Physics teacher | Experienced educator in USA

I hold a degree in Physics from The American College of Financial Services. With a passion for unraveling the mysteries of the universe, I bring a deep understanding of physics concepts to my teaching. From classical mechanics to quantum theory, I strive to make complex topics accessible and engaging for my students. With a dedication to fostering a supportive learning environment, I aim to empower students to excel in their academic pursuits and develop a lifelong love for physics. Let's explore the wonders of the universe together.

## Questions

A ball with a mass of #80 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #9 (kg)/s^2# and was compressed by #3/5 m# when the ball was released. How high will the ball go?

What is the relationship between acceleration and speed?

In parallel RC circuits, is it true that the larger the value of C, the larger the phase angle?

A cylinder has inner and outer radii of #9 cm# and #14 cm#, respectively, and a mass of #9 kg#. If the cylinder's frequency of counterclockwise rotation about its center changes from #5 Hz# to #7 Hz#, by how much does its angular momentum change?

If the length of a #2 cm# spring increases to #6 cm# when a #3 kg# weight is hanging from it, what is the spring's constant?

Quick explanation. An object will stay afloat as long as it weighs less than or equal to its displaced fluid weight in water?

What is the difference between angular momentum and linear momentum?

How would you evaluate #(5.7×106 kg) × (6.3×10−2 m/s2)# and express the answer in scientific notation?

An object, previously at rest, slides #7 m# down a ramp, with an incline of #(pi)/3 #, and then slides horizontally on the floor for another #12 m#. If the ramp and floor are made of the same material, what is the material's kinetic friction coefficient?

Explain thermal expansion of water?

What is the cross product of #[3,2, 5]# and #[1,2,-4] #?

A balanced lever has two weights on it, the first with mass #3 kg # and the second with mass #2 kg#. If the first weight is # 4 m# from the fulcrum, how far is the second weight from the fulcrum?

Are sound waves a part of an electromagnetic spectrum?

A spring is hung vertically. It is loaded with 50 g mass and allowed to oscillate. Calculate the frequency of oscillation when the spring is loaded with 150 g which exceeds 100m?

Can anyone confirm the answer I have to this question?

If a #1 kg# object moving at #1 m/s# slows down to a halt after moving #1 m#, what is the friction coefficient of the surface that the object was moving over?

A charge of #-1 # #C# is at the origin. How much energy would be applied to or released from a # 3# #C# charge if it is moved from # (1, 6 ) # to #( 2 , -4) #?

A charge of #4 C# is passing through points A and B on a circuit. If the charge's electric potential changes from #27 J# to #11 J#, what is the voltage between points A and B?

An object with a mass of #200 g# is dropped into #300 mL# of water at #0^@C#. If the object cools by #72 ^@C# and the water warms by #3 ^@C#, what is the specific heat of the material that the object is made of?

What does resonance frequency mean?
