Answer:
Not acted upon there is no motion
Forces acted upon there is motion
You can refer to the definition stated below:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... If that velocity is zero, then the object remains at rest.
Answer:
734.16 kg m/
Explanation:
The problem is asking for the Force of pushing off the ground.
- The formula of Force is: F = mass x acceleration
Given = <em>Mass</em>: 600 newtons (N)
<em>Acceleration</em>: 12 m/
We have to convert the mass into kg first. Remember that <u>1 kg is equal to 9.80665 newtons.</u>
Let x be the<em> mass in newtons</em>.
Let's convert: 
x 
= 
= 61.18 kg
Phil's weight is 61.18 kg
Let's go back to finding the force.
F = m x a
F = 61.18 kg x 12 m/
F = 734.16 kg m/
Ion
<u>Explanation:</u>
At the synaptic terminal, voltage-gated ion channels open, thereby stimulating the synaptic vesicles to release the neurotransmitters by exocytosis.
These ion channels are the signaling molecules in neurons. They are the transmembrane proteins that form ion channels. The membrane potential changes the conformation of the channel proteins that regulates their opening and closing. These channels play an important role in neurotransmitter release in presynaptic nerve endings.
For example - Ca²⁺ gated ion channel.
Between the two asymptotic gigantic branches, the Sun changes the greatest in size, brightness, and temperature.
