(a) Ajet airplane flying from Darwin, Australia, has an air speed of 260 m/s in a direction 5.0" south of west. It is in the jetstream, which is blowing at 35.0 m/s in a direction 15° south of east What is the velocity of the airplane relative to theEarth? (b) Discuss whether your answers are consistent with your expectations for the effect of the wind on the plane’spath.

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

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
