The binding energy of a satellite can be defined as the minimum amount of energy required to be supplied to it in order to free the satellite from the gravitational influence of the planet (i.e. in order to take the satellite from the orbit to a point at infinity).
What is binding energy of satellite find its value?
r 1 = R + h 1 = 6400 + 600 = 7000 km = = 7 x 10 6 m; Ans: Binding energy of satellite orbiting very close to the earth’s surface is 6.25 x 10 10 J and binding energy of satellite orbiting at height 600 km from the surface of the earth is 5.72 x 10 10 J.
What is binding energy of satellite class 11?
Binding energy is the minimum amount of energy required to free an object from a bound system and escape from its region of influence (i.e. escape to infinity) . In the given case, it is the energy required by the satellite to leave its orbit around the earth and escape to infinity.
What is the formula for binding energy of satellite?
The sum of the kinetic energy and potential energy of the satellite is its total energy called the binding energy of the satellite. Therefore, the binding energy (B.E) of the satellite will be equal to K+U . This implies, $E.B=K+U=dfrac{1}{2}dfrac{GmM}{r}-dfrac{GmM}{r}=-dfrac{1}{2}dfrac{GmM}{r}$ .
What is the meaning of binding energy?
Binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system . Binding energy is especially applicable to subatomic particles in atomic nuclei, to electrons bound to nuclei in atoms, and to atoms and ions bound together in crystals.
What is value of G and G at the Centre of Earth?
| Location Distance from Earth’s center (m) Value of g (m/s 2 ) | Earth’s surface 6.38 x 10 6 m 9.8 | 1000 km above surface 7.38 x 10 6 m 7.33 |
|---|
What do you mean by geostationary satellite?
Satellite that appears to be located at a fixed point in space when viewed from the earth’s surface . Satellites located in geosynchronous orbit move in time with the rotation of the earth. Geostationary satellites are located 22,237 miles above the earth’s surface.
What is the binding energy of Earth?
For the Earth, the Gravitational Binding Energy is about 2×10 32 Joules , or about 12 days of the Sun’s total energy output! For objects of the same Mass but different Radii, the larger object (bigger radius) will have: Slower circular and escape speeds. Less gravitational binding energy (“less tightly bound”)
What is a geostationary satellite and what are its characteristics?
A geostationary satellite is in an orbit that can only be achieved at an altitude very close to 35,786 km (22,236 miles) and which keeps the satellite fixed over one longitude at the equator. The satellite appears motionless at a fixed position in the sky to ground observers .
What is the binding energy of a satellite of mass 80 kg?
2. 5×109J .
What is binding energy in physics gravitation?
The gravitational binding energy of a system is the minimum energy which must be added to it in order for the system to cease being in a gravitationally bound state.
What is the significance of negative total energy?
The energy of an electron at infinity is arbitrarily assumed to be zero . this state is called zero energy state. When an electron moves and comes under the influence of nucleus, it does some work and spends its energy in this process.
What is binding energy topper?
Binding energy and binding energy per nucleon – definition
If a certain number of neutrons and protons are brought together to form a nucleus of a certain charge and mass, an energy Eb will be released in the process. The energy Eb is called the binding energy of the nucleus. Eb=ΔMc2 .
What causes binding energy?
The electron binding energy derives from the electromagnetic interaction of the electron with the nucleus and the other electrons of the atom, molecule or solid and is mediated by photons. ... The atomic binding energy of the atom is the energy required to disassemble an atom into free electrons and a nucleus.
How do you get binding energy?
Once mass defect is known, nuclear binding energy can be calculated by converting that mass to energy by using E=mc 2 . Mass must be in units of kg. Once this energy, which is a quantity of joules for one nucleus, is known, it can be scaled into per-nucleon and per-mole quantities.
Is binding energy negative or positive?
Nuclear binding energy is the minimum energy that is required to disassemble the nucleus of an atom into its constituent protons and neutrons, known collectively as nucleons. The binding energy for stable nuclei is always a positive number , as the nucleus must gain energy for the nucleons to move apart from each other.
