In unit-vector notation, what is the torque about the origin on a jar of jalapeno peppers located at coordinates (3.0 m, -2.0 m, 4.0 m) due to force  F→1 = (9.7 N) î - (4.8 N) ĵ + (5.3 N) k̂ ((a), (b) and (c) for  î ,  ĵ and  k̂ components respectively), force  F→2 = (-9.7 N) î - (4.8 N) ĵ - (5.3 N) k̂ ((d), (e) and (f) for  î ,  ĵ and  k̂ components respectively), and the vector sum of  F→1 and  F→2 ((g), (h) and (i) for  î ,  ĵ and  k̂ components respectively)? Repeat previous part for the torque about the point with coordinates (3.0 m, 2.0 m, 4.0 m) ((j), (k) and (l) for  î ,  ĵ and  k̂ components respectively).

Find the torque about the point (1, −2, 1) due to the force F = 2i − j + 3k acting at the point (1, 1, −3).

Force F = (5.58 N)î – (6.71 N )k acts on a pebble with position vector 7 = (2.79 m ) – (7.59 m ) k, relative to the origin. - What is the resulting torque acting on the pebble about (a) the origin and (b) a point with coordinates (3.43 m, 0, -3.30 m)? (a) Number i i k Units (b) Number i i i k Units

Your answer is partially correct. Review Conceptual Example 2 before attempting this problem. The moon has a diameter of 3.48 x 106 m and is a distance of 3.85 x 108 m from the earth. The sun has a diameter of 1.39 x 10⁹ m and is 1.50 x 10¹1 m from the earth. Determine (in radians) the angles subtended by (a) the moon and (b) the sun, as measured by a person standing on the earth. (c) Determine the ratio of the apparent circular area of the moon to the apparent circular area of the sun. These calculations determine whether a total eclipse of the sun is really "total." (a) Number 0.00904 (b) Number i 0.0093 (c) Number i 0.945 Units rad Units Units rad No units
