Perform the calculation of the force acting between two 70 kg people standing 1 meter apart. What does stress measure in biomechanics? What is the acceleration due to gravity at an altitude of 1.00 x 10^6? What unit is used to measure electrical force? What is magnitude in...
Is it “obvious” that our simple process of adaptive evolution will be able to successfully “wrangle” things to achieve this? No. But the fact that it can seems to be at the heart of why biological evolution manages to work. Looking at the sequences o...
A man lifts a 15 kg crate directly upwards from the floor to a shelf (4 m high) at a constant speed. a. What is the work done by the man on the crate? b. What is the work done by gravity on the crate? How much work did the mo...
Chris Isham at Imperial College, London and Rafael Sorkin at Syracuse University – all work on the problem of quantum gravity, which is the attempt to bring gravity within the
A Gyro compass isa form of gyroscope, used widely on ships employing an electrically powered, fast-spinning gyroscope wheel and frictional forces among other factors utilizing the basic physical laws, influences of gravity and the Earth's rotation to find the true north. ...
A charged particle is moving through a constant magnetic field. Does the magnetic field do work on the charged particle? Which of the following is a contact force? A. electric B. friction C. gravity D. magnetic Does resultant force provide centripetal force?
Decantation relies on gravity to pull precipitate out of the solution, so there is always some loss of product, either from the precipitate not fully falling out of the solution or from liquid remaining when separating it from the solid portion. ...
Mouche asks me why it’s harder to go up than down, so I give him a lesson in the law of gravity. He flies down each hill, yelling, full of joy. On our way home we listen to the All Songs Considered podcast’s episode on John Prine, who died this week of COVID-19. Angel ...
