How is the tracking of a sunspot affected by the rotation of the earth?
The tracking of a sunspot affected by the rotation of the earth in the following ways:

How much torque would be necessary to bring the earth to a stop in its rotation about its own axis in 1 year?
2. The rotation of the earth might have an effect on g measured on the Earth. Let's imagine standing on a scale at a latitude on the Earth. Taking the rotation of the Earth into account, we want to evaluate the value of "g" that a scale would read that would be measured as the normal force from the scale (the apparent weight), to be m'g'. a. For a person standing at the north pole: i. Draw your free body...
The tidal forces between the Earth and the Moon slowed down the Moon's rotation about its own axis until the rotation period became equal to the Moon's orbital period around the Earth as we observe today. The same effect is also slowing down the Earth's rotation about its own axis and increasing the separation \(D\) between the Moon and the Earth at a rate of \(\Delta D / \Delta t=3.8 \mathrm{~cm}\) per year. In this problem, you can ignore the...
5. Describe how the cooling of the Earth affected the development of the continents, oceans, and atmosphere. 6. In the exercise, you labeled five periods of mass extinction on your time scale. Research the following questions: what are some proposed causes of these extinctions? Is the cause of any of the mass extinctions definitely known? Consider using Google Scholar instead of Goog le when researching this question, and consult your instructor on the rules of citation
Considering the rotation of the Earth only, compare your apparent weight on the North Pole and on the Equator.

Topic: Motion with Constant Angular Acceleration. 25.) The rotation of the Earth is slowing down. In 1977, the Earth took 1.01 s longer to complete 365 rotations than in 1900. What was the average angular deceleration of the Earth in the time interval from 1900 to 1977? Please show your complete solutions with explanation. Thank you.
A projectile is shot directly away from Earth's surface. Neglect the rotation of the Earth. What multiple of Earth's radius RE gives the radial distance (from the Earth's center) the projectile reaches if (a) its initial speed is 0.437 of the escape speed from Earth and (b) its initial kinetic energy is 0.437 of the kinetic energy required to escape Earth? (Give your answers as unitless numbers.)
A projectile is shot directly away from Earth's surface. Neglect the rotation of the Earth.
