How Do You Calculate Earth's Angular Velocity in Its Orbit?

Click For Summary
To calculate Earth's angular velocity in its orbit around the sun, the radius of the orbit is given as 1.5*10^11 meters. The key to solving the problem lies in using the period of Earth's orbit, which is one year, to determine the angular velocity. The angular velocity can be calculated using the formula ω = 2π/T, where T is the orbital period in seconds. By converting one year into seconds, the angular velocity can be expressed in radians per second. Understanding the relationship between period, radius, and angular velocity is crucial for solving this problem.

The extra thing to use in this problem is that you know the period of the motion (the time to make one complete revolution). Do you see how to use that to find the velocity and angular velocity?
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
