What else can I help you with?
What does rapidly expanding mean?
increasing in mass at a great speed
Does the universe keep on expanding?
Yes, and so far, scientists have not yet accounted for enough mass in the universe for the expansion to ever come to a halt and start the universe contracting.
What does it mean when you say that the universe is below the critical density?
If the universe is ever to stop expanding and start contracting there has to be a certain amount of material (mass). This amount is called the 'critical density'. So far as is known to date the universe does not have sufficient mass to stop expanding, hence it is below the critical density.
Why a gun recoil when it is fired?
When a gun is fired, ignited gunpowder creates rapidly expanding gases that propel the bullet forward. The equal and opposite reaction force of these gases pushes the gun backward, causing recoil. The mass of the gun and the force of the expanding gases contribute to the intensity of the recoil.
A contracting cloud of gas and dust with enough mass to form a star?
a protostar
What are some ways the density of a substance can be increased and decreased?
The density of a substance can be increased by compressing it or increasing its mass without changing its volume. It can be decreased by expanding it or reducing its mass without changing its volume. Temperature changes can also affect density, with most substances expanding when heated and contracting when cooled.
What is a contracting cloud of gas and dust with enough mass to form a star called?
A nebula
What is an air mass turning rapidly called?
blizzard
What is caused by mass?
Mass movement is caused by gravity. (: also occurs when tectonic plates shift
Why do you think service industries are such a rapidly expanding part of society Think about the way good are made today?
The real necessities of life are mass produced one things that you keep alive like food, clothing and shelter are provided Buddhist will stop wanting more
In which lifework period on the graph does the mass of the fetus increase most rapidly?
The mass of the fetus increases most rapidly during the third trimester of pregnancy. This is when the fetus experiences significant growth and development, resulting in a noticeable increase in mass and size.
What cause's a mass movement?
A mass movement is caused by Gravity.
