<span>Good Morning!
The scientific advance that launched an ethical alert in the scientific community was the possibility of cloning animals, since it presents important questions, especially if such a project is extended to humans.

The car is the heaviest object there and mass is proportional to force, meaning the heavier it is the bigger the force should be in order to move it.
Answer:
Tension, T = 0.1429 N
Explanation:
Given that,
Mass of the rock, m = 0.0450 kg
Radius of the circle, r = 0.580 m
Angular speed,
The tension in the string is balanced by the centripetal force acting on it. It is given by :
Since,
T = 0.1429 N
So, the tension in the string is 0.1429 N. Hence, this is the required solution.
Answer:
greatest speed=0.99c
least speed=0.283c
Explanation:
To solve this problem, we have to go to frame of center of mass.
Total available energy fo π + and π - mesons will be difference in their rest energy:
=218 Mev
now we have to assume that both meson have same kinetic energy so each will have K=109 Mev from following equation for kinetic energy we have,
K=(γ-1)
note +-=±
To find speed least and greatest speed of meson we would use relativistic velocity addition equations:
Answer: The answer is C. Yes
Explanation: The friction force is the force that opposes any object moving. Anything that moves on any surface do have a frictional force.
