Brain injuries generally occur any time the brain's acceleration reaches 100 g for even a short time, Consider a car running into a solid barrier
A 3.57 kg block is drawn at constant speed 4.06 m along a horizontal floor by a rope exerting a 7.68 N force at angle of 15 degree above the horizontal. Work out the coefficient of kinetic friction between block and floor.
The length of a table in the laboratory was measured as 182.36 cm, What is the relative uncertainty of the length, What is the uncertainty of the length
A collimated beam of microwaves impinges on a metal screen that contains a long horizontal slit that is 20cm wide. A detector moving parallel to the screen in the far-field region locates first minimum of irradiance at an angle of 36.8° above the ..
