Venus has a surrounding that is approximately one hundred instances thicker than Earth's and has surface temperatures that are extraordinarily hot. Venus no longer has life or water oceans as Earth does.
Venus additionally rotates backward in comparison to Earth and the alternative planets. The geology of Earth is dominated by plate tectonics, Venus has "blob tectonics," wherein the growing of hot material from inside performs a dominant position in sculpting its surface. Venus is also one-of-a-kind from Earth in having miles decrease stage of erosion, because no precipitation and surface wind speeds are very low.
Venus is often called "Earth's dual" because they're similar in size and structure, but Venus has severe floor heat and a dense, poisonous environment. If the sun have been as tall as a typical front door, Earth and Venus could never be about the scale of a nickel.

Answer:
The correct option is;
d) F, because the net force is equal to the mutual contact force between the blocks
Explanation:
The given information are
The mass of block A = m
The velocity of block A = +v
The mass of block B = 2·m
The velocity of block B = -v
Given that the two blocks collide, we have;
Initial total momentum = m × v + 2·m×(-v) = m·(v - 2·v) = -m·v
Final total momentum = m × v₁ + 2·m×v₂ = m·(v₁ + 2·v₂)
From the law of conservation of linear momentum, we have;
m·(v₁ + 2·v₂) = -m·v
v₁ + 2·v₂ = -v
Therefore, the resultant velocity of the two blocks is -v, and the direction of the block A is reversed and the resultant inertia is equivalent to the inertia of block A
Therefore;
The force exerted on block B = The force exerted on block A = The rate of change of momentum experienced by the two blocks = The mutual contact force experienced between the blocks.
