1 mol of atoms contains Avogadro's number of atoms. Avogadro's number =6.022140857(74)×10^23

So there are
1
4

×

N
A
nitrogen atoms in such a molar quantity of nitric oxide, approx.
1.5
×
10
23
individual nitrogen atoms. How many OXYGEN atoms in such a quantity?
Here I use
N
A
as I would use any other collective number: a dozen, a score, a gross. I am perfectly free to do so, because any physical scientist knows precisely what I mean by a
mole
.

If all other variables remain unchanged, what happens to the output force when the area of the input piston is doubled?

mars1129 [50]

Answer:

1250N

Explanation:

This question is based on pascal's Law.

So By Pascal's Law

=

therefore =force on input piston =25N

= Force or weight on output person.

therefore after putting the values we get,

= (25x 1500)/30

=1250N

Assume that the pressure inside of the 1 liter balloon is 200,000 Pa, what is the explosive energy in the inside the balloon? Ex

AysviL [449]

Answer:

200 Joules is the explosive energy in the inside the balloon. And that is $9.523\times 10^{-5}$ 1 lb of TNT.

Explanation:

$Pressure=\frac{force}{Area}=\frac{Force\times distance}{Area \times distance}=\frac{Energy}{Volume}$

Volume of the balloon = V = 1 L = $0.001 m^3$

Pressure inside the balloon ,P= 200,000 Pa = $200,000 N/m^2$

Explosive energy in the inside the balloon be E.

E = Pressure × Volume

$E=200,000 N/m^2\times 0.001 m^3=200 Joules$

1 lb of TNT = $2.1\times 10^6 J$

200 Joules = $200\times \frac{1}{2.1\times 10^6 }$ 1 lb of TNT

= $9.523\times 10^{-5}$ 1 lb of TNT
