Answer:A how to build a computer program that simulates the movement of softbots
B all the different tasks robots could perform
C all the different materials robots could be made of
D all the different ways robots could move
all the different ways robots could move
Answer: Option D.
Explanation:According to group of researchers at the Cornell university thinks that the time that is to come is the time of the robots where the major tasks of the life of the humans will be taken up by the robots.
They also think that the robots that are to come up in the future are going to be a kind of softbots which are going to be made up of the soft tissues and would be more flexible to move compared to the other robots which exist already.
Answer:
v = 0.352 m/s
Explanation:
To calculate escape velocity,
( P.E. + K.E ) at the surface of the asteroid = ( P.E. + K.E ) at the infinity
Here infinity is refered as the point wjich does not feel the gravitational potential of the asteroid,
For minimum velocity the K.E at infinity = 0
-GMm/r² + = 0 + 0
v² = 2GM/r² = 2 × 6.674×10⁻¹¹×7.2×10¹⁶/(8800)²
v = 0.352 m/s
