SPACS 113: Stars, Galaxies and the Universe

Unlock the secrets of calculating electric charge using Coulomb's Law and discover the fascinating world of electrostatic forces. Learn how to determine the charge on two spheres, spaced 20.0 cm apart, and understand the role of elementary particles in this physics tutorial.

In this enlightening video, we unravel the mysteries of electric charges and forces. Discover the fascinating concept of how the separation between two identical tiny spheres, each carrying the same electric charge, influences the force they exert on each other. Will the force double, become one-quarter as large, or remain unchanged? Join us to explore the intriguing world of electrostatics and the principles that govern electric interactions.

Explore the intriguing interplay of electric fields and conductors in this video. We examine how the presence of a point charge inside or outside a conductor affects the electric field. Join us to unravel the principles of electrostatics.

Explore the concept of capacitance in a spherical capacitor and learn how to calculate it. Discover how to find the plate area for a parallel-plate capacitor with the same capacitance and separation.

Explore Earth's dimensions in this video! We calculate its circumference, surface area, and volume. Join us to understand the scope of our planet, both in its physical size and mathematical concepts.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.
