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
What is the relationship between velocity and distance?

Some very hot rocks have a temperature of #460 ^o C# and a specific heat of #270 ( kJ)/(kg)#. The rocks are bathed in #108 L# of boiling water. If the heat of the rocks completely vaporizes the water, what is the minimum combined mass of the rocks?
A ball with a mass of #2 kg # and velocity of #8 m/s# collides with a second ball with a mass of #4 kg# and velocity of #- 1 m/s#. If #15%# of the kinetic energy is lost, what are the final velocities of the balls?
A ball with a mass of #1 kg # and velocity of #6 m/s# collides with a second ball with a mass of #1 kg# and velocity of #- 3 m/s#. If #20%# of the kinetic energy is lost, what are the final velocities of the balls?
