Answer:
through nuclear fusion
Explanation:
The burning of the sun is not chemical combustion. It is nuclear fusion. This combustion releases energy which we experience as the heat and light given off by the flame.
Answer:
Fnet = 12 N
Explanation:
Force on a point charge due to another point charge = kq1q2 / d^2
Force on +32uC = due to + 20uC + due to -60uC
where uC = 1 x 10^-6 C and k = 9 x 10^9 N m^2 / C^2
Net Force =

Explanation:
because the cup is a hard smooth surface you can hear the voice
Answer:
M=28.88 gm/mol
Explanation:
Given that
T= 95 K
P= 1.6 atm
V= 4.87 L
m = 28.6 g
R=0.08206L atm .mol .K
We know that gas equation for ideal gas
P V = n R T
P=Pressure , V=Volume ,n=Moles,T= Temperature ,R=gas constant
Now by putting the values
P V = n R T
1.6 x 4.87 = n x 0.08206 x 95
n=0.99 moles
We know that number of moles given as
![n=\dfrac{m}{M}](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7Bm%7D%7BM%7D)
M=Molar mass
![n=\dfrac{m}{M}](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7Bm%7D%7BM%7D)
![0.99=\dfrac{28.6}{M}](https://tex.z-dn.net/?f=0.99%3D%5Cdfrac%7B28.6%7D%7BM%7D)
M=28.88 gm/mol
