In order to answer either of these, we need to know the energy content of coal ... like kwh (or joules or BTU) in each kilogram (or pound or ton) of coal.
When you start feeling extremely depressed and need a prescription drug to help you feel better. The medication you should take should have an effect on the neurotransmitter is : <u>Serotonin</u>.
Serotonin is a chemical that carries messages between nerve cells in the brain and throughout your body. Serotonin, also known as the "feel-good" chemical, is just another neurotransmitter. Serotonin performs numerous functions in the body, including those related to the gut, blood clotting, and sexual function, in addition to assisting with mood regulation.
Studies suggest that depression in some people may be complicated by low levels of certain brain chemicals, or neurotransmitters. The various classes of antidepressant medications may be able to reduce symptoms by restoring the balance of brain chemicals.
Depression is a quite very difficult condition to treat, even with the aid of drugs that help the brain's neurotransmitters balance specific neurotransmitters.

Answer:
400ft. 32ft/s -32ft/s
Explanation:
In reality the gravitational acceleration is 9.81 so the quadratic coefficient of the function should be 9.81/2
Anyway for the sake of assumtion let us takes=160t-16t^2
ds/dt=160-32t=0
t=160/32= 5 seconds.
s=160*160/32-16*(160/32)^2= 400 mts
s=384 mts
160t-16t^2=384
i.e
16t^2-160t+384=0
t^2-10t+24=0
(t-6)(t-4)=0
t=[4,6]
we have to take t=4 because it is all the up i.e <5
velocity =v=ds/dt=160-32t
v=160-32*4=32 ft/sec still going up
for all the way down take t=6 whuch is >5
v=160-6*32=-32 ft/sec (falling down!!!)
