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.

Direct touch with the lymph node material flowing from an infected cat might also expose people to the sickness. Yersinia pestis can be spread to humans by fleas carried by an infected cat biting them. If a cat has pneumonic plague, it is very simple for humans to contract it through the air.

What is plague?</h3>
The bacterium Yersinia pestis is the source of the infectious disease known as plague. Fever, weakness, and headache are symptoms. Within one to seven days of exposure, this usually starts. There are three types of plague, each of which affects a different body part and produces corresponding symptoms. Bubonic plague affects the lymph nodes, causing them to enlarge, whereas septicemic plague infects the blood and has the potential to cause tissues to turn black and die. Pneumonic plague affects the lungs, causing shortness of breath, coughing, and chest pain.While the pneumonic plague is typically communicated between people through the air via infectious droplets, the bubonic and septicemic variants are typically spread by flea bites or handling an infected animal.
