HELP ME! One airline limits the size of carry-on luggage to a volume of 40,000 cm^3. A passenger has a carry-on that has an area
EleoNora [17]
You must times the area by the volume, look at it as if the area is just one of 23 layers that makes up the volume.
1960x23=45080
so no it cannot be carried as it is 5080cm^3 over the limit

Give an example of mass making a difference in the amount of gravitational energy. Tell how you know the gravitational energy is
Andreas93 [3]

Answer:

The Gravitational potential energy at large distances is directly proportional to the masses and inversely proportional to the distance between them. The gravitational potential energy increases as r increases.

Examples of Gravitational Energy

A raised weight.

Water that is behind a dam.

A car that is parked at the top of a hill.

A yoyo before it is released.

A quantity of N2 occupies a volume of 1.4 L at 290 K and 1.0 atm. The gas expands to a volume of 3.3 L as the result of a change
lions [1.4K]

Answer:

\rho = 0.50 g/L

Explanation:

As we know that

PV = nRT

here we have

P = 1.0 atm

P = 1.013 \times 10^5 Pa

so we have

V = 1.4 \times 10^{-3} m^3

T = 290 K

now we have

(1.013 \times 10^5)(1.4 \times 10^{-3}) = n(8.31)(290)

n = 0.06

now the mass of gas is given as

m = n M

m = (0.06)(28)

m = 1.65 g

now density of gas when its volume is increased to 3.3 L

so we will have

\rho = \frac{m}{V}

\rho = \frac{1.65 g}{3.3 L}

\rho = 0.50 g/L
