Protons in cosmic rays strike the earth's upper atmosphere at a rate ,...
Introduction:
Cosmic rays are high-energy particles, mainly protons, that originate from outer space and strike the Earth's atmosphere. In this scenario, we are given the rate at which protons in cosmic rays strike the Earth's upper atmosphere on average over the Earth's surface. We need to calculate the total current that the Earth receives from beyond its atmosphere in the form of incident cosmic ray protons.

Given:
- Rate of proton strikes: 10 protons m-2 s-1
- Radius of the Earth: 6.4 x 106 meters

Calculating the Total Current:

1. Calculating the Area:
The area over which the protons strike the Earth's upper atmosphere can be considered as the surface area of a sphere with a radius equal to the radius of the Earth. The formula for the surface area of a sphere is given by:
A = 4πr2
where A is the surface area and r is the radius.

Substituting the given radius value, we can calculate the surface area:
A = 4π(6.4 x 106)2

2. Calculating the Total Proton Strikes:
To calculate the total number of protons striking the Earth's upper atmosphere per second, we need to multiply the rate of proton strikes by the surface area of the Earth.
Total Proton Strikes = Rate of Proton Strikes × Surface Area

Substituting the given values, we get:
Total Proton Strikes = 10 protons m-2 s-1 × 4π(6.4 x 106)2

3. Calculating the Total Current:
The total current can be calculated by multiplying the total number of protons striking the Earth's upper atmosphere per second by the charge of a single proton (1.6 x 10-19 Coulombs).
Total Current = Total Proton Strikes × Charge of a Proton

Substituting the given values, we get:
Total Current = (10 protons m-2 s-1 × 4π(6.4 x 106)2) × (1.6 x 10-19 Coulombs)

Final Answer:
After performing the calculations, we obtain the total current that the Earth receives from beyond its atmosphere in the form of incident cosmic ray protons.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same: Earth’s magnetism: Earth’s magnetic field is caused by a dynamo effect. The effect works in the same way as a dynamo light on a bicycle. Magnets in the dynamo start spinning when the bicycle is pedaled, creating an electric current. The electricity is then used to turn on the light. This process also works in reverse. If you have a rotating electric current, it will create a magnetic field. On Earth, flowing liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet. The average magnetic field strength in the Earth's outer core was measured to be 25 Gauss, 50 times stronger than the magnetic field at the surface. The magnetic field is extremely important for sustaining life on Earth. Without it, we would be exposed to high amounts of radiation from the Sun and our atmosphere would be free to leak into space. This is likely what happened to the atmosphere on Mars. As Mars doesn’t have flowing liquid metal in its core, it doesn’t produce the same dynamo effect. This left the planet with a very weak magnetic field, allowing for its atmosphere to be stripped away by solar winds, leaving it uninhabitable. Based upon the study of lava flows throughout the world, it has been proposed that the Earth's magnetic field reverses at an average interval of approximately 300,000 years. However, the last such event occurred some 780,000 years ago.Which of the following statements is true?
