Amelia Adams
Physics teacher | Tutor for 8 years
With a passion for unraveling the mysteries of the universe, I hold a degree in Physics from Illinois Wesleyan University. I'm dedicated to fostering a deeper understanding of the cosmos through engaging teaching methods. Whether it's classical mechanics or quantum theory, I strive to make complex concepts accessible to all students. My goal is to inspire curiosity and ignite a lifelong love for learning in each individual I teach. Together, let's explore the wonders of the physical world.
Questions
Objects A and B are at the origin. If object A moves to #(-2 ,8 )# and object B moves to #(-5 ,-6 )# over #4 s#, what is the relative velocity of object B from the perspective of object A?
The gas inside of a container exerts #32 Pa# of pressure and is at a temperature of #90 ^o K#. If the temperature of the gas changes to #80 ^oK# with no change in the container's volume, what is the new pressure of the gas?
An object with a mass of #180 g# is dropped into #720 mL# of water at #0^@C#. If the object cools by #24 ^@C# and the water warms by #9 ^@C#, what is the specific heat of the material that the object is made of?
A solid disk, spinning counter-clockwise, has a mass of #2 kg# and a radius of #8/9 m#. If a point on the edge of the disk is moving at #11/4 m/s# in the direction perpendicular to the disk's radius, what is the disk's angular momentum and velocity?
The force applied against an object moving horizontally on a linear path is described by #F(x)= sinpix +2 #. By how much does the object's kinetic energy change as the object moves from # x in [ 2, 5 ]#?
A student drops his textbook out of a window in a tall building. How high above the ground is the book when it is falling at a speed of 438 cm/s?
The rate of rotation of a solid disk with a radius of #5 m# and mass of #5 kg# constantly changes from #11 Hz# to #24 Hz#. If the change in rotational frequency occurs over #1 s#, what torque was applied to the disk?
The force applied against an object moving horizontally on a linear path is described by #F(x)=xe^x+ 1/x #. By how much does the object's kinetic energy change as the object moves from # x in [ 1, 3 ]#?
If the length of a #34 cm# spring increases to #45 cm# when a #5 kg# weight is hanging from it, what is the spring's constant?
Some very hot rocks have a temperature of #220 ^o C# and a specific heat of #160 J/(Kg*K)#. The rocks are bathed in #90 L# of boiling water. If the heat of the rocks completely vaporizes the water, what is the minimum combined mass of the rocks?
What torque would have to be applied to a rod with a length of #5 # and a mass of #5 kg# to change its horizontal spin by a frequency of #3 Hz# over #4 s#?
Are sunglasses lenses linearly polarized?
An object with a mass of #6 kg#, temperature of #173 ^oC#, and a specific heat of #19 J/(kg*K)# is dropped into a container with #32 L # of water at #0^oC #. Does the water evaporate? If not, by how much does the water's temperature change?
Objects A and B are at the origin. If object A moves to #(-8 ,-5 )# and object B moves to #(-1 ,4 )# over #3 s#, what is the relative velocity of object B from the perspective of object A? Assume that all units are denominated in meters.
The gas inside of a container exerts #9 Pa# of pressure and is at a temperature of #35 ^o K#. If the temperature of the gas changes to #80 ^oK#, what is the new pressure of the gas?
A solid disk, spinning counter-clockwise, has a mass of #6 kg# and a radius of #2 m#. If a point on the edge of the disk is moving at #5/2 m/s# in the direction perpendicular to the disk's radius, what is the disk's angular momentum and velocity?
