In Earth’s current orbit, it is 1.52 × 1011 meters from the Sun at aphelion and 1.47 × 1011 meters at perihelion. Using these values and the equation given in part A, what is the eccentricity of Earth’s current orbit? Round your answer to three decimal places.

c. magnitude and direction

radiation

explanation:

heat is transmitted by radiation

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
