The skier’s change in velocity is 8.33.../8.4 m/s.
21/63= 0.33...
0.33...x 25 s = 8.33.../8.4 m/s
Answer:
Without food your not able to produce energy thats why you cannot work so long
Answer:
a = - 3.14[m/s^2]
Explanation:
To solve this problem we must use the following kinematic equation:
![v_{f} ^{2}= v_{o} ^{2}+2*a*dx\\where:\\v_{f} = final velocity = 0 [m/s]\\v_{o}= initial velocity = 48.8 [m/s]\\ a = acceleration [m/s^2]\\dx = displacement [m]\\](https://tex.z-dn.net/?f=v_%7Bf%7D%20%5E%7B2%7D%3D%20v_%7Bo%7D%20%5E%7B2%7D%2B2%2Aa%2Adx%5C%5Cwhere%3A%5C%5Cv_%7Bf%7D%20%3D%20final%20velocity%20%3D%200%20%5Bm%2Fs%5D%5C%5Cv_%7Bo%7D%3D%20initial%20velocity%20%3D%2048.8%20%5Bm%2Fs%5D%5C%5C%20a%20%3D%20acceleration%20%5Bm%2Fs%5E2%5D%5C%5Cdx%20%3D%20displacement%20%5Bm%5D%5C%5C)
Now replacing:
![0 = 48.8^{2}+2*a*(378.7) \\-2381.44 = 757.4*a\\a = -3.14[m/s^2]](https://tex.z-dn.net/?f=0%20%3D%2048.8%5E%7B2%7D%2B2%2Aa%2A%28378.7%29%20%5C%5C-2381.44%20%3D%20757.4%2Aa%5C%5Ca%20%3D%20-3.14%5Bm%2Fs%5E2%5D)
The negative sign means the vehicle slows down.
Answer:
The <u>terminal buttons</u> of a neuron contain <u>synaptic vesicles</u> that house neurotransmitters
Explanation:
<em><u>Some terms explained:</u></em>
Terminal buttons:
The terminal Buttons of a neuron contain vesicles holding the neurotransmitters, they are the small knobs at the end of the neuron that send out information to other neurons. The terminal buttons essentially convert the electrical signals that reaches it into chemical signals.
Neurotransmitters:
Neurotransmitters are produced by the neurons in the axon terminal buttons and stored in the synaptic vesicles. Neurotransmitters are chemicals contained in terminal buttons that relays signals across the synapses between neurons. Neurotransmitters are the chemical messengers of the nervous system, they have an excitatory or inhibitory effect on another neuron.
Synaptic vesicles:
Synaptic vesicles are sacs in terminal button, they store neurotransmitters and release them into synaptic space in response to electrical signaling within the cell.
