The best answer is B)
Space technology helps improve life on Earth.
Many of the innovations developed by space programs had applicability beyond their original use. This is one such example, in which robotic technology used for servicing spaceships is helping to improve surgeries here on Earth.
- We know, acceleration is the change of velocity by time.
- Velocity is the speed of an object which also indicates the direction.
- Hence, acceleration is both dependant upon the speed as well as the direction.
- So, if an object is moving at a constant speed in a changing direction, the acceleration will also change. It will not be zero.
- An example is that of uniform circular motion.
Answer:
if an object is moving at a constant speed in a changing direction, the acceleration of the object will not be zero.
Answer:
0.46km
