The solar constant is the amount of heat energy received per second per unit area of a perfectly black surface placed at a mean distance of the Earth form the Sun, in the absence of Earth's atmosphere, the surface being held perpendicular to the direction of Sun's rays. Its value is 1388 W//m^(2) . If the solar constant for the earth is 's'. The surface temperature of the sun is TK,D is the diameter of the sun, R is the mean distance of the Earth from the sun. The sun subtends a small angle 'theta' at the earth. Then correct options is/are:-

Assuming the sun to have a spherical outer surface of radius r radiating like a black body at temperature t^(@)C . The power received by a unit surface (normal to the incident rays) at a distance R from the centre of the sun is where sigma is the Stefan's constant.

The ratio of radiant energies radiated per unit surface area by two bodies is 16 : 1 , the temperature of hotter body is 1000 K , then the temperature of colder body will be

Surface tension is the property of a liquid by virtue of which the free space of the liquid at rest tends to have minimum area and as such it behaves as if covered with a stretched membrane. It is measured as the force acting an unit length of a line imagined to be drawn tangentially anywhere on the free surface of liquid at rest. It acts at right angles to this line on both sides and along the tangent to the liquid surface. When a razor bladed floats on water, then the force of surface tension acts on the circumference of the blade acting tangentially to the liquid surface : (a) True (b) False

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 of 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 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 followings is the reason for Earth's magnetism? Which planet has no own magnetic field ?
