What is parallel universe.?? need a brief explanation.. ​

Answer»

A PARALLEL UNIVERSE IS ALSO KNOWN AS PARALLEL DIMENSIONExplanation:A parallel universe, also known as a parallel DIMENSION, alternate universe or alternate reality, is a hypothetical self-contained plane of existence, co-existing with one's own. The sum of all potential parallel universes that constitute reality is often called a “multiverse". While the three terms are generally synonymous and can be used interchangeably in most cases, there is sometimes an additional connotation implied with the term "alternate universe/reality" that IMPLIES that the reality is a VARIANT of our own, with some overlap with the similarly-named alternate history.MARK AS BRAINLIEST

Delhi is at a distance of 200 km from Ambala .Car A set out from Ambala at a speed of 30 km per hr and car B set out at same time from Delhi at a speed of 20 km per hr When they will meet each other ? What is the distance of meeting point from Ambala? ​

Answer» TION:let they MEET at X point between ambala and delhi distance travelled by car A = X SPEED of car A = 30 km/ hrtime = X÷30distance travelled by car B = 200 - X speed of car = 20 km/hr TIME = (200-X) ÷ 20time is equal in both cases as cars start travelling at the same time (200-X)÷20 = X÷30 X comes out to be 120 km the distance from ambala is 120 km

Select the correct answer. Marsha wants to do her part to limit her impact on human-led climate change. Which action would help Marsha meet her goal?

Answer»

C. Use a bike to COMMUTE to work instead of driving.This action would help Marsha meet her goal in order to limit her impact on human-led climate change.Explanation:If Marsha wants to do her part to limit her impact on human-led climate change, she should try to avoid things which adds global warming GASES to the atmosphere.1. If she buys a new car, she is literally adding carbondioxide to the atmosphere. It will lead to the climate change. So the option A is incorrect2. If she burns the trash instead of leaving it for city trash collection, she adds more hydrocarbons in the atmosphere which again will lead to climate change. So this option (B) is also incorrect3. If she uses a bike instead of driving, her carbon footprint is very low and she AVOIDS adding global warming gases to the atmosphere. Doing it, she LIMITS the human led climate change.4. If she buys a new Refrigerator, she is adding more fluorocarbon to the atmosphere which again will lead to climate change. So this option (D) is also incorrect.plz Mark as the brainliest answer or follow me plz plz.

what is the effect of atomic number and mass number when Alpha particle and beta particle are emitted from a radioactive nucleus?​

Answer»

tion:Not all elements undergo nuclear decay over timescales that we can observe. Some elements take millions of years to decay. In fact, most living things primarily consist of isotopes of CARBON and nitrogen, which have such incredibly long lifetimes that they will essentially never decay within the lifespan of the organism. This is necessary because the biochemical function of each of these atoms is specifically tied to its atomic number: if a nervous receptor specifically seeks out and binds a carbon-based signalling molecule, then it won’t work if that carbon spontaneously changes into beryllium.Different atoms of the same element can have different masses. For example, an atom of carbon (atomic number 6, so six protons) can have either 6 neutrons or 8 neutrons. The former case is more familiar from chemistry class, since a lot of the common light elements used in biology (like oxygen, carbon, and nitrogen) have the same number of protons as neutrons. But it TURNS out that the case of carbon having 6 protons and 8 neutrons, while not as stable as 6 and 6, is stable enough that it can actually occur in nature in OBSERVABLE amounts. Because the 8 neutron nucleus and the 6 neutron nucleus are technically both carbon, we call them different isotopes of carbon.Since protons and neutrons have ROUGHLY the same mass, the more common version of carbon is called carbon-12 (6 protons + 6 neutrons). The heavier isotope is called carbon-14 (6 protons + 8 neutrons). But when you look up the mass of carbon on the periodic table, it says that the mass is 12.011 atomic mass units (amu). This is because if you went out and weighed a huge batch of carbon atoms, most of the atoms you would find would weigh exactly 12 amu. But within that huge batch you’d occasionally find a carbon-14 nucleus, which would skew the average of your measurements to a value slightly higher than 12.For reasons that are deeply related to the fundamental forces that act in the nucleus, the tendency of a substance to undergo nuclear decay is related to both the atomic number and the atomic mass of an element. This means that two different isotopes of the same element will have different tendencies to undergo nuclear decay. In the case of carbon, the isotope carbon-14 wants to decay into nitrogen while carbon-12 (which is most of the carbon in your body) would remain stable.As a result, knowing which isotope is present in a sample of element not only tells US the sample’s stability, but also the type of decay it will undergo.

Answer»

ber of years after which the 2 nuclei will have the same activity is 60Number of Nuclei at a time is given by N =N0. at t = T, half life period, N = N0/2 N/N0  = = 1/2natural LOG, LN(1/2) = -LTln 2 = LT ==> L = 0.693/TLet L be the DECAY constant and T be the half lifeIf a and b are the 2 nuclei,La = 0.693/Ta and Lb = 0.693/TbLa = 0.03465 , Lb = 0.0462Activity of the nuclei is given by R =   = -LN0 = -LN.Therefore given ratio of initial activities: = To find the time when both have equal activity,Ra = Rb -LaNa(0) = -LbNb(0)rearranging ==> ln 2 = (Lb - La)t==>t = ln 2/ (Lb - La) = ln 2/(0.0462 - 0.03465) = 60 years
