Answer:
b) Earth is passing Saturn in its orbit, with both planets on the same side of the Sun.
Explanation:
Retrograde motion is an optical effect due to the fact that Earth rotates more quickly than the planet that apparently has a retrograde motion in the sky.
For this particular case, Saturn has a slower speed in its orbit around the sun. That means that the Earth will pass it, and that will give the effect that the planet is moving backward. That same scenario can be seen between two cars on a highway, the faster car will see the slower car when it passes going in backward for a short fragment of time.
Remember that all the object in the night sky moves from east to west (since the Earth rotates counterclockwise in its daily movement), in the case of a planet with retrograde motion, it will move from west to east for a couple of months.
Answer:
the first one by using second person point of view
The free-body diagram of your question is; 2 downward forces (253 kg mass of barbell & 133 kg body mass of Kurlovich) acting together on a point supported by 2 upward forces as normal forces exerted by Kurlovich's feet.
Solving the normal forces exerted by 2 feet :
Summation of Forces Vertical = 0
2 Dowwnard Forces = 2 Upward Forces (2F)
253 + 133 = 2F
2F = 386 Kgs
F = 386 / 2
F = 193 Kgs (Normal Force Exerted by Each Foot)
