Answer:

Given the information that PSR B1620-26 b is the oldest planet in the Milky Way, it is estimated to be about 13 billion years old, the planet is approximately 12,390 light-years away from Earth, this means that it would take 460,908,000 years to arrive at the ancient planet. If we want to reach this planet, we are going to need to make some gig “wrinkle in time” discoveries, or find ways to live much longer, considering that the current lifespan of humans is only 79 years.

alisha [4.7K]

Answer:

a) g(r) = 4\pi \cdot G \cdot \rho\cdot r, b) g = 4\pi \cdot G \cdot \rho\cdot r_{P}

Explanation:

a) The acceleration due to gravity inside the planet is:

dg = G\cdot \frac{\rho \cdot dV}{r^{2}}

dg = G\cdot \frac{\rho \cdot dV}{r^{2}}

dg = G\cdot \frac{4\pi\cdot \rho \cdot r^{2}\,dr}{r^{2}}

dg = 4\pi\cdot G\cdot \rho \,dr

g(r) = 4\pi \cdot G \cdot \rho\cdot r

b) The acceleration at the surface of the planet is:

g = 4\pi \cdot G \cdot \rho\cdot r_{P}

Heat is extracted from a certain quantity of steam at
vodomira [7]

Answer:v=2452.91 m/s

Explanation:

Given

initially steam is at 100^{\circ}C and converted to 0^{\circ} C ice

Let m be the mass of steam

latent heat of fusion and vaporization for water is

L_f=3.33\times 10^5 J/kg

L_v=2.26\times 10^6 J/kg

Heat required to convert steam in to water at 100^{\circ}C

Q_1=m\times L_v=m\cdot 2.26\times 10^6 J

Heat required to lower water temperature to 0^{\circ}C

Q_2=m\times c\times \Delta T

Q_2=m\times 4.184\times (100)

Q_2=4.184m\times 10^5 J

Heat required to convert 0^{\circ}C water to ice at 0^{\circ}C is

Q_3=m\times L_f

Q_3=m\times 3.33\times 10^5=3.33m\times 10^5 J

Q=Q_1+Q_2+Q_3

Q=(2.26+0.4184+0.33)m\times 10^6 J

Q=3.0084m\times 10^6 J

So this energy is equal to kinetic energy of  bullet of mass m moving with velocity v

Q=\frac{1}{2}mv^2

3.0084m\times 10^6=\frac{1}{2}mv^2

v^2=3.0084\times 2\times 10^6

v=2.452\times 10^3 m/s

v=2452.91 m/s
