I would do the nervous system because nerves are what makes you feel everything around you and in order for you to be able to react you need the nervous system why? <span>The nervous system is the highway along which your brain sends and receives information and feelings about what is happening in the body and around it on the outside. This highway is made up of billions of nerve cells, or neurons which join together to make nerves. This is very important for the human to be able to live!</span>
Gassed condense because molecules decrease inside
Answer:
1. Find the molar mass of all the elements in the compound in grams per mole.
2. Find the molecular mass of the entire compound.
3. Divide the component's molar mass by the entire molecular mass.
4. You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.
Explanation:
Answer:
The compound amount is $303.03 .
Explanation:
Formula for compound interest:
Principle amount = $1100
Rate of the interest compounded semiannually :
= R = 9% = 0.09
Number of times interest compounded, n =
(semi means two times in a year)
Time period = T = 14
The compound amount is $303.03 .
Answer:
(a) ΔU = 7.2x10²
(b) W = -5.1x10²
(c) q = 5.2x10²
Explanation:
From the definition of power (p), we have:
(1)
<em>where, p: is power (J/s = W (watt)) W: is work = ΔU (J) and t: is time (s) </em>
(a) We can calculate the energy (ΔU) using equation (1):
(b) The work is related to pressure and volume by:
<em>where p: pressure and ΔV: change in volume = V final - V initial </em>
(c) By the definition of Energy, we can calculate q:
<em>where Δq: is the heat transfer </em>
I hope it helps you!
