1. The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
2. All the members of a family of elements have the same number of valence electrons and similar chemical properties.
3. The horizontal rows on the periodic table are called periods.
Answer: Force applied by trampoline = 778.5 N
<em>Note: The question is incomplete.</em>
<em>The complete question is : What force does a trampoline have to apply to a 45.0 kg gymnast to accelerate her straight up at 7.50 m/s^2? note that the answer is independent of the velocity of the gymnast. She can be moving either up or down or be stationary.
</em>
Explanation:
The total required the trampoline by the trampoline = net force accelerating the gymnast upwards + force of gravity on her.
= (m * a) + (m * g)
= m ( a + g)
= 45 kg ( 7.50 * 9.80) m/s²
Force applied by trampoline = 778.5 N
Electron transport is a stage of cellular respiration that involves a gradient of hydrogen ions filtering through ATP synthase.
<h3>Electron transport:</h3>
Aerobic respiration ends with electron transport. Energy from NADH and FADH2 is transferred to ATP during this phase. Hydrogen ions are pumped through the mitochondrial inner membrane and into the intermembrane gap using energy during the electron transport process.
The oxidative phosphorylation process, also known as the electron transport chain, is a collection of four protein complexes that combine redox events to produce an electrochemical gradient that results in the production of ATP. Both photosynthesis and cellular respiration take place in mitochondria. Hydrogen ions are pumped through the mitochondrial inner membrane and into the intermembrane gap using energy during the electron transport process.
