Answer: The correct answer is : The critical density for the universe is approximately 10 ^ -26 kg / m ^ 3 or you can also say 10 hydrogen atoms per cubic meter.
Explanation: This value is given by:
critical density = 3H ^ 2/2 Pi G, where H is the Hubble constant and G is Newton's gravitational constant.
Critical density is the average density of matter necessary for the universe to stop its expansion but after an infinite time.

Answer:
In a typical behavior modification program, one needs to select a behavior to modify and describe it completely using concrete terms. Next, one must gather data about target behavior that includes identifying how many times the behavior occurs, identifying triggers, and the consequences that follow the behavior. Then, one should design a program that will both effectively change the behavior and track one's progress in doing so in order to increase wanted behavior or decrease unwanted behavior. Finally, the plan must be put into effect and watched to see whether or not it works. If it does not work, then the plan must be modified, or adjusted. Then the program should be brought to an end be reducing reinforcement gradually.

Nepal moved from unitary system with a three-level federal system of government. As federalism accelerates, the national health system can also speed up its own decentralization process, reduce disparities in access, and improve health outcomes. Federalism is a compromise meant to eliminate the disadvantages of both systems. In a federal system, power is shared by the national and state governments. The Constitution designates certain powers to be the domain of a central government, and others are specifically reserved to the state governments.
