeficiente de fricción en toda la superficie es de 0,25. Determinar: a) La velocidad al final de la pendiente en B
b) La distancia ‘d’ entre B y C
c) La velocidad en C en caso de no existir la fricción en su recorrido

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

part 1: describe the mass and the surface temperature of dwarf stars.

part 2: explain using complete sentences where on the hr diagram you would expect to find a dwarf star based on its physical properties.

part 1: the mass of a dwarf star is very small and the surface temperature of dwarf stars are high and they have the lowest absolute brightness.

part 2: on the hr diagram you would expect to find a dwarf star based on its physical properties at an absolute brightness of -2 to -4

hope this
