Q. As the initially empty urinary bladder fills with urine and expands, its internal pressure increases by 2700Pa, which triggers the maturation reflex (the feeling of the need to urinate). A horizontal square section of the bladder wall with an edge length of 0.01m. Since the bladder is stretched, four tension forces of equal magnitude T act on the square section, one at each edge, and each force is directed at an angle θ below the horizontal. What is the magnitude T of the tension force acting on one edge of the section while the internal bladder pressure is 2700Pa and each of the four tension forces is directed 6.4° below the horizontal?
A toy of mass 0.155 kg is undergoing SHM on the end of a horizontal spring with forces constant 305 N/m. When object is a distance 1.20×10-2 m from its equilibrium position, it is observed to have the speed of 0.255 m/s.
Estimate the ball's rise in temperature.
The force on a particle is directed along an x axis and given by F = 0.97(x/4.6 - 0.52) where x is in meters and F is in Newtons. Find out the work done by the force in moving the particle from x = 0 to x = 8.9 m.
