In order to predict whether a star will eventually fuse oxygen into a heavier element, you mainly want to know about the star's mass.
<u>Explanation:</u>
Stellar evolution is procedure by which star experiences a succession of radical change during its lifetime. Depending upon the mass of stars, this lifetimes range from just two or three million years for most big to the trillions of years for a least massive, which is significantly longer or more than the age of universe.
All stars are conceived from falling billows of gas and residue, frequently called nebulae or sub-atomic mists. Throughout a large number of years, the protostar settles down into a condition of balance, turning out to be what is also known as the main- sequence - star.
Potential energy, is energy due to its position.
Given: Mass m = 40 Kg; Height h = 50 m
Required: Potential energy P.E = ?
Formula: P.E = mgh P.E = (40 Kg)(9.8 m/s²)(50 m)
P.E = 19,600 J
Answer:
In biological taxonomy, a domain (also superregnum, superkingdom, or empire) is a taxon in the highest rank of organisms, higher than a kingdom. ... The three-domain system of Carl Woese, introduced in 1990, with top-level groupings of Archaea, Bacteria, and Eukaryota domains.
so first your going to use v=Δd/Δt given you the answer 80 i think that's right
Answer:
Tom walked until he was 100 metres from his home. Then, he realised that he had dropped his homework, so he turned around and went 60 metres to pick it up again. He again turned back and started to walk faster to get to the bus stop on time. He got to the bus stop 100 seconds after leaving his home and waited for the bus.
