Answer:
Protista
Explanation:
Protista is the first class of multicellular organism that arose in history. The first of this member is cyanobacteria.
Cyanobacteria is large group of photosynthetic organism that produce their own food by using light energy from sun and carbondioxide.
The first evidence of multicellularity is from cyanobacteria-like organisms that lived 3–3.5 billion years ago.
They help to can convert inert atmospheric nitrogen into an organic form, such as nitrate or ammonia.
Answer:
Assuming that the masses of the cars are the same
9 times
Explanation:
Kinetic energy can be computed using the formula:
Where:
KE = Kinetic energy
m = mass
v = velocity
As you can see in your problem, the velocity of the the first car mentioned is 3 times faster.
Looking at the the formula, velocity is raised to two (2). So if we put it in terms of equations this is how it will look:
Let v = velocity of the slower car
Car 1: velocity = (3v)
The increase is by a factor of 9.
Answer:
Scientists are using new computer models and evidence from meteorites to show that a low-mass supernova triggered the formation of our solar system. ... A supernova -- a star exploding at the end of its life-cycle -- would have enough energy to induce the collapse of such a gas cloud.
