Why does the length of a fetus increase more rapidly than the mass of a fetus?

Because brain has to grow. The nervous system including the brain does not continue to develop through out the life of the organism. It has an initial period of grow during the adolescence and then there is no more development (creation of new brain cells). In addition there is a critical window of development where if the organism is denied full sensory input function will be never develop. These experiments were done by sewing an eye shut in a newborn rat then looking at the brain. Since the size of a young child's brain is the same as that of an adult brain the head will be disproportionately larger.
Why does the brain cease developing? Not really known, but perhaps because the ability to learn is not dependent on new cells, but on new connections within the brain. Adding new cells is not enough as they would have to send out axons to the right places. This doesn't work in vivo as the myelin prevents axon passage.
So the metaphor is that we have small little microchips that work well if they have no errors in the manufacturing process, but if there were errors in the manufacturing process it is easier to discard the entire chip than to try to fix one part of it. Unfortunately our brains are like that microchip. If it develops properly then it is good for our entire lives, if not we are discarded by the evolutionary process.
Maybe because the brain needs to be ready for the baby when it has is born, but all other organs in different parts of the body can develop over time.? over the time the bones and other orgas get large because the body grows.in the other hand the brain only grows for a short peried of time.

Why does the mass of the placenta increase as the fetus develops?
to hold the foetus thts growing.
What is the effect of changig length or mass of pendulum on value of g?
Changing the length will increase its period. Changing the mass will have no effect.
Cloud the pendulum be changed to increase the period of the pendulum?
Yes. You can increase the period by moving the pendulum to a location where the gravitational force is weaker.Alternatively, you can increase the effective length of the pendulum. The pendulum may be of fixed length, but you can still increase its effective length by adding mass to any point below its centre of gravity.Yes.

How does the assembly line benefits consumers?
it allowed the production for the product to increase rapidly. Therefore causing mass production and the price to go down
Do you increase or decrease in mass?
you increase or decrease mass by taking the mass out
What is a mass of rapidly growing tissue?
Tumor.
How do you calculate the length of steel in kg?
Kilogram is a unit of mass, not of length.Kilogram is a unit of mass, not of length.Kilogram is a unit of mass, not of length.Kilogram is a unit of mass, not of length.
What happens to moment of inertia of thin rod when its length is doubled?
Since its length is doubled, the number of molecules present increase, resulting in an increase in mass of the rod. And we all know that mass is directly proportional to inertia, therefore the moment of inertia also increases.
What tool do you use to measure length volume temperature and mass?
length: ruler volume: i dont know the name of this process. put it into a container with certain amount of water and measure the increase of water level. the volume is the base area of the container multiplies the increase of water level temperature: thermometer mass: balance (most preferably an electronic one)
What does the fetus have to do with pregnancy?
The fetus is what they call the unborn baby after 3 months of growing in the uterus. At that time it is now considered an unborn child or fetus instead of a blacocyst or mass growth of cells.
