I hold a degree in Physics from Eastern Mennonite University. With a passion for unraveling the mysteries of the universe, I thrive on sharing my knowledge with students. From classical mechanics to quantum theory, I offer clear explanations and engaging lessons to foster deep understanding. Let's explore the wonders of physics together, tackling questions across various subjects.
Questions
Which has more momentum, a #5kg# object moving at #8m/s# or a #12kg# object moving at #2m/s#?
An object with a mass of # 8 kg# is on a ramp at an incline of #pi/8 #. If the object is being pushed up the ramp with a force of # 7 N#, what is the minimum coefficient of static friction needed for the object to remain put?
A brass plug is to be placed in a ring made of iron. At room temperature, the diameter of the plug is 8.753 cm and that of the inside of the ring is 8.743 cm. They must both be brought to what common temperature in order to fit?
The position of an object moving along a line is given by #p(t) = t^3 - 2t +2#. What is the speed of the object at #t = 1 #?
Water flows through a fire hose of diameter 6.35 centimeters at a rate of 0.012 m3/s. the fire hose ends in a nozzle of inner diameter 2.2 centimeters. what is the velocity with which the water exits the nozzle?
55,000J of work is done to move a rock 25m. How much force was applied?
How much work would it take to push a # 2 kg # weight up a # 9 m # plane that is at an incline of # pi / 4 #?
How do you calculate the mechanical advantage of a second-class lever?
The force applied against an object moving horizontally on a linear path is described by #F(x)= x^2 + x N #. By how much does the object's kinetic energy change as the object moves from # x in [ 1 , 2 ]#?
A branch falls from a tree. How fast is the branch moving after 0.28 seconds?
How much power is produced if a voltage of #6 V# is applied to a circuit with a resistance of #12 Omega#?
Why is electric force represented as a vector?
The force applied against an object moving horizontally on a linear path is described by #F(x)= 4x^2+x #. By how much does the object's kinetic energy change as the object moves from # x in [ 0, 4]#?
A particle of mass m is acted on by a force F and is accelerating at 8m/S. Are there calculations correct?
I have a device that needs #12"V"# and #2"A"# to run. I have a #28"V"# source. How do I make the device work with one or more #3Omega# resistors?
What is the cross product of #<7, 2 ,5 ># and #<-3 ,1 ,-6 >#?
The gas inside of a container exerts #4 Pa# of pressure and is at a temperature of #220 ^o C#. If the temperature of the gas changes to #150 ^oK# with no change in the container's volume, what is the new pressure of the gas?
A charge of #16 C# is passing through points A and B on a circuit. If the charge's electric potential changes from #38 J# to #12 J#, what is the voltage between points A and B?
A container with a volume of #5 L# contains a gas with a temperature of #320^o K#. If the temperature of the gas changes to #250^o K# without any change in pressure, what must the container's new volume be?
