At $2,600 on average for an MRI and $1,100 on average for an ultrasound, even one unnecessary test is too many for folks on a budget, unless your insurance or Medicare covers the test.or example, the cost of a CT scanner can be as low as $65,000 for a refurbished one that produces only small images quickly. A larger and brand new CT scanner can run as high as $2.5 million. Prices are slightly higher for MRI machines, running up to about $3 million for a new machine.
1. constant of proportionality-the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality. factor of proportionality.
Force constant mainly means spring constant in physics, which ultimately refers to Hooke's law Hooke's law is a principle of physics that states that the force (F) needed to extend or compress a spring by some distance X is proportional to that distance. That is: F = kX, where k is a constant factor characteristic of the spring: its stiffness, and X is small compared to the total possible deformation of the spring.
