Isabella Alvarez
Physics teacher | Tutor for 10 years
I hold a degree in Physics from New Mexico Tech. With a passion for unraveling the mysteries of the universe, I thrive on sharing my knowledge with curious minds. Through interactive sessions, I simplify complex concepts, making physics accessible and engaging for students. Whether it's classical mechanics or quantum theory, I foster a supportive environment where questions are encouraged and critical thinking flourishes. My goal is to inspire a lifelong love of learning and empower students to explore the wonders of science. Let's embark on a journey of discovery together!
Questions
An object, previously at rest, slides #8 m# down a ramp, with an incline of #pi/4 #, and then slides horizontally on the floor for another #5 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?
In electrical insulators, why are the electrons not free to move unlike in conductors? Is it due to stronger bonds or attraction between nucleus and electron?
How fast will an object with a mass of #15 kg# accelerate if a force of #32 N# is constantly applied to it?
Why is laser light special?
What is the underlying reason why harmonics sound good?
How does kinetic molecular theory explain the Charles' law?
