Answer:
Eje x
fr- F = m a
eje y
N-W =0
Explanation:
Para este ejercicio, debemos usar la segunda ley de Newton, donde se necesita fija un sistema de referencia el mas usado es un sistema horizontal y vertical para los ejes x e y
en el adjunto puede ver el diagrama de cuerpo libre correcto,
las fuerza son
Eje x
fr- F = m a
eje y
N-W =0
la ecuacion para la fuerza de roce es
fr = my N
Answer:(69,69,69)
Explanation:
The ratio of the intercortex of the inner circle has an area of 98:89. This is due to the fact the vector of the circle is no less than the ratio times the pie squared. Then pie squared the circumference will end up approximately at 68.83957 where you then round up to all 69's.
Answer:
14.9 v
Explanation:
V = IR
The voltages across the resistors will be proprtional to the values of the resistors
45 * 235 / (235 + 475) =
When light passes from rarer medium to denser medium, its speed decreases. Hence, light is refracted when it passes from air to water.
