Jaden has a mass of 45 kilograms on Earth. Jupiter has more gravity than the Earth. On Jupiter, Jaden's mass will be O more than

Dovator [93]

Answer:

m = 45 kg

Explanation:

Given that,

Mass of Jadan, m = 45 kg on Earth

Jupiter has more gravity than the Earth.

Mass of an object is the amount of matter contained inside an object. We need to tell about the mass of Jaden on Jupiter. The mass of the object remains same everywhere.It does not change in any of the location.

Hence, Jaden's mass will be 45 kg on Jupiter.

<h2>Answer: $13.5\times 10^{8}$ joules</h2>

Explanation:

From the first law of thermodynamics,

Δ $Q$ =Δ $U$ + $W$

Where $Q$ is the heat given to the gas,

$U$ is the internal energy of the gas,

$W$ is the workdone by the gas.

When pressure is constant,

$\frac{V_{1}}{T_{1}}=\frac{V_{2}}{T_{2}}$

$V_{2}=\frac{2.6\times 900}{300}=7.8m^{3}$

When pressure is constant, $W=P$ Δ $V$

Where $P$ is pressure and $V$ is the volume of the gas.

Given $P=1.5\times 10^{5}Pa$

Δ $V=$ $7.8-2.6=5.2m^{3}$

So, $W=1.5\times 10^{5}\times 5.2=7.8\times 10^{5}J$

Given that Δ $U=6\times 10^{5}$

So,Δ $Q=$ $6\times 10^{5}+7.8\times 10^{5}=13.8\times 10^{5}J$
