There are multiple reasons why and MRI scan as a diagnostic tool can be considered inappropriate. The primary reason other diagnostics are used over MRI is because of cost-effectivity. The MRI scan is considerably more expensive compared to x-rays and CT scans. It would be inappropriate to ask for an MRI when the symptoms point to a simple bone fracture of the leg for example. An x-ray can give you the same amount of information in this regard without the huge cost of an MRI.
Another example would be if the patient is claustrophobic. Taking an MRI scan takes a long time and it would involve inserting the patient in a coffin-like machine. Getting an image would be impossible because the patient would need to hold still for a span of 40 minutes to 1 hour.
most of a atoms mass is in the nucleus of the atom:) hope this helps you
1. Physical properties of the planets vary in a systematic fashion as a function of distance from the Sun.
Planets and Sun revolve and orbit in a west-to-east direction. The planets obliquity (tilt of rotation axes to their orbits) are small. Uranus and Venus are exceptions.
The planets differ in composition. Their composition varies roughly with distance from the Sun: dense, metal-rich planets are in the inner part and giant, hydrogen-rich planets are in the outer part.
The Moon include its distance from the Earth, size, mass, density, and temperature
2. Asteroids - large, rocky bodies
Comets -
smaller, made of ice, rock, dust
I don't know if this is what you want, but please please correct me if I'm wrong!! :)
