a car has a mass of 1,200 kg. what is its acceleration when the engine exerts a force of 600 n? (formula: f=ma)
vova2212 [387]
The answer is <span>0.5 m/s².</span>

The formula that will be used is
F = m · a
where
F - the force of the object,
m - the mass of the object,
a - the acceleration of the object.

It is given:
m = 1,200 kg
F = 600 N
a = ?


F = m · a
⇒ a = F ÷ m = 600 N ÷ 1,200 kg = 0.5 m/s²

Organisms with prokaryotic cells are separated into two.
wolverine [178]

Prokaryotic organisms are separated into two domains or groups: Bacteria and Archaea.

<h3>What are prokaryotic organisms?</h3>

Prokaryotic organisms are those whose cells do not have a membrane that delimits the cell nucleus and, instead, present their genetic material dispersed in an area called the nucleoid.

<h3>Characteristics of prokaryotic organisms</h3>

  • Prokaryotic cells form unicellular living organisms, belonging to the Archaea and Bacteria domains, depending on the preferred biological classification.

  • The Bacteria domain groups the most primitive prokaryotic organisms of all, they are dedicated to various types of metabolic activity: photosynthesis, such as cyanobacteria (blue-green algae), the decomposition of organic matter, etc.

  • The Archaea domain groups the archaebacteria or archaea, prokaryotic organisms that exhibit certain similarities with eukaryotic life, exist in very specific and generally hostile habitats (leading an extremophile life).

Therefore, we can conclude that the two domains, bacteria and archaea, encompass the world of prokaryotic organisms, that is, those that lack a cell nucleus.

In the light-dependent reactions of photosynthesis, photosystem I initiates the process to produce ATP and NADPH in photosystem
Tanya [424]
False the process is reversed. Photosystem ll happens before photosystem l. I know that's weird but it's true. In photosystem ll which happens first it makes the energy carriers for ATP Synthase to happen in Photosystem l which is the next phase. Hope this helped!
