About how much longer can the Sun continue to generate energy by nuclear reactions in its core?

Physics
1 answer:
QveST [7]4 years ago
5 0

Answer: 5billion years

Explanation: The sun produces energy through radioactive fusion reaction.

Nebula theory states that the gaseous particles of the Earth collapsed as a result of its own gravity which continuously lead to fusion reaction for the production of nuclear energy.

The Core of the Sun is that area up to 25% from the radius of the sun,here the pressure here range up to 250million atmosphere containing mainly hydrogen which gets converted in Helium molecule. The core is the center for energy production accounting for more than 98%, nuclear energy is transmitted at about 4.3million metric tons per second.

The resistance 2 Ω, 4 Ω and 8 Ω are connected in parallel. Their equivalent
Zigmanuir [339]

Answer:

The answer to your question is the letter B. R = 8/7 Ω

Explanation:

Data

R1 = 2 Ω

R2 = 4Ω

R3 = 8Ω

To calculate the total resistance use the formula

         1/R = 1/R1 + 1/R2 + 1/R3

-Substitution

         1/R = 1/2 + 1/4 + 1/8

- Look for the Greatest common factor

              2   4   8    2

               1   2    4   2

                    1    2   2

                          1

The GCF = 2 x 2 x 2 = 8

-Sum up the fractions

                 1/2 + 1/4 + 1/8 = (4 + 2 + 1) / 8

                                        = 7/8

-Find R

               1/R = 7/8    then, R = 8/7 Ω

Was work done on a book that fell from a desk to the floor? If so, what force was involved?
IgorLugansk [536]
Sure ! 
The work is (weight of the book) x (height of the desk above the floor).
The force (weight) is the result of gravity.
It was gravity that did the work.

the inductive reactance of a 20.0-mh inductor at a certain frequency is 120 ω. what is the frequency in hz?
QveST [7]

The inductive reactance of a 20.0-mh inductor at a certain frequency is 120 ω. 955hz is the frequency in hz

In physics, frequency is the number of waves that pass a fixed point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time.

How frequently something occurs is what is meant by the word frequency. A person blinking their eyelids 47 times in a minute is an example of frequency. the quality or state of happening frequently.

Frequency is a numerical value that expresses how frequently a specific item appears in the supplied data set. Grouped frequency distribution and Ungrouped In physics, frequency is a numerical value that expresses how frequently a specific item appears in the supplied data set. Distribution are the two different types of frequency tables.
