The correct Answer is:
To solve the question regarding the changes in quantities for a satellite moved from one stable circular orbit to another larger stable circular orbit, we will analyze each quantity step by step. ### Step 1: Understanding Gravitational Potential Energy The gravitational potential energy (U) of a satellite in orbit can be expressed as: \[ U = -\frac{G M m}{r} \] where: - \( G \) is the gravitational constant, - \( M \) is the mass of the Earth, - \( m \) is the mass of the satellite, - \( r \) is the distance from the center of the Earth to the satellite. **Hint:** Remember that gravitational potential energy is negative and inversely proportional to the distance \( r \). ### Step 2: Analyzing the Change in Gravitational Potential Energy When the satellite moves to a larger orbit, the value of \( r \) increases. Since gravitational potential energy is inversely proportional to \( r \), as \( r \) increases, the absolute value of \( U \) decreases, but since it is negative, this means that \( U \) becomes less negative (i.e., increases). **Conclusion for Step 2:** Gravitational potential energy increases. ### Step 3: Understanding Angular Velocity The angular velocity (\( \omega \)) of a satellite in a circular orbit can be given by: \[ \omega = \sqrt{\frac{G M}{r^3}} \] **Hint:** Angular velocity is related to the radius of the orbit. ### Step 4: Analyzing the Change in Angular Velocity From the formula, we can see that angular velocity is inversely proportional to the square root of \( r^3 \). As \( r \) increases, \( \omega \) will decrease. **Conclusion for Step 4:** Angular velocity decreases. ### Step 5: Understanding Linear Orbital Velocity The linear orbital velocity (\( V \)) can be expressed as: \[ V = \sqrt{\frac{G M}{r}} \] **Hint:** Linear velocity is also dependent on the radius of the orbit. ### Step 6: Analyzing the Change in Linear Orbital Velocity Similar to angular velocity, linear orbital velocity is inversely proportional to the square root of \( r \). Therefore, as \( r \) increases, \( V \) will also decrease. **Conclusion for Step 6:** Linear orbital velocity decreases. ### Step 7: Understanding Centripetal Acceleration Centripetal acceleration (\( a_c \)) can be expressed as: \[ a_c = \frac{V^2}{r} = \frac{G M}{r^2} \] **Hint:** Centripetal acceleration is related to the radius squared. ### Step 8: Analyzing the Change in Centripetal Acceleration From the formula, centripetal acceleration is inversely proportional to \( r^2 \). As \( r \) increases, \( a_c \) will decrease. **Conclusion for Step 8:** Centripetal acceleration decreases. ### Final Conclusion After analyzing all the quantities: - Gravitational potential energy increases. - Angular velocity decreases. - Linear orbital velocity decreases. - Centripetal acceleration decreases. Thus, the only quantity that increases when the satellite is moved to a larger stable circular orbit is **gravitational potential energy**. ### Answer The correct answer is: **Gravitational potential energy increases.**

To solve the question regarding the changes in quantities for a satellite moved from one stable circular orbit to another larger stable circular orbit, we will analyze each quantity step by step. ### Step 1: Understanding Gravitational Potential Energy The gravitational potential energy (U) of a satellite in orbit can be expressed as: \[ U = -\frac{G M m}{r} \] where: - \( G \) is the gravitational constant, - \( M \) is the mass of the Earth, ...
